O&O Software Defrag - Registry Denied

poldo

I unfortunately purchased O&O Software Professional Defrag and installed it on my Xp sp3.

Uninstalling this software I used removal tool I got from O&O Support

Even if uninstalled, some O&O keys remain in the registry and at WindowsXp start-up these keys are always looking for non-existent DLL files (they stop loading the system !!)

JV16 2009 (1.9.1.606) registry cleaner removed the most O&O remained keys but about ten keys are still on

I made manually cleaner and I have seen that JV16 has not the permission to delete these keys (access denied)

I absolutely need to delete the keys, Please any advice welcome

Have you tried to delete the keys from Windows Safe Mode?

You could also try to use Windows RegEdit, right-click they key in question and select Permissions and make sure you have full access to delete the key.

If RegEdit also gets "access denied" for the keys, here is a procedure that might work:

Many thanks.

In safe mode I solved my problem.

For a beginners, as I am, It has not been very easy to understand that there were more registry keys to delete.

Keys which were ponting to an executable file and without any reference to the word O&O that I was looking for.

Jv16 has been extremely helpfull because it translates the key's numerical value in something readable and I was able to find

the guility "oodtray.exe" file

I have a question on the matter.

O&O Defrag software has been uninstalled, directories and folder have been deleted and nearly all registry keys have been deleted also.

There were only 4 keys pointing to the executable file (oodtray.exe).

Why did not JV16 valued as "errors" these keys pointing to nothing ?

Regedit in safe mode has been a good lesson. I found many registry keys (example: favorites of explorer) which all were pointing to

deleted reference. I think these would be "errors"
