Microsoft hotfix install over network fails 0x80070003

I have been been trying to figure this out for a long time now and have made no progress so I'm hoping someone can help.

I have an installer script to install a predefined set of Microsoft hotfixes on a new Windows 7 boxes. When installing from a network mapped drive with"

"C:\Windows\system32\wusa.exe" "Z:\Documents\OS_Hotfixes\Win7-2008\32bit\Windows7SP1\Windows6.1-KB2559049-x86.msu"

I get an error: Installer encountered an error: 0x80070003 The system cannot find the path specified.

If I run the same hotfix from the local machine:

"C:\Windows\system32\wusa.exe" "C:\Share\HostDocuments\OS_Hotfixes\Win7-2008\32bit\Windows7SP1\Windows6.1-KB2559049-x86.msu"

The hotfix installs just fine with no unexpected errors.

All hotfixes act the same way so it's not this specific one. I have also run sfc /scannow on the box with no success.

This is a Windows 7 SP1 32 bit host.

Can't say I know what's the installer's problem, but you can circumvent it if you just put it all in a script - copy the hotfix, run it, and delete the hotfix installation file.

Also, you should try putting the script, the wusa.exe and the update files in the same network folder.
