Sorry don´t waste your time with that - I´ve just checked it out myself.
First inst was Win 7 with Galaxy - Runtime Error.
Second was Win 7 with Offline 104 GB - Runtime Error.
So wrong lead.
But still, where are the needed DX12 installtion files for CP2077 and Win 7 ?
(I have dual boot with Win10 so I could still play, but with uncustomizable Keybindings it´s still a bust
)
