If the issue is not resolved then upload checksur.log for analysis.

I ran into this issue on my laptop. You need to run the system update readiness tool as described above. Afterwards you need to open the checksur.log file located c:\windows\logs\CBS\checksur.log

At the bottom you will likely find a file or several files listed that could not be opened.

You need to get those files from another computer and place them in c:\windows\temp\CheckSUR\ then based on where you got the file drill down into the appropriate sub folder.

Once a good file is in that location run the system update readiness tool again and verify that the checksur.log file has repaired the corruption. If so try installing sp1 again.

If you run into any issues please let us know.

The problem though is that the comments by ded9 and thinkpads user were incomplete in that running the system update readiness tool alone will not solve this issue. Also the request for the checksur.log file is good but they do not tell the customer where that log is found. Since there was key information missing I commented and did not reference the previous posts because they were incomplete.

If the readiness tool won't work, it may be easiest and more stable now to reinstall Windows itself.

Reinstall is not required ..you can do repair install and then install updates.

Boot to desktop...insert the windows 7 disc...launch setup...click upgrade option....this will repair your windows install... complete the repair install.

You will not loose any data or programs during the repair install process

After repair your will be able to install service pack 1.

The suggestions to fix in place have not worked. The solution (ID:36716018) to reinstall Windows is the best option at this point. I will trust your best judgement on this one. Thanks. ... Thinkpads_User
