Hello Eustachio,
We've seen this error for the first time over the last week. We think we've identified the root cause and it sounds like you have already found the resolution. I'm sharing the below for context and to help other users should they hit this issue.
Error: Blue Prism Trial and Learning Edition: Database Setup Error: The file '' is invalid
Resolution: Restart computer and reopen Blue Prism
Root Cause: We believe the computers impacted would recently have had a Windows update that requires a restart. If a restart is not preformed, then new items that go into the Windows Registry go to a 'Virtual Area' until a restart is performed. Therefore, our Database setup is unable to read the Key which states where the location of the MS SQL Server 2017 LocalDB is.
