Hi,

I have disabled "Allow multiple instances" but every now and then a new instance is nevertheless opened.

It doesn't seem to follow any particular pattern except that whenever I do a "View source" from IE it opens a new instance of UE.

Any help would be appricated.

Oh and I am using UE 12.10a

Hi Mofi,

First of all thanks for the answer.

I tried disabling "Allow muliple instances" in all the instances that opened, but to no avail.

Secondly I searched my harddrive as you described but only a single uedit32.ini file came up and it had Multiple Instances=0.

I have another copy of UE on another harddrive but that harddrive has got its own copy of windows that UE was installed in.

The detection of an already running instance works only if the application is started with the same path. That's the reason why I asked for a second uedit32.exe.

I think on your computer there are different paths to uedit32.exe. Look at all shortcuts (*.lnk) which contain uedit32.exe if they all have the same and correct long path to uedit32.exe. Start Regedit and search also for all occurrences of uedit32.exe and check the paths. They should be all identical and should be all correct. Check also the environment variable Path if it contains the path to uedit32.exe and if so, if it is also correct and only once present.

Have you upgraded your current installation from a previous one? The default installation directory has changed in the past and so it's possible that in the registry different paths to uedit32.exe exist, but the EXE is found automatically by Windows via the Path variable or the uedit32.exe key in "HKLM\Software\Microsoft\Windows\Current Version\App Paths" or other caches in the registry.

Search in the whole registry also for ue32ctmn.dll and check the path to it. It must be the same as to uedit32.exe.

My last advice is to use Filemon and Regmon from Sysinternals to detect what's going wrong on your computer.

Mofi my man you just saved my day - again

I searched the registry and found several places where the path pointed to my second harddrive.

After changing it UE is back in action, working like a charm.

Once again thanks.

If the second of the two checkboxes below is marked and the first one NOT, you will still get multiple instances. Is this the designed behaviour (as of v15.00.0.1046)?

From Help file:

Allow multiple instances
The Multiple Instances item determines if another instance of the editor is opened if the editor is invoked when an instance is already active. If this option is enabled a new instance is opened each time the editor is invoked. If this option is not enabled only a single instance of the editor is opened, and any additional requests result in the first instance becoming active with the new file loaded in addition to any files already open.

Files selected in Explorer will open in a new single instance
If this option is selected, and multiple files are selected at once in Windows Explorer, and UltraEdit is selected from the context menu, all selected files will be opened in a single new instance. If this option is not selected, each file selected may be opened in a separate instance.

I have eveything as you suggest and the dll is correct also, but something has changed.
I used to be able to type in a dos window --> uedit32
and I would be back in the instance already open. Now I get multiple instances.
Also if I type --> uedit32 x.txt
It starts a new instance (always now), never did before. I always have liked one instance. I am running xp sp3.

Sent information to UE and they tell me they do not have this problem. It is killing me with lots of instances opening up. Maybe with some other folks letting them know this is really a problem. I tried a complete uninstall and removed registry settings. Problem is still here.

Thanks,
Steven
