Error on Build Lighting - missing UnrealLightmass-Core.dll

Whenever I try to build lighting on my level, I get this error message. “The procedure entry point ?StringHasBadDashes@@YA_NPEB_W@Z could not be located in the dynamic link library UnrealLightmass-Core.dll.”

I tried to verify the install and that didn’t solve the problem. I’d rather not do a full re-install if I can avoid it. Has anyone heard of this error? Thanks in advance!

Hello Robert,

Thank you for your report. I know you do not want to un/reinstall, but have you tried deleting the editor files and downloading the editor from the launcher again? If that file is missing, then it will have to be downloaded again properly.

Cheers!

Thanks, I resolved the issue by deleting the engines lightmass core files and letting the launcher verify install and reacquire the removed files!

Hello Robert, I have the same issue.
Could you please explain me how do you actually made it?

Thanks.
