Dopus 13 not running after install

If you didn't reboot after installing the new version, please try that.

If that doesn't help, there's a way to make Opus report how far it has got during startup, which might tell us where it's going wrong.

This requires a registry change.

Easy method:

Manual method:

  • If you prefer to use RegEdit manually:
    HKEY_CURRENT_USER\Software\GPSoftware\Directory Opus
    StartupProgress (DWORD) = 1.
    (Then later delete it to turn it off again.)

You'll also need to download Microsoft DebugView. This doesn't need installing; just unzip it somewhere and double-click it. Later, when it's no longer needed, simply delete it.

With DebugView running, launch Opus.

DebugView should display some lines similar to dopus: Startup progress: 31 (plus some timestamps and other information next to it).

(DebugView may default to very narrow columns. If everything is truncated they just need to be dragged wider. Other programs may also send output to DebugView, so not everything it displays will necessarily come from Opus.)

If there's nothing in DebugView from Opus, make sure the registry value is set. If it is, it's possible Opus is being blocked from starting at all, and control never reaches our code. That would usually be due to antivirus or similar. It could also be other types of conflicts, but that's what I'd check first.
