My installation package has been installing fine on most of my client's machines, but it fails on two machines (both Win/2000) with the following error: "Error 1327, Invalid drive U:\"

What is error 1327? Is there any place where InstallShield error messages are documented?

I have a U: drive on my development machine, but as far as I know, there is no reference to the U: drive in the parameters I supplied to InstallShield. Also, there is no U: drive on the machines where the installation package has installed successfully.

Thanks, Chaim
