Error accessing the registry

[notuo]

Hi all and merry hollidays. I got a problem you may be able to help me...

Yesterday I did a fresh installation of my W7 professional. Before that I backup the things I know I need. One ot them was to backup a branch from the registry to keep some details for a program I have.

Today I reinstalled that program but when I double click in order to incorporate the branch I got this error: "error accessing the registry".

I did clean registry with glaryutils and also tried with resplendence registry tools lite (this time no error but with no luck at all.

Any ideas?

Thanks in advance to all.

Try right clicking on the file, then click "Run as administrator". If prompted, enter your admin credentials.
