I ended up downloading the ISO file and mounting it to do the repair install and get this - that didn't fix the office issue! How can that be?
Needed it anyway I guess after infection.
The repair install is system file related and not program file related.
It could be just down to compatibility issues that you have the same problem.
To determine if it is Office that is holding up the MDAC/MS Jet repair, create a system image onto external media, uninstall Office and then run the Windows Repair program again to see if it still hangs on that repair.
What problems were you having with Office and did its repair resolve those ?
If it's working okay and nothing else seems to be wrong with the machine, then you could just ignore running the WR program and get back on with life.
