Environment

BarTender 2021 R1 to R3

Fix/Answer

Please download an updated revision of BarTender. Once you have the new installer, please do the following:

1. Uninstall BarTender 2021 and reboot the system.
2. Install BarTender using the new installer you just downloaded.

If you are unable to update to the newest revision due to a validated system or the like, here is the legacy fix for Revisions 1 - 3:

1. Uninstall BarTender 2021 and reboot the system.
2. Install BarTender 2019
3. Upgrade to BarTender 2021 (when you get the error message during install, ignore and continue)
4. Then, take the ShellExtension.dll from another computer with a working Bartender 2021 and replaced it in the computer with the issue
5. Reinstall: Visual C++ 2019 and .NET Framework 4.7.2
6. Then run a repair on BarTender 2021; this allows the installation to work.
