  • DLL Registration

SOLIDWORKS installs many .dll files that are required for the program to run properly, interface with the prerequisites and work in the Windows O/S environment. If you install without full LOCAL Windows Admin permissions it can prevent the needed registration of the .dll files. With the proper permissions, you can manually register the following .dll files to correct the issue.

 

  • dll (by default location – C:\Program Files\Common Files\SOLIDWORKS Shared)
  • dll (by default location – C:\Program Files\Common Files\SOLIDWORKS Shared)
  • dll (by default location – C:\Program Files\SOLIDWORKS Corp 20XX\SOLIDWORKS)
  • Note: 20XX is the version of your SOLIDWORKSTo manually register these files, follow the steps below. If you have any questions, please contact your CAD Admin and/or IT team before starting.

     

    1. Log into Windows with full Local Administrator permissions
    2. Using Windows Explorer, browse to find the .dll files from the previous page (some paths may vary based on O/S).
    3. Open a Command Prompt (CMD) as Administrator.
