WACUP 1.99.54.24960 crash
« on: August 31, 2026, 11:36:43 PM »
Hello,

I've inexplicably started experiencing WACUP crashes with the 1.99.54.24960 64-bit WACUP build. Any time I try to change songs, or the current song finishes and it tries to go to the next song in the playlist, it hangs and then closes. As far as I can tell, it is not saving any crash dumps because I see none linked under the Advanced -> Error Reporting. I tried using the ProcDump button in the UI as well as running `wacup.exe /procdump` in a CMD window, but it doesn't restart when clicking the button and wacup doesn't launch when trying to run from CMD.

I tried uninstalling and reinstalling, but it seemed to remember the playlist/song information when I started it back up after a new install, so the clean install instructions I found didn't clear everything out as I expected. Are there official clean install instructions somewhere I can follow to try and resolve this, or some other way of trying to capture a crash dump or other diagnostic info?

Thanks!

Is it the x86 or x64 build type? Also what version of Windows are you using & does making a portable test install via the installer modes make any difference to how it behaves? Otherwise the simple option is to go to preferences -> plug-ins -> output -> select notsoyasapi from the dropdown if notsodirect is the selected one & if notsoyasapi is the selected on then change the selection to be notsodirect.

If the action to restart or manually run via the procdump mode isn't working at all then that makes me assume the OS is getting in the way of things or procdump can't be obtained or there's a dependency loading issue which is causing the failure (something I'm not seeing).

I don't know what clean install instructions you were trying to follow but if the uninstaller is used then it prompts whether to keep the settings folder or not otherwise it'll do what it can to remove the whole program folder (assuming this wasn't a portable install anyway) & will indicate if there was anything left (not that it should typically relate to settings persisting). Am also assuming it's wacup's resume mode being used & not from a 3rd party plug-in which can & often will use the OS registry so isn't something that the uninstall knows about.

I'm using the x64 build. I tried switching from notsodirect to notsoyasapi and the behavior was the same. I did uninstall via the installer and selected remove profile info, but when I reinstalled a non-portable install it launched remembering the playlist + current song + current song time. I'll try again and see if I missed something, and I'll try a portable install to see if that changes behavior. Thanks!
