I was upgrading the veeam environment to version 11 and I was getting an error when trying to do the upgrade. At some point the main hard drive for the install had been changed and there were registry entries for Veeam that were causing issues with the upgrade. The error I was getting was:
Warning 1327.Invalid Drive H:
Really not an informative error. I searched through Google and couldn’t find anything aside from some references to checking the configuration. After doing that I wasn’t able to find anything I ended up having to go through the registry and all of the Veeam entries and finding one reference for Veeam pointing to the H:. Really painful and you would think they could make this error a little easier to find.
