We are having issues with the Centura application in Windows 7.  When the program is launched, the login box appears.  Once the mouse is moved to click in the login box, the application shuts down with the following error "Unrecoverable Error: This External Function can't be found.  Check the DLL and ordinal number"  We can logon if the mouse is not moved using the tab keys and the application opens up. But if the mouse is moved within the application i shuts down.  Our developers have take the application apart (DLL's registered, added) but no solution.
Thank you for any suggestions

Create a new user account ...user account might be corrupted.

Launch the app in clean boot mode

Clean boot process

Start-type - msconfig- click on startup tab- click disable all...then click services tab- put a check on hide all microsoft services ...and then click disable all....click ok and then restart the computer in normal mode.

If everything works fine in clean boot then enable five startup items and services at a time to find the faulty software.

Better yet, just start windows in safe mode. This will tell you if something third party to windows is causing the problem. Then you will know where to look in msconfig.

Application works fine with windows XP so no fault with the user account.

Starting in safe mode reveals no issues.

"Application works fine with windows XP so no fault with the user account"

User account gets corrupted because of faulty programs...did u try clean boot.

Can also try uninstalling your security software...reboot and check.

The application will not work on any Windows 7 pc, we have tested many.  Have uninstalled security software.  Still no joy I'm afraid.

Uninstall the application and reboot..

Now right click on the software setup file - properties- compatibility tab- select xp from the list and click ok....now try installing the app.

The problem is the app is not installed on the pc.  It is launched by a shortcut to the .exe on the server.

Disable UAC or lower down UAC setting from control panel...reboot the computer and check the exe app.

The program may simply not be compatible with Win7. Is your version on this list? I notice there is no Win7 column in a lot of the products...

So to that end, you could try XP compatibility mode.

It simply may not be compatible. I suppose if you are really stuck, you could set up a true VM with XP installed on the windows 7 machines (instead of compatibility mode). Or if this is something only some people use some of the time, set up a terminal server ($$$) or a couple of XP boxes ($) on a virtual machine that people can access when they need this program. Otherwise you might be out of luck.

You might be best to check with the vendor. They probably have more experience with their product in this situtation.

It turns out that there were two functions in the script referring to the mouse move. When these were commented out the application works fine.
