Hi Bill,
Versions of Adagio? Might make a difference, if any programs are prior to 9.2A and use the old Report Tables drive.
Windows - User Account Control enabled or not?
I recall an issue from a couple of years ago that how the drive was mapped, in a terminal services environment, where the drive letter was not recognized as active in Windows, and thus the UNC path was needed in the shortcut to locate the Adagio program. Not exactly the same as what you are describing, as you are attempting to install, but this is something to consider.
