G'day,
I feel like an absolute dope. I've been using computers since 1991. I should never have used a 'registry cleaner'.
I get this message "The specified procedure could not be found" every time I try to install a program, run an app such as to change the boot sequence, everything I have tried for days just crashes with the same result.
I have backed up all my files and just want to have the computer do a clean install on itself.
I can't even access a restore point - this same message comes up.
It shows the directory path and the name of the .exe that I am trying to use - even when simply trying to update Java:

If you can offer any suggestions I'd be very thankful.
Thanks
David
