Hello rocksplit, and welcome to the Seven Forums!
In fact, there should be a fix for this error, and it isn't too difficult WARNING! This fix was created specifically for this user! If you are not this user, do not follow these instructions!
: Ignore the above
Download the attached .zip file. Inside it, will be two folders, Packages and Manifests.
Create these folders if they do not already exist: C:\Windows\Temp\CheckSur\Servicing\Packages\
Extract Packs.zip onto your Desktop. Please place the contents of my Desktop\Packages
and my Desktop\Manifests
DO NOT place the .zip file in that folder, or the folders themselves. Make sure that a lot of files are in each of those Checksur folder.
Re-run the System Update Readiness Tool, and get me another copy of C:\Windows\Logs\CBS\CheckSUR.log
Also, please retest Windows Updates (with fingers slightly crossed, no matter how much we both know that that won't help! lol.)
Thanks a lot!
