SongKong does not run any applications!

I updated Song Kong! Now I can open it, but it doesn’t do anything. For example, when I try to start Song Repair, a window opens briefly and then closes immediately, and nothing happens! What could be the problem? Best regards, Thorsten Theimann

Try Admin:Empty Database and retry, if that doesn’t work please run Admin:Create Support Files so I can check your log files.

Okay…I will see Thanks a lot!

I´ve create Support Files so i´am waiting for your Answer!

There are a few errors in here but not sure which are critical, just so I am clear what date did it last work?

I can see this error when you run Match to One Album, but is not clear why you are getting this error, I can adjust code to handle no songs but can’t see why is it not finding any songs.

But there is some evidence you may have two copies of SongKong running at same time, perhaps one is invisible from a previous issue so I would suggest:

  • Computer Restart
  • Start SongKong
  • Run task

and see if that resolves it

The last update that was released, I think that was about 4-6 weeks ago!

I’ve tried everything but it still doesn’t work…unfortunately!

Maybe I should completely delete SongKong and then reinstall it?

Hi, if you tried

  • Computer Restart
  • Start SongKong
  • Run task

and it still fails please run Create Support Files again.

Hi, thanks okay there seem to be some serious problems with the installation/configuration

First check you have remaining disk space if not run:

  • Admin:Empty Database
  • Admin:Delete Report

If disk space is okay the easiest thing to do would be

  • Copy any .properties files within C:\Users\username\AppData\Roaming\SongKong (where username is your username) to another location
  • Delete C:\Users\username\AppData\Roaming\SongKong
  • Uninstall SongKong
  • Reinstall SongKong
  • Restart SongKong
  • Reinstall License
  • Run Test

If all okay, but you had some custom config you want to recover

  • Exit SongKong
  • Copy .properties files into C:\Users\username\AppData\Roaming\SongKong
  • Restart SongKong

Oh, it looks like this method worked and SongKong is working properly again! Many thanks to you, Paul Taylor.
