Uninstalled Opus 9 From Vista Now: Application Not Found

I uninstalled the evaluation of Opus 9 from Vista and now when I double-click on a folder on the desktop I get an error dialog box that says the folder path and "application not found."

I can right-click folders and chose explore which gets me into them, but the normal windows shell seems to be messed up.

I think fixing it is probably as simple as re-associating folders with Windows Explorer (assuming this is the missing application) but you can't choose Open With in the context menu of a folder--only a file.

This is a big bummer, I feel like my OS is broken right now. Any help is appreciated.

The uninstaller is supposed to clean this up but I guess something went wrong.

You should be able to manually repair it using RegEdit:

[ol][li]Click Start -> Run and enter RegEdit.exe
[/li]
[li]Go to HKEY_CLASSES_ROOT\Folder\shell
[/li]
[li]There should be a default string value which is presumably set to openindopus -- change this to open
[/li]
[li]Do the same under HKEY_CLASSES_ROOT\ftp\shell[/li][/ol]Please let us know if this doesn't solve (all of) the problems.

This worked. Thank you very much. If i notice anything else funny, I'll post.

Hey there,

When I double-click a folder within another explorer window--it creates a new explorer window of that folder even though I have the Tools -> Folder Options -> General -> Open each folder in the same window option selected.

Any idea why this might be?

How would a DOpus setting have any control over Explorer?

I have no idea. All I can say is that this is the behavior I'm seeing and my Vista installation was a 3 month old install. I haven't dinked around with the shell except to install Opus and the previous setting seemed to be working before.

Perhaps the registry settings should be something other than open? A default action as specified in the GUI I'm talking about?

I'm confused. :frowning: Is Opus still installed on your computer or not? The first post was about uninstalling Opus but it sounds like Opus is installed now as you mention an Opus configuration setting.

If you right-click a folder in Explorer, which menu items are shown and which one is shown in bold?

Sorry, I'm not trying to be confusing--and I'm not pissed. Just trying to get my environment back.

Opus is uninstalled. The setting I'm talking about is inherent to the windows explorer. (In vista you have to hit alt to see the tools menu but it is there.)

This may be an opus config setting as well. It feels like opus made a change to how windows are opened in the shell, and that has overridden the settings I have in the GUI even though I'm not looking at opus windows.

Please let me know if I can provide more detial.

Sorry, I was indeed confused. I thought that was an Opus setting but, of course and as you say, it's an Explorer setting. I need to stop replying when so tired!

I'm not sure why Explorer is behaving as it is but perhaps the answer lies in some of the other registry settings. I've attached a zip with screenshots of RegEdit showing the relevant registry values on my Vista machine, when Opus is set not to replace Explorer. When Opus is in this mode, double-clicking folders in Explorer opens them in the same Explorer window.

By the way, it turns out that changing "openindopus" to "open" isn't exactly what Opus does when you disable Explorer replacement. In fact, it clears the default value completely. This shouldn't matter as when there is no default value "open" should be used anyway and on my system it doesn't matter whether it's "open" or nothing. I thought it might be wroth mentioning in case it does matter, though.

@nudel

Yes, that's the right action, as setting default value to nothing or deleting it altogether means the Default Canonical Action is to be used which is Explore for the Folder object.

By setting it to Open, then you ask for that specific action which is open in new window by default.

Maybe that'll fix it for jetsetter. Hope so. On my machine, though, it doesn't seem to matter whether the default action is open or nothing; double-clicks in Explorer open the folder in the same Explorer window either way.
