Sounds like the reporting wizard has not been installed correctly. I’d suggest to just simply call LL.Design()
from code, see my Gist here:
Alternatively, you can try to register the wizard manually. Simply open a VS Command Prompt with admin rights and call
"C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\gacutil.exe" /i "C:\Program Files (x86)\combit\ll24\Samples\Microsoft .NET\Assemblies\Visual Studio Reporting Wizard\dll\combit.ListLabel24.ReportingWizard.dll"
"C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\gacutil.exe" /i "C:\Program Files (x86)\combit\ll24\Samples\Microsoft .NET\Assemblies\Visual Studio Reporting Wizard\dll\en-US\combit.ListLabel24.ReportingWizard.resources.dll" /f
You might need to adapt the paths to match your installations.
