Can't open the app after install

As the title says, just downloaded the app and once I try to open it I get an error message that says “is not a valid win32 application”. Is there something I’m missing or is there any way to fix this? Tried the installer and the portable version and I still get the same error. I’m using an almost fresh install of Windows 7 64bits.

Hello :slight_smile: Sadly, Karaoke Mugen requires Windows 10 at least. Windows 7 is no longer supported even from Microsoft since January 2020.

Oh, I saw that coming. Not even an old version of the app? I just want to submit some karaokes, so I thought I needed the app to create them and submitting.

Actually you don’t :slight_smile:

If you follow the contribution docs here you’ll only need Aegisub to create the karaoke itself. Then you can submit it via then we can review it and add it or tell you if something’s wrong so you can fix it yourself before we add it.
