Since the latest Windows update I am getting an Unhandled Exception error when I try to start DO. I have uninstalled, reinstalled, rebooted etc but still get it. Any ideas please?

Could you post a screenshot of the error?

If you haven't already, please try using the latest beta ( [Directory Opus 13.11.4 (Beta)](https://resource.dopus.com/t/directory-opus-13-11-4-beta/53646) ) in case it's something that was fixed recently.
If that still has the problem, we might be able to work out the cause from some [process snapshots](https://resource.dopus.com/t/manually-generating-process-snapshots/34071), made while the error message is still on-screen.
(I would not worry about hardware errors, unless you're seeing random issues with other software as well. This is more likely to be a bug in either Opus or a DLL something has installed on the system which gets loaded during startup.)

Could you have a look and see if you have "NOKL" installed, as this was the cause of a very similar error in this thread here:

Hi Jon
Oh yes, I use it quite a bit!
Apart from choosing between NOKL or DO, was there a solution?

We should have a fix for it in the next update; in the meantime you could rename the shell extension DLL (or just not use Opus!).

We've put the fix into the [latest beta](https://resource.dopus.com/t/directory-opus-13-11-5-beta/53716) if you want to give it a try. Please let us know if it fails to resolve the problem.
