After installation of SOLIDWORKS API SDK no project templates are shown in Visual Studio New Project dialog for C# and VB.NET

Cause

System error happened while installing the templates and registering the Wizard assembly in the Global Assembly Cache (GAC). This might be caused by permission issues.

Resolution

  • The MSI package is a zip storage. Extract (unzip) the file using any Archive tools which support zip format (such as WinRar, WinZip or 7-Zip)

If Access Denied error is displayed while registering the assembly in the GAC, you can use gacutil from Windows SDK and run it from the Command Prompt run as administrator gacutil.exe" /i ""
