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

visual-studio, visual-studio-2013, visual-studio-2019

Solution

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.

Problem

Suddenly I am getting this error "Value does not fall within the expected range" whenever I try to add a reference to any project. This also happens with a new blank project. It can list the current references fine. I rebooted the computer. I am not sure if the recent Update 2 caused this. This is my first add reference since the update. I am using Visual Studio 2013 on Windows 7 64bit. Any ideas?
