V8.1.3 Launch Error Specified Vision Client No Longer Exist

Application was running on windows 10 Pro 20H2. Vision client gives launch error.
Any ideas for troubleshooting?

Most of the errors I see at launch can be fixed by deleting the cache file. I'm not sure about Client No Longer exists though.

C:\Users\USERNAME\.ignition\cache

Ignition will automatically rebuild it, and the corrupted or locked file will be replaced in the process

That suggests the launcher config file has been modified since that short cut last worked. Renaming an application in the launcher will break shortcuts that point at ti.

I have the same issue. Was deleting the cache file the fix?

My memory on this issue seems to be it was a permissions thing in a domain setting.

However prior experience dictates my memory not at 100%.
