thnx totoymolo, but im not looking to download any software just to build a batch script, waste of harddrive space
The softwares there are REALLY small and don't need installation.
You missed the point of using the tool
Windows Installer Command-line Builder. It doesn't just build the commands for you, but it also lets you see all the availabe public property of your msi.

and if all newbies use programs like these to build their scripts they never actually learn how to build a batch or similiar, they have programs do it for them.
I totally understand what you mean. You want to do it the hard way, just like what I did.

But give at least the command line builder a try and play with the properties. You will understand what I mean.

Hey, I'm a newb too!
And another thing is, I don't think you can see ALL the available public properties (and of course even the hidden properties!) of an msi without using a software. Like I said on the other thread, not all msi's are the same. So they don't have the same properties. I understand that you don't wan't to install another software just to do this, but unfortunately, there is no way for that (or at maybe I'm just not aware of it..)
Just for info, the PIDKEY or PRODUCTKEY are properties. And not all msi's use them. Every developer can create their own properties so you can't easily guess what they are.
By the way, did the PIDKEY or PROODUCTKEY worked?
