It came to my mind this idea since there is no way to check installed version of a program, only if a file is present. Maybe you could add a way to check against MD5 checksums, so that way we could know it a desired version of a program is installed.
Thi idea came to my mind when I was choosing programs to install and couldn't remember is Internet explorer 9 was installed or not and since it's a program that comes with the OS, you can't use the check for exe file present...
I hope you can add this feature or something to do the same thing. Also a good thing would be to be able to determine Windows Version so that way we can set different ini files depending on which OS is installed.
Thnxs in advance for all and hope you can do something about it
