Subject: [WiX-users] Dynamic installation path based on registry variable
I am sure this is very trivial question nevertheless I was unable to find an
example or any kind that would clearly illustrate how to change the install
path based on the combination of conditions.
I am trying to install a module that should work with several versions of
the product X. Product X exist in several versions and changed its name over
the time of its existence. The problem is that name change of the product
also changed the registry key name which I was reliant on in the past. So
now I need to check whether my user is about to install my add-on for
product X on the system with an pre-renamed version (Registry Path A) or
post-renamed version (Registry Path B)... Naturally I case search the
registry for two separate location, what I can't figure out is how to supply
end result to the child directory of the TARGETDIR? In the snippet of code
that I've attached below I've marked the "problem" spot as " V1V2_DIR or
V3_DIR"...
Do I user some sort of the custom option? Can I use <?if?> statements?
All I need is to express is something like this...
IF V1V2_DIR != NullOrEmtry
var.Something = V1V2_DIR
ELSE
var.Something=V3_DIR
How do I do that? Thanks for your help!
