This is a duplicate of what I posted on Discord earlier. Is it preferable to post bugs here?

Unless I launch Pixel Composer as admin (which I guess is bad habit) it won't start. I got this from Event Viewer: Faulting application name: PixelComposer.exe, version: 1.16.9.2, time stamp: 0x66176084 Faulting module name: libfilesystem.dll, version: 0.0.0.0, time stamp: 0x6449b58a Exception code: 0xc0000409 Fault offset: 0x000000000003da28 Faulting process ID: 0x0x54FC Faulting application start time: 0x0x1DA987EED1B88E5 Faulting application path: C:\Program Files\PixelComposer 1.16.9.2 itch\PixelComposer.exe Faulting module path: C:\Program Files\PixelComposer 1.16.9.2 itch\libfilesystem.dll

It seems you open the file from a protected (C:) drive. I’d recommend moving it to another drive (or desktop) and try again.

Thanks, will try. Installed the Steam version, too, which is working fine.

mismo problema, con Steam y con ejecutable y con betas no he podido hacerlo funcionar
