When I double-click on the desktop it does not open the program. I have Open the default Lister checked in the Launching Opus area and I'm using v11.18 x86.
First, make sure you're not running Opus as administrator with UAC enabled.
If you go to Preferences / Launching Opus / From the Desktop and select Disable, Apply, then select Open the Default Lister and Apply again, does it start working?
If it does work then, does it still work after a reboot?
It it does not work, try right-clicking a folder on the desktop and choosing the option to Open in Directory Opus. Does that work?
"First, make sure you're not running Opus as administrator with UAC enabled."
Done
"If you go to Preferences / Launching Opus / From the Desktop and select Disable, Apply, then select Open the Default Lister and Apply again, does it start working?"
No
"If it does work then, does it still work after a reboot?"
It still does not work even after reboot.
"It it does not work, try right-clicking a folder on the desktop and choosing the option to Open in Directory Opus. Does that work?"
Yes, that does work.
Can dopusrt.exe /dblclk be seen in the Task Manager process list?
Look for something like the highlighted line below:
Is anything in use that also hooks desktop double-click? e.g. I think DisplayFusion has such an option.
Or is anything in use that modifies the desktop? e.g. A tool like Fences may trap the double-clicks itself (but also lets you configure them to do things, as I remember, so you could make it launch Opus) and may also mean that the desktop window is no longer recognised as such, or is hidden behind another window and no longer receiving clicks.
"Can dopusrt.exe /dblclk be seen in the Task Manager process list?"
That specific listing is not there.
"Is anything in use that also hooks desktop double-click?"
No
"Or is anything in use that modifies the desktop?"
No
Is dopusrt.exe still not in the Task Manager process list after doing
?
Please also try updating to 11.19 since that's the latest version.
Try disabling your antivirus software as it may be killing the double click handler.
