Error: Autochk cannot run due to an error caused by a recently installed software package.An unspecified error occurred__766f6c756d652e63 3f1

I don't think it is an AVG issue.  I think it's a Windows issue.  Just today, I went round and round with "Cannot open volume for direct access" message while trying to run "chkdsk /R c:"

It turns out that I had to completely remove Norton Security Suite 4 from the machine before it would successfully run.  After running chkdsk, I installed Norton once again and went right back to the "Cannot open volume for direct access" message.  I spoke directly with Norton tech support and they could not solve the problem.  The thing is, I have six identical machines and they all exhibit the exact same behavior.

Cannot open volume for direct access.  Autochk cannot run due to an error caused by a recently installed software package.  Use the system restore feature from the control panel to restore the system to a point prior to the recent software  package installation.

an unspecified error occurred (766f6c756d652e63 3f1)

I tried all of the proprosed solutions:

1.  Uninstalling Anti-virus  (no joy.)

2.  Chkdsk c: /f /r            (no joy.)

3.  Removing recently installed programs.  Removed (3) recently installed programs before coming to the conclusion that this is not working.

4.  Safe mode boot / system restore.  (no joy.)

Solution:  Run the hard drive as the second drive on another windows 7 system.  Run scandisk (check both boxes.)  Let it run.

Move the drive back to the original system and bang!!  it works!!!

Had to reinstall some programs but beats reinstalling everything or re-imaging.

Hope this helps somebody get through this non-sense.

Hello all,

Glad to know that you are issue has been fixed now Lowey58. Thank you MJC_UK for pointing Lowey58 in the right direction. This will help the other users with similar issue as well.

In most cases the Antivirus Software prevents the scan or installation of other software on the computer. In those scenarios it would be better to disable antivrus softwareand then re-enable the same once done with the scan/installation of the software.

yeah tried all of the solutions and none of them work

honestly I'm getting kind of tired of always having this problem, I try to run a system restore and it tells me to run a disc check, and when I do it tells me I need to run system restore, wasn't windows 7 designed specifically to avoid such redundancies? and all this started because of service pack one

I can't even just re-install windows because of a bad sector that your operating system can't fix

it's a good thing I hate apple and refuse to use Linux

what I need is to roll back my computer to before SP1, so maybe someone could tell me how to do so manually rather than relying on system tools that refuse to work?

In my case, the problem had to do with a bad entry in the system path environment variable.  More specifically, I had a UNC entry before the various systemroot entries in the system path.  Networking is not yet enabled during autochk so it's a no-brainer that an error would occur if an attempt to find autochk.exe used a UNC path; if only the error message was more helpful in the first place.  I had to use procmon's boot logger to find the problem.

The key for me is to put the systemroot entries at the very beginning of the system path:

c:\windows\system32;c:\windows;C:\Windows\System32\Wbem;\unc\path\here\if\needed;...

Hope this helps someone else.
