InstallAware

I'm trying to change the product code at compile time but having a little trouble. I first tried passing a compiler variable PRODUCTCODE={blah} (with correct replacement of the blah). That had no effect. So I passed the same compiler variable and made one of the first lines be which effectively changes the product code. However, the NEEDSUPGRADE variable is set as if the previous product code was used.

Is there an easy way to change the product code at compile time or very early in run time but before other variables (like NEEDSUPGRADE) get set?

In case anyone was wondering, I did figure out my problem. Go to the visual screen -> Application Information -> Project Properties and set the product code field to "#USEPRODUCTCODE#" (without quotes). A tool tip bubble might complain at you but you can ignore it. Then set a compiler variable named USEPRODUCTCODE to the GUID you want to use. Don't do anything in the code section.
