I went to install LCPDFR, hit browse and put it into the GTA 4 root folder and clicked install and it came up with this:
Installation component 'LCPDFRModels' error'd!
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.File.InternalCopy(String sourceFileName, String destFileName, Boolean overwrite)

It said to put this on the forums to get help. I have read over the support guidelines multiple times and I have everything.
