Thanks for the suggestios, brothers. I would definitely like to try Innosetup, Installrite or any similar software as suggested. But as on now I prefer to use winrar as I believe that it has better compression ability than other installers. Well, I might be wrong as I didnot give enough tries to other options. PaulIA, I am sorry that I couldn't make you understand my question. Yes, my SFX file unpacks itself to %programfiles%\portable but then it does not install anything but runs my application directly from there. I know about "TempMode" of winrar, but I don't want to use that for this particular exercise because I don't want to get my foder deleted automatically after the extraction, but later when I decide to remove this softwre from my machine. I can do this manually also, deleting the foder and deleteing the registry entries, but I want to make a quick way of doing that like making a batch file or a macro???
