I have a 6 year old Win7-64 system. I’ve never really had any issues with it I couldn’t solve myself but yesterday I tried to apply 11 monthly MS updates and they all installed fine except for the monthly security roll-up update, which failed with an error code of 80073701.
Some research for that error indicated that my system thinks file(s) needed for the update are missing or corrupted so I tried renaming the SoftwareDistribution folder so it would start with a fresh one. That did not work. I then ran the MS windows update troubleshooter tool but that also failed to fix it.
I then downloaded the MS System Update Readiness Tool and ran it (which took several hours). The log it generated seems to indicate that I’m missing a catalog file (Package_365_for_KB4088875~31bf3856ad364e35~amd64~~188.8.131.52.cat). There is then a long list of missing .mum files listed after that (over 900).
Looking at the Windows updates installed on my system, I do not see an install for KB4088875. However, a search of my registry does show keys for Package_365_for_KB4088875~31bf3856ad364e35~amd64~~184.108.40.206.cat. So something happened to that catalog file.
Do any of the Windows OS gurus here have any ideas on what I could do to fix this? If I can get that .cat file from somewhere and copy it into my catalog directory will that fix it? I also thought about uninstalling all the windows updates on my system and reinstalling them but that’s last resort stuff. I also thought about trying to do the anytime upgrade to Windows 10 to see if that would allow me to do updates again. Again, that’s more of a last resort shot at fixing it.
Here’s the first few lines of my SURT log file and the summary section following. I’d appreciate any advice anyone might have on how to get past this problem.
