Hello i recently upgraded to the latest Directory Opus 10.0.1.3 beta X64. I run Windows 7 64 bit version. I don't know if the problem was there before because i created these buttons today.
Anyway the problem is that all custom commands like
Yes a dopus crash dump is created for every time a crash has happened i got 8 crash dump files now. I also tried DOPUS 1.0.1.0 a non-beta version it also crashed.
Please contact GPSoftware support and let them know you can send them the crash-dumps. They should be able to use them to get a better idea of where the crash is coming from, if any 3rd party DLLs (shell extensions usually) may be involved, etc.
I have contacted them and i managed to fix the problem by deleting all configuration data available.
Sadly the command like notepad {filepath} still does not open the selected file and the button only works when there is no file selected then it just runs notepad.
It might be worth a try to uninstall Opus, reboot, then reinstall Opus. (That should wipe the config completely, and also ensure all the components are consistent and registered.)
Everything works very well with the previous beta Directory Opus 10.0.1.2 beta X64. The command works exactly as it should with no problems at all. So the newer 10.0.1.3 beta seems to have some serious issues.
If some versions (10.0.1.0 and 10.0.1.3) are having problems and intermediate versions (10.0.1.2) aren't, that makes it likely that some component is corrupting memory and the code moving around slightly in each version is causing that corruption to have more or less of an effect.
The crash-dumps may reveal more, so it's probably worth waiting for those to be inspected.
If you want to try things in the meantime, here's a list of suggestions. Things involving columns, thumbnails, plugins, codecs and shell extensions are most likely to be relevant.
