chkdsk not working

Anyone think running Chkdsk from the WinRE would help?

I was able to replace a TrustedInstalled file by running SFC offline, but the other version was not corrupted. The OP does have two computers and does have access to another autochk.exe file. But maybe running the chkdsk would repair the problem the OP has now.
Too late - I have already reinstalled, but thanks for your suggestion.

BTW - the laptop had its own recovery partition and even that had become corrupted. Luckily managed to find the recovery disks.
