Very early user of LaunchBox here. 
 

every time I try to launch a ROM, I get multiple RAHasher.exe related errors. The rom will eventually open, but I’d like to avoid this going forward. 

im running an AMD Ryzen 7 x64 cpu

any advice?

So after the previous LaunchBox update, the NES ROMs were launching just fine.

However, after the latest LaunchBox update, I'm getting the same RAHasher.exe errors when trying to launch CHD roms.

Any ideas here?

Looks like your system doesn't have the Visual C++ runtime installed that it needs. You can download it from the following link and then run the setup to install it.

Thanks for the reply.  unfortunately, i already had it installed.   i repaired it using the link you sent, however, and i'm still getting the above errors.  Any other ideas?

Can try an OS repair. Open up command prompt AS ADMINISTRATOR and then run "DISM /Online /Cleanup-Image /RestoreHealth" (without the quotes) and let that run. After it's done then run "sfc /scannow" (again without quotes) and then when both are done restart your computer and see if that corrects it.

here's a screenshot of the completed cleanup/scan.  restarted and still getting the RAHasher errors 😞

Really frustrating as I thought LB would "just work" and not sure what to do here.
