Note: Ensure that the Addition.txt check box is checked at the bottom of the form within the Optional Scan area.
Press the Scan button.
Please wait for the tool to finish. It will produce two logfiles called FRST.txt and Addition.txt in the same directory the tool is run from (which should be the desktop)
Post the logfiles FRST.txt and Addition.txt as attachment in your next reply.
Did the issues you have with this machine started after the installation of microclaudia ?
Please uninstall that program completely to check, you may reinstall it later.
Reboot the machine and try to run the tool SFCFix again.
No, microclaudia has been installed long time ago, years. The problems started about 3 months ago.
I have uninstalled it, rebooted and SFCFix.exe throws same error.
