Hello Harry, and welcome to Sysnative :)
Thank you very much for uploading that logfile. It helps immensely to see straight off what I am dealing with.
I may be required to send you quite advanced instructions during this fix. If at any time you do not completely understand something I have posted, or how to complete a task, please just stop and ask. I am always more than willing to provide further explanations or alternative methods, so please always just stop and ask if you are not 100% clear on something :)
Questions of any sort are always encouraged.
I would like to collect some more data before I begin the fix. To do this, please:
Click Start > Search for regedit > right click on regedit.exe > select Run as Administrator
Then go to the File menu in the top left hand corner of the window > Export... > put the dot in Selected Branch, and fill the text box with:
HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\Components
Give it a sensible name and save it somewhere you can easily find > Save
If you get any errors (such as "The selected branch does not exist. Make sure that the correct path is given."), please just let me know.
Finally, please navigate to the exported .reg file, right click on it > Send to > Compressed (zipped) folder, and upload the new .zip file here, just as you did with the CheckSUR.log in your first post.
Thank you :)
Richard
