in keeping with what been said. Make sure you aren't using a crack - We don't support cracks or people using pirated software---(no using it)Update GTA IV to 1.0.7.0 (the latest version of the game, or 1.1.2.0 for EFLC) - These patches are needed. (all patches)Make sure that you run the game as an administrator.(doing this everytime)Make sure that your GTA IV root folder (and every subdirectory) is not set to "read-only"Ensure that ScriptHook.dll, ScriptHookDotNet.asi and Dsound.dll OR Xlive.dll are in the GTA IV ROOT folder (all present)Ensure that there is a folder titled 'LCPDFR' in the ROOT GTA IV folder.( Check)Check that all the above files exist, if they do not, reinstall LCPDFR with the MANUAL installation. (did that too)Ensure that you are using up to date versions of every LCPDFR dependency and LCPDFR itself.(check it twice)Install these: https://www.microsoft.com/en-us/download/details.aspx?id=30653 , https://www.microsoft.com/en-us/download/details.aspx?id=30679 Give a clear, detailed description of the problem.
