I received the error when installing Adagio Ledger 8.0B (040618). I have other modules to install, namely:
* Adagio Datacare 8.0A
* Adagio Payables 6.8B
* Receivables 6.8B
* Order Entry 6.8B
* Inventory 6.8B
* Sales Analysis 6.8B
* Bank Rec 6.8B.

I was able to install all the modules mentioned above on the Windows 2003 Server R2, which is the 32-bit version of Windows 2003 Server. However, I received th error when trying to install on the Windows 2003 Server 64-bit version.
