Project64 - specified executable is not a valid applications for this OS platform ERROR

[JimboJambo86]

Hi there, recently made the switch from Hyperspin to this and loving how easy it's been to set up... But I can't get project64 to work in LaunchBox, I'm receiving the error:

"An error occured while trying to launch the game: The specified executable is not a valid application for this OS platform"

But this can't be right as I can run project64 fine outside of LaunchBox, and if I right click a game within LaunchBox, and select open Project64, the emulator opens up and I can play a game from the list within project 64 fine.

I first installed LaunchBox to a different location but moved the folder to a different place and that includes all the emulators and ROMs, I did update all the paths for the ROMs and emulators. Others are running fine since. I'm hoping I'm missing something simple and obvious!!

Thanks in advance.

Ive managed to solve the issue by reinstalling Launch Box, no idea what was causing it but figured it was a simple fix i hadn't yet tried.
