I just downloaded the EpicGamesInstaller launcher from the official website but ran into error 1310 “error copying files” whilst running the launcher. I ran the msi installer with admin privileges from the command prompt and also gave toggled full permission for the target installation folder but none of these solutions worked. Also tried uninstalling and reinstalling Microsoft Visual C++ 2015 Redistributable (both x86 and x64) and no luck so far.
