Error LS-0019-IS-PQR1603

Hi, I am stuck here too. No win64 folder to be found, only win32, so I can’t add the “-skipbuild…” or any of the other suggestions found when searching for this. The launcher properties points to the win32 folder. I have double checked and yes my win is 64bit. Have checked .net and it is updated. I have uninstalled and installed 3 times. On my computer at work, all just worked first try. But at home I can’t get passed this.
I also did try to make a win64 folder manually, copy all content from win32 folder (just to try), didn’t work.

Any ideas out here?
