'error 1311 source file not found' and installer 3.1 problem

Hi,

Thanks in advance for the opportunity to ask for assistance.

When I repaired XP sp2 after a problem with Trend MicroCillin 2007 the

Windows installer started to play up. I ended up uninstalling MS office 2003

after having installer popping up every time I tried to open Office progs.

When I tried to reinstall MSO 03 but got the following error message:

'Error 1311 source file not found

c:\msocache\allusers\90000409-6000-11D3-8CFE-0150048383C9\E3561406.cab'

I tried Windows install cleanup to remove the installer problem then

installed Windows Installer 3.1 also tried a full file upgrade of Office sp3.

Only got 'patch could not be installed errors'. Then tried reinstalling XP

sp2 with current upgrades - no good.

I saw a post elsewhere about changing the permissions on msocache - but I

can't even find the darn file.

I tried copying the files off the cd onto my hard drive - no good either.

That's it, I'm out of ideas. Stuck again.

Any assistance much appreciated

Regards

Jim
