InstallAware

First, thank you in advance for answering this question.

I have developed a VB6 application on an XP machine. I need to create an installer that will potentially install this application onto an XP machine or a Vista machine. Installing onto a Vista machine requires more files to be installed because there are many system files that Microsoft did not ship/include in Vista.

So question one becomes, when I develop my IA install package on my development machine, which is XP, how do I determine which files need to be installed on the target platform (XP or Vista)?

The second question becomes, within IA how do I specify that "this" file should be installed if installing on a Vista machine, but don't install "this" file if installing on a XP machine?

Thank you very much,
Michael Carr

Your file requirements are going to be largely determined by your own application. What files does your app use that came with XP, but no longer come with Vista?

Are you sure that they are system files? Some of the files that were installed under previous versions of Windows were support files for older applications. Raymond Chen had a good post about that on his blog.

Michael,

You can check for the OS of the target PC with the Get OS or SP Level command. Based on conditions you can install some files, and others not.
