I have GTA IV and EFLC installed on my PC thru Steam. Both run properly before downgrade and mod install. I downgraded to EFLC 1.1.2.0 and successfully installed LCPDFR 1.1 (installer, no ads). Install set to Dsound.dll, no xlive.dll in EFLC folder. Diag tool passes 100%. Folder and all subs/files NOT set to read-only. First run of GTA IV EFLC a Windows installer ran for Games for Windows live and only gave UNinstall option to remove. EFLC run as administrator gives game window to cancel or play (with old create account text above). I click 'play' and get System error because Xlive.dll not found. Deleted dsound.dll, reinstalled LCPDFR with Xlive.dll, Diag tool passes 100%. Run as administrator, click 'play' and get FATAL ERROR: VDS100 (invalid resource detected). Support.Rockstar suggests uninstalling any/all MS Games for Windows Live (Marketplace), etc. Uninstalled and tried to run EFLC with dsound.dll and xlive.dll alternately. But No Go. They also suggest installing .Net Framework 4 but if you try to install the currently available 4.5 in Win10 it just tells you its already part of the OS and you can only close the window. There have been several Win 10 updates since I last ran GTA IV and EFLC, so perhaps a factor. Idk. Help Please :)
