can someone try to explain it maybe?

Windows Installer has it's own built-in version checking. If you would like to leave an older version behind if present, you will need to manipulate the entry in the component table a bit. You would need to take whatever integer is in the attributes column of the component in question and add 128 to it. Check the 'Component Table' topic in the Windows Installer SDK for more information.

I re-read your question and I think I have a new answer for you. :-)
You will need to check the file version using the Signature and AppSearch tables. You could also use a VBScript custom action to get the version of a file and populate a property. You could then add a condition to the component that checks that property against whatever value you need. Sorry I misread your question the first time around, but I hope this helps you.
