Troubleshooting build errors for add-ins in xCAD

Insufficient Permissions

Symptoms

Requested registry access is not allowed

or The command 'regsvr32' exited with code 5

error is displayed during the build process.

Cause

Registration may require administrative privileges and IDE (e.g. Visual Studio or Visual Studio Code) is not run As Administrator

Resolution

Run IDE As Administrator
If the above does not help, try deleting the bin folder, in some cases it can resolve the issue
Alternatively, disable automatic registration and register add-in manually from the command line

Embedded SOLIDWORKS Interops

Symptoms

Could not load file or assembly 'SolidWorks.Interop.Published' error is displayed when building or cleaning project.

Build error due to interop libraries being embedded

Cause

xCAD (when used in .NET Framework) requires the the SOLIDWORKS interop files to be available in the output directory for the proper loading.

xCAD automatically sets the Embed Interop Types option to False for all necessarily libraries when nuget package is installed. However in some cases (upgrade to package or specific version of Nuget package manager) this may result into the libraries to be set as embedded.

Resolution

Manually change the Embed Interop Types option to False for the SOLIDWORKS interops.
