Software Deployment

I'm confused...

If you're not allowed to use the command line, how is it that you're calling the set-up stub? Clearly you are doing that, since no MSI I know of will natively read and use XML files for configuration data. Then you mention a transform: so you now have an MSI?!?

I mean to say : I have to pass properties by which installation will be done without any problem, but I can not pass them through commandline.[Commandline should be calling only msi and mst]
My properties are like below.
e.g. A = <path to config.xml>
and I can not use hardcoding in my msi. If I have to pick those xml files from sourcedir, then what are the options available for me?
1] I can use vbscript, in which I can use sourcedir property and can resolve <path to config.xml>
but if any easier or simpler method is there, then I will like to go for it.

Why not use a 'Set Property' (i.e. a type 51) CA in the Execute sequence which uses SOURCEDIR as part of its path, then use the resulting property to point to the XML file?

anything you pass on the command line will be the same as a property in a transform. (except they will be retained during heal)

properties on the command line are fail anyway.

Also in response to VBScabs post SOURCEDIR may also require the use of the ResolveSource action as well.
