Thank you for your reply. I’ve installed UE 4.9 in another directory and can open UnrealPak.exe correctly. But when I opened UnrealPak.exe in my 4.12 binaries/win 64 folder, it fails.
Before that unrealpak.exe fail error appear, an error about “missing api-ms-win-crt-convert-l1-1-0.dll” error appears. So I downloaded that dll and put it in binaries/ win 64 folder.
The dll error no longer appears and the UEPak error appears.
I have also installed 4.9 in another directory is there a way to copy some files from that 4.9 directory and replace them into 4.12 directory to solve that UEPak error?
Thanks.
