Operating system requirements and information

Solid Edge ST4 has been certified to run on the following:

  • - Windows XP Professional operating system (32-bit or 64-bit) with Service Pack 3
  • - Windows Vista Business or Vista Enterprise operating system (32-bit or 64-bit) with Service Pack 2
  • - Windows 7 Enterprise, Ultimate or Professional (32-bit or 64-bit) with Service Pack 1
  • - Internet Explorer 9 (IE 6.0 meets minimum requirements)

                       Note:  Internet Explorer is not required to be the default browser.

Note:   The Alvira freeware anti-virus program on Windows platforms occasionally misidentifies some NX DLLs as contaminated with a virus. If you are using Alvira and NX on a Windows machine and encounter this problem, please use the Alvira option to exempt the files from scanning by Alvira.


Hardware system requirements

Solid Edge is not supported on Intel Itanium processors.

 Recommended system configuration

  • - 32-bit (x86) or 64-bit (x64) processor
  • -Windows 7 operating system for optimal performance and user experience
  • -At least 2GB RAM
  • -True Color (32–bit) or 16 million colors (24–bit)
  • -Screen Resolution: 1280 x 1024 or higher, widescreen format
  • -3 GB disk space required for installation

 Minimum system configuration

  • - 32-bit (x86) or 64-bit (x64) processor
  • -Any of the above operating systems
  • -At least 1GB RAM
  • -65K Colors
  • -Screen Resolution: 1280 x 1024 or higher
  • -3 GB disk space required for installation

Solid Edge stops certifying new releases against an operating system shortly after

Microsoft drops mainstream support for it. Microsoft dropped mainstream support for XP in April 2009. Solid Edge ST4 is the last version to install on Windows XP. For ST4, we will not address XP operating system related issues or provide XP-specific fixes. Solid Edge ST5 will not install on XP.

It is not recommended that you run Solid Edge on Server operating systems.

Solid Edge will not install on machines without Internet Explorer 6.0 or higher. Internet Explorer is not required to be the default browser.

Solid Edge is not supported on Intel Itanium processors.

The 64-bit version of Solid Edge requires Microsoft 64-bit Windows XP, 64-bit Windows Vista, or 64-bit Windows 7 operating system loaded on Intel EM64T or AMD64 processors. (More details are below under System Resource Requirements and Information.)

The 32-bit version of Solid Edge has been certified to run on 64-bit Windows XP, 64-bit Windows Vista, or 64-bit Windows 7 as a 32-bit application. Below are the known issues running on these operating systems. The workaround is to use the 32-bit Internet Explorer.

  • - The “Status” and “Project” tabs are not displayed on the File Properties dialog if activated from Windows Explorer.
  • - Solid Edge Web Parts do not display if running the 64-bit version of Internet Explorer. The user is prompted to install the .NET framework.


Windows 7 and Windows Vista Recommendations

 User Account Control (UAC)

The User Account Control (UAC) on Windows 7 and Windows Vista prevents the proper installation and removal of Solid Edge.

The Solid Edge installation performs best with UAC be set to off. If you plan to run Solid Edge with UAC on, you should install the Solid Edge application to a location where the user has write permissions. This location should be somewhere other than c:\Program Files.

To turn off UAC on Windows Vista, select Control Panel -> User Accounts ->User Accounts -> Turn User Account Control On or Off.

To turn off UAC on Windows 7, select Control Panel -> User Accounts -> Change User Account Control settings -> “Never notify”.

Windows Vista Aero

It is strongly recommended that you turn off Windows Vista Aero if you will be working with View and Markup or the Solid Edge Viewer. To turn off Windows Vista Aero, follow these steps:

  1.  Go to Control Panel.
  2.   If Control Panel Home is selected at the far left of the screen, then click Appearance and Personalization, click Personalization, and then click Window Color and Appearance.
  3.  If “Classic View” is selected at the far left of the screen, then click Personalization, and then click Window Color and Appearance.
  4.  If you see Window Color and Appearance at the top of the window, then you should have “Open classic appearance properties for more color options” at the bottom of the window. Click it. In the Appearance Settings window, change the color scheme from Windows Aero and click OK.
  5.  If you don’t see Window Color and Appearance, but see Appearance Settings, then check to make sure the Color scheme is not set to Windows Aero and click OK.

Note:   If you see the Appearance Settings dialog box instead of the Window Color and Appearance window, then the theme might not be set to Windows Vista, the color scheme might not be set to Windows Aero, or the computer might not meet the minimum hardware requirements for running Windows Aero.

Windows Vista Aero requires a DirectX 9–class graphics processor that supports the following:

  •  -WDDM driver
  • - Pixel Shader 2.0
  • - 32 bits per pixel
  • - 256 MB graphics memory


Display System Requirements and Information

Solid Edge will run on graphics drivers that support Windows XP or Windows Vista or Windows 7. Contact your graphics driver manufacturer to determine whether their graphics adapter/driver support these operating systems.

For optimal performance, it is recommended to use a professional graphics card that is designed for CAD applications. For information about cards used in testing Solid Edge and results, refer to

At least a 256MB graphic card is recommended when working with large assemblies or complex parts.

Note that running with extremely high screen resolution and color depth increases the memory requirements on the system and may result in apparent performance degradation. If experienced, reconfigure the display system to the recommended resolution and color depth for improved performance.

When running Solid Edge, if you experience an abnormally high abort rate, parts disappearing, or other graphic anomalies you may not be using the appropriate graphics driver. For more details, visit

Also setting Display Fonts to Large Fonts or Extra Large Fonts (larger than 96 DPI) may cause some Solid Edge user interface items to not display as intended. Recommendation to resolve these would be to use Normal Fonts (96 DPI).

A wide-screen ribbon layout has been added for Solid Edge. This new ribbon layout is optimal for horizontal screen resolutions set to 1920 or above. Solid Edge automatically detects your resolution and sets the ribbon layout to wide-screen starting at horizontal resolutions 1600 and above. You will see some group collapsing on the right side of the Ribbon on resolutions between 1600 and 1920.


System Resource Requirements and Information

Earlier versions of Solid Edge were enhanced to access the extended address space that is available on Windows. All running processes, including the Operating System process, share 4 GB of addressable memory available, regardless of the amount of physical RAM. Normally, the operating system reserves 2 GB of space and leaves 2 GB for applications. Running 32-bit operating systems with the /3GB switch added, reserves only 1 GB for the operating system, and leaves 3 GB for applications. This allows you to work with larger datasets without running out of addressable space.

On XP, you set the /3GB switch by editing the boot.ini file. You must have admin privileges to do so. Here is a sample boot.ini that contains a 3 GB switch.

 [boot loader]
[operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP Professional”
/fastdetect /NoExecute=OptIn multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows /fastdetect /NoExecute=OptIn /3GB

On Vista with administrator privileges, you can run the following command from the command line to enable /3GB switch:

 BCDEDIT /Set IncreaseUserVa 3072

 This command will tell you what options are part of the OSLOADER family:

 bcdedit /? types osloader

To reset the value, use:

 bcdedit /deletevalue IncreaseUserVa

With Solid Edge V18, we announced support for running our existing 32-bit Solid Edge application on Microsoft Windows XP Professional x64 Edition with Intel EM64T or AMD64 processors. This allowed Solid Edge customers to address 4 GB of physical memory and virtual memory. With Solid Edge V19, we developed a new 64-bit Solid Edge application, in addition to the existing 32-bit version. The 64-bit Solid Edge supports up to 128 GB of physical RAM and 16 terabytes of virtual memory, enabling applications to work with larger data sets. The 64-bit version of Solid Edge requires Microsoft 64-bit Windows XP operating system or 64-bit Vista operating system loaded on Intel EM64T or AMD64 processors. The 64-bit version of Solid Edge should only be used if you need more than 4 GB of physical memory because you are running out of memory today when creating very large assemblies or drawings. The 64-bit version of Solid Edge is available by request.

Page file size should be the maximum size possible. In general, the page file size should be at least twice the amount of memory in the machine, plus the size of files you will use.

To better manage the system memory resources while running Solid Edge, it is important to turn off the option to “Show window contents while dragging”. This prevents unnecessary allocation/deallocation of memory for displaying the window contents while dragging a window. To change this option, go to Control Panel ->Display.

Future Processor Support

Component software delivered with Solid Edge, such as Parasolid and D-Cubed, started phasing out processors not supporting Intel’s SSE2 (Streaming SIMD Extensions 2) instruction set. In 2009, these components will only support processors with SSE2.

SSE2 is one of the Intel SIMD (Single Instruction, Multiple Data) processor supplementary instruction sets first introduced by Intel with the initial version of the Pentium 4 in 2001. AMD added support for SSE2 with the introduction of their Opteron and Athlon 64 ranges of AMD64 64-bit CPUs in 2003.

Here is a list of common processors that do not support the SSE2 instruction set:

  • -AMD CPUs prior to Athlon 64
  • -Intel CPUs prior to Pentium 4

Starting with the ST2, Solid Edge only supports processors that include the SSE2 instruction set. The Solid Edge ST4 installation checks for the presence of such a processor. If this processor does not exist, ST4 will stop the install and display a meaningful error message.


Temp File Space

Solid Edge uses temp file space for saving files and for storing memory mapped display files. Using temp file space when saving files helps significantly reduce the size of the resulting file on the destination file system.

Users should ensure they have twice the size of the largest file being saved available as free temp file space prior to saving their files. Note, 2x the file size for an assembly should include the size of the assembly, plus the size of the subassemblies that are being used, plus the size of the part files.

Running SE will create files with .000, .001, etc. extensions. These are memory mapped files that are used in the display pathway. When an assembly or part file is opened, memory mapped files are created in the temp directory during display of the assembly/part. These files are cleaned up by Solid Edge when the process exits.

If the user is running short on temp space, they can optionally set an environment variable called JRENDER_TEMP and point it to any folder with sufficient space. If this variable is defined, Solid Edge will create memory mapped files in that folder.

Running SE will create a file named DCCACHE.CAC in the system temp folder. This file is a cache of the file icons displayed on the FILE OPEN/FILE SAVE/BROWSE dialogs.

When a Solid Edge file is opened, but Solid Edge cannot gain exclusive write access to that file, a message box is displayed stating, “The requested file is currently write locked, open as read-only”. If the user selects the copy button on this message dialog, the file will be copied to the temp folder using the naming convention tmp {filename}.par, tmp{filename}.psm, tmp{filename}.asm, tmp{filename}.dft.

It is good practice to periodically check the files in the temp folder when not running Solid Edge and delete any that might remain from an abnormal termination of Solid Edge.
