Could not load SOLIDWORKS DLL: GdtAnalysisSupport.dll

 Problem

When trying to open SolidWorks and we get an error “Could not load SOLIDWORKS DLL: GdtAnalysisSupport.dll“

 Solution

Step 1. Open Command Prompt as Administrator

Go to Windows Start > type in cmd > right-click > Run as administrator.

Step 2. In Windows Explorer, navigate to SolidWorks installation location (where sldworks.exe is contained)

Step 3. Drag and drop sldworks.exe into the command prompt and type /regserver

*if drag and drop does not auto fill the file path in the command prompt, manually type in the command.

Typically, the command would look like,

“C:\Program Files\SOLIDWORKS Corp 2021\SOLIDWORKS\sldworks.exe” /regserver

Step 4. Press Enter. This will register sldworks.exe

Step 5. Reconfirm behavior.
