I ran across this but I don't know anything about it. Just wanted to pass it along.

Try putting this in your mio, [Please Register or Login to download file] . The app is called Executability check. No installation is needed, just double click it from within the mio and browse to the program you are having difficulties running. And it will tell you if you're missing any dll files.

EDIT: This application appears that it might have limited information available. It will work with WinCE 4.2 but that might be all - might being the operative word here.

Is this about missing files in iGO only or missing DLL for any program? When the latter, better move this thread to 'GPS Software Utilities', please.

Not really sure but I think it might be for all. It may be also available for the computer. Someone who uses this download will have to tell us. But it does appear that Mio devices are included.

Tested on Windows Mobile and WinCE 4.2, Works ok, Does not work on my Mio M400 (WinCE 5) though.
