“Value does not fall within the expected range” when trying to add a reference in a project

Question

I did a ‘devenv /setup’ and that fixed it.

Detail

Exit Visual Studio
Click Start
Type cmd, right click Command Prompt and select Run as administrator
Navigate to the appropriate Visual Studio folder
VS2012: pushd %programfiles(x86)%\Microsoft Visual Studio 12.0\Common7\IDE
VS2015: pushd %programfiles(x86)%\Microsoft Visual Studio 14.0\Common7\IDE

VS2017: pushd %programfiles(x86)%\Microsoft Visual Studio\2017\<Edition>\Common7\IDE

VS2019: pushd %programfiles(x86)%\Microsoft Visual Studio\2019\<Edition>\Common7\IDE
Type devenv /setup and press enter
When the command prompt returns, you’re done. Close the command window, reopen Visual Studio, and test to see if the error’s resolved.
