Try this:
[ul][li]Go to Prefs / Misc / Explorer Replacement.[/li]
[li]Turning off Explorer Replacement and click Apply.[/li]
[li]Turn it back on and click Apply again.[/li][/ul]That may repair the registry settings.
I doubt it is anything to do with a Drive type - all of the hard drives, the CD ROM drive give the same answer. When I click on Control Panel it says in a windows titled "My Computer"
"Windows cannot find '(null)'. Make sure you typed the name correctly, and then try again. To search for a file, click the STart buttom, and then click Search."
CD ROM drives may also use the Drive filetype, but Control Panel shouldn't...
I would try reinstalling Opus over the top of your existing install. Do a settings export first, just in case, but it shouldn't overwrite any existing settings. The reinstall might repair registry settings.
Another thing to check: If you right-click a drive in My Computer, do any of the menu options work? (Open and Explorer should be like double-clicking, if Explorer Replacement is enabled, while Open in Directory Opus should open the drives in a new Opus window.)
The issue you speak of has nothing to do with Opus, rather a problem on the underlying Explorer system. This is what I've come across...
[quote]Just to let everyone know.... While surfing through the internet I found someone who solved this problem and has a way to fix it. There are 2 registry keys in the registry that are causing the problem. It affects the explorer.exe and iexplorer.exe files.
I tried to find the regkeys you suggested but they didn't exist at all.
When I right click in My Computer I can do everything but Open or Explore (Explore opens up Windows Explorer, while Open just gives the error message).
I'll uninstall and try again from scratch to see what happens....
Update: Reinstalling didn't work.... guess it will only be resolved when I decide to reinstall the OS.
Would still be nice to try and figure out what is causing this... before you reinstall your OS, could you export the whole registry as a backup and check things out fo what the open shell action has to say for the drive type compared to how things look 'post-reinstall'?
