I'm normally use Wise package studio to create normal windows msi packages.
Now we have to pay for upgrade to support windows 2008 operating system.

I trying to get some feeling with installshield because that's free for us (in combination with zcm).
But how can i see that i'm creating a normal basic msi instead of a installshieldscript msi.
Is it true that i need to deploy extra things (installshield engines) before i can deploy installshieldscript msi's?, and why shall i choose for that one.

I try to get my way into the lot of windows inside installshield / adminstudio.
(WPS was much easier, but there is less development on it)

I hope someone can explain me a bit.
