This error code is supposed to mean 'Access Denied', and the solution given everywhere on the net (eg. https://stackoverflow.com/questions/3808954/dllunregisterserver-failed-with-error-code-0x80070005) is to open a cmd with Administrator rights. However, in my case, the same error occurs even on a cmd opened with admin rights (tested with the answers on https://stackoverflow.com/questions/7985755/how-to-detect-if-cmd-is-running-as-administrator-has-elevated-privileges).

Both
```
regsvr32.exe "C:\Program Files (x86)\GitExtensions\GitExtensionsShellEx64.dll"
```
and
```
 C:\windows\SysWOW64\regsvr32.exe  "C:\Program Files (x86)\GitExtensions\GitExtensionsShellEx64.dll"
```
fails with the same error message, that the given module was loaded but the call to DllRegisterServer failed with the code 0x80070005.

I tried to monitor registry accesses as given in http://www.cryer.co.uk/brian/windows/troubleshooting/nt4_dllregisterserver_in_com_failed_0x80070005.htm , but there are no ACCESS DENIED or ACCDENIED results at all in the resulting list.

Edit: I've now even tried
```
runas /user:Administrator "regsvr32.exe \"C:\Program Files (x86)\GitExtensions\GitExtensionsShellEx64.dll\""
```
from within a cmd that was itself run as Administrator but that too results in the same error!

  If you move the file to a non-protected folder does it work?

  @Ramhound Unfortunately yes, the same happens wherever I put the dll files.

  use ProcessMonitor instead of regMon to monitor the activity.

  @magicandre1981 Yes, I read that regmon had been merged into procmon so that's what I used. I made a filter to observe only regsvr32.exe to filter out the (tons of) noise, and also made it show only registry changes. There were many SUCCESS, REPARSE and NAME NOT FOUND results but no ACCESS DENIED.

And if the error persists... ?

@bigp perhaps then the entries in registry are already removed or somehow faulty
