I installed Windows 8 on a second drive and made a Junction for Steamapps so Steam on Windows 8 could access all the 100+ already downloaded games from Windows 7. This almost worked, but each and every game wants to validate and/or redownload files if I try to launch them, and my "installed" list acts as if these games weren't there at all.
I have full access to the Windows 7 partition which "knows" which games are installed--how can I either copy files from Windows 7 or otherwise force Windows 8 steam to realize it's already got all these games downloaded?
Steam.exe
and thesteamapps
folder Steam will recheck installed games.
