Error relating to useless file extension

pauldb

I have the subject error and two files which have that error.

Is this a serious problem? How do I treat this or get rid of this error. This relates to jv16 Power Tools, latest version.

Can't find any help by searching for this error.

Thanks for any help.

jv16

I'm afraid I don't quite understand what you are asking, could you please give more details about the issue?

I do the following:

Open jv16 PowerTools

click Registry cleaner

click Start

look at Scanning Report, and close it

click Fix

click Backup

Look at Results Screen. All errors are now zero except Error Relating to Useless Extension which is 2/2.

If I click on + to expand the errors, I get

HKCR\{...}\

and

HKLM\Software\classes\{...}\

My question is, can I get rid of these errors safely? How? Or is it not worth doing?

Hope this helps, Paul

I manually added the first red key with RegEdit, which automatically created the second red key.

When run, the PT2009 1.9.0.606 Registry Cleaner showed them as "Useless file extension" errors, just like it did on your system. "FIX" removed and backed up those keys correctly. This was on an x86 Vista system.

Since they won't remove on your system, it is likely the keys have bad permissions. You could use RegEdit to try and find out what the permissions problem might be and try to fix it. If you don't want to do that, I suggest you put {...} in the "Ignore words" tab to hide the unremovable keys.

You could try to delete the HKCR\{...}\ key manually with RegEdit. However, if you get "Access denied," that also indicates a permissions issue.

Note: If your "..." is an ellipsis for a GUID string, the above explanation still holds.

Thanks for your reply. I downloaded the latest version: 2009PT 1.9.1.606, and reran the previously described procedure. The same two errors were found, but not removed. The ellipsis is as follows (between the brackets):

HKEY_CLASSES_ROOT\{80b8c23c-16e0-4cd8-bbc3-cecec9a78b79}\{KEY} : {KEY}

HKEY_LOCAL_MACHINE\Software\classes\{80b8c23c-16e0-4cd8-bbc3-cecec9a78b79}\{KEY} : {KEY}

Also, at the bottom of the "Results" the statement appears: "Windows core returned the follow error "5"" for each error.

Does this explain anything?

What are "Permissions"? How can I manipulate them? Where can I read more about them?

I am not experienced at modifying the Registry, and don't feel good about using RegEdit or similar software.
