We recently switched some PC's to Windows 7 from XP. All the backups work as per normal in all moduiles except PO's where we get the following message POA(8.1): Error "An error has occurred while backing up the database files. Unable to load "ZIPDll.dll". This is consistent on all the Windows 7 systems, still work fine on the XP system we still have. Any thoughts?

What version of POA? It's working fine on my 64-bit Windows 7 machine with V8.1B (110325).

Andrew:
I have a client with the same message in POA but I don't think it's directly related to WIN7. They simply back up using another PC pending delivery of the new PO version from Softrak.

we do use 8.1B and have 64bit machines.

On a 32 bit OS, this DLL would be in \Windows\System32. In a 64-bit OS, it should be in \Windows\SysWOW64. (At least, that's the experience on my 2 most recent machines.

I have ZIPDLL.DLL in WIndows\SysWoW64 as well. I wonder if file doesn't get copied when the workstation setup is not done as RUN as Administrator. Many IT guys have told me that it doesn't matter when you are the Administrator, however I found that some things don't get updated properly.

That is a bit confusing, but System32 and SysWOW64 both are the links to same folder containing 32-bit DLLs. Windows x64 has a real directory System32 that contains 64-bit DLLs. Thus native processes with a bitness of 64 find “their” DLLs where they expect them: in the System32 folder. A second directory, SysWOW64, contains the 32-bit DLLs. The file system redirector does the magic of hiding the real System32 directory for 32-bit processes and showing SysWOW64 under the name of System32.

Mike:

To sum up, try copying the dll to your Windows\SysWow64 folder.
