A reason that the message (that TREBB posted) is occuring is that a Windows registry path has been set to G, but there is no QRASP directory on the root of the G drive, or there is a QRASP directory but no Ledger report tables. I was able to duplicate that error message by editing the registry.
Conversely, I was able to make that error go away by editing the registry to a correct drive letter that has a QRASP directory and Ledger report tables within.

So the question is, what went wrong? Either the QRASP directory was moved to a different drive, or the registry had the drive changed to a different letter.
For the first situation, Adagio would not delete that directory nor move it. Has anything happened with the network? Or perhaps a peer-peer network is in use with multiple drive mappings?
For the second situation, was any other Adagio programs installed? This is important, as an incorrect drive selected during installation will cause other Adagio programs to fail with this error.
