Error While Opening Key

Recommended Posts

Not sure if this is in the correct forum, but here it goes.

Problem... after having a virus and getting it resolved here http://forums.malwarebytes.org/index.php?s...fuzzed&st=0

I have run into a problem trying to install some software. The installer says it cannot access the reg file.

When I run regedit, I get the error "Cannot open {26CE9193-6640-418a-B7DD-DC07D7F3BBBF}: Error while opening key.

I can not delete or change the key. It is located here:


The only other oddity is that I am not able to fully install a web cam. Of the two I tried, Skype does not recognize them even though they are certified by Skype. Not sure if this is related.

Microsoft Security Essentials and Malwarebytes Anti-Malware both turn up nothing. Everything else seems to be OK.

Yes I understand. There are a couple of potential issues.

What operating system is it? XP, Vista, Win 7 ?

Here is an example of resetting the permissions assuming nothing is wrong with the hard drive or Malware preventing access.

The Parent folder is located here and is where you'll change the settings: HKEY_USERS\S-1-5-21-527237240-790525478-839522115-1003\Software\Microsoft\Windows\CurrentVersion\Settings


Then right click on that tree path Settings and choose Permissions


Then make sure that your account and other Admin accounts have FULL access (if not let me know)


Then check the box to replace permissiosn as shown below but do not click OK yet.


Then click on the OWNER tab and select the Administrators account (which your own account should be a member of already)

and then click the check box to Replace owner on subcontainers and objects and click OK


You will get a warning dialog box similar to the one shown. Click yes to make the change.


Then close Regedit and reopen and see if you're still getting the same error or not.

You may have corrupted files on your disk. Please try running the following.

First close ALL Applications as this routine will automatically restart your computer.

Click on START - RUN and copy / paste the following entry into the box and click OK


Then try to change them again.
