Hey everybody, I have been using WinInstall LE 2003 since a few months and it is working fine. I can create MSI files and modify them. But you have to know what you are doing otherwise your package will not work. Here are a few things I am modifying; - Removing HKCU entries, - Changing installation method to per machine. Important ! - Program Shortcuts ( Uninst.exe, do not need this file) - Removing unnecessary captured files ( Explorer --> Comdlg32) - Removing captured WinInstall entries. - I am also checking the files that will be copied. ( Any dll files overwritten ! ) - Installing the MSI file with start /wait / i /qb+ or /i /qn switch. - Except above, A few MSI rules; - The highest version of the file always wins. - A file without version number considered as user data. - For those who is intended to modify the MSI package, I suggest to read Windows Installer WhitePaper from Microsoft to get a familiar with this technology.
