X86_64 libraries will not load

When I load the x86 libraries, roms play without problems. But when I choose the 64-bit version I get an Error 1 and return to GUI. This goes both for SNES, Genesis, Atari etc

On the laptop with Windows 7 64-bit I have no issues, but when I installed Windows 7 64-bit on the desktop I get this error

is there any missing library I have to download?

thanks

No, you don’t need anything extra. Are you sure you’re using 64-bit RetroArch? The “bitness” of the libretro cores and the RetroArch executable need to agree.

Also, does the log show anything useful? It would be at the very end.

probably had to do with the fact that retroarch (both 32bit and 64bit) was on the same folder in an external hard drive. while the laptop had no issues since it is there where I installed it first, the desktop did not recognize the 64bit libraries.

I installed Retroarch again in separate folder for 32 and 64 bit to avoid confusion and problem solved on the desktop.

thanks

Good deal. I’m glad you got it worked out.
