I have used the following to install a VB6 app on a workstation under XP:
-- Map Drive Z to \\computername\sharedfolder (UNC Path)
-- Using Setup from PDW install to Z:\
This works under Windows XP.

I have now added to the network another workstation that is running Windows Vista. I did the same drive mapping. When I attempt to install the app to Z:\ I get the following error: "Error determining allocation unit for Drive Z." Help!
