Windows cannot find file when clicking on file?

I had the same issues. I finally reformatted my hard drive, for the
third time since December 2008.

HOWEVER, I tried this software that promised to fix my issues "Windows
can't find file fix" and it did NOTHING - the error messages were
exactly the same after installing the software, then before installing
the software.

The company PROMISES your money back, if the software doesn't work -
but the company, Security Stronghold, is intent on keeping their fee -
no matter that I am NOT using their software, it is NOT installed on my
computer and I am obvioulsy unhappy with their program and services.

I sent them a message immediately after realizing the software did not
work, and after a week, and my 3rd request for a refund, they responded.
By then, I had installed the "Free" True Sword software, hoping it
might fix my issue, and all it did was screw up my SQL Server. THAT led
me to reformatting my hard drive...

Needless to say, because I didn't get their permission to remove their
software - I am not entitle to a refund.

The point of this story is, stick with Microsoft. They will have a fix
for their issues eventually - you just have to find it. Third party
companies promising to be "experts" in Microsoft errors are sometimes
just scams, like Security Stronghold.
