I ran the exe and the problem persist.
-I uninstalled an reinstalled the software and no luck. I suspected it was a problem with the build included with LabVIEW 2021 so I downloaded from your JKIs Web page.
-I also noticed the icon for the .vip file is not the right one.
-I ensured it tries to open the file with VIPM File Helper. I had an Issued with VIPM 2020 las year where the reference was to the VIPM.exe not Helper.
I hope the images help.
