Thought I would update this as I have had some joy getting it to work.
Basically, Vista compatability is enabled with CRXI R2 Service Pack 2.
HOWEVER....
Even though I had fully upgraded and confirmed that I was indeed running CRXI R2 SP2 I still couldn't get it to function on Vista (worked fine on XP).
I was using the 'prerequisite' method in the setup project. Mucking around to day I tried the merge modules approach and found out that I prefer this method anyway (I have had trouble with Crystal Reports installing itself as a seperate application). Got excited..installed..but still not working on Vista.
So I decided on the off chance to download the latest merge modules from the Business Objects site. You know, I figured that SP2 would have updated these....but no.
Having upgraded from the existing merge modules to the downloaded ones, the app finally works perfectly on Vista.
Which is a relief.
Jon.
EDIT:
Still one slight issue, not major, but since adding the merge module I get 188 Warnings about...
'Two or more object have the same target location.' and then various file names.
I can't work out how to get rid of it. I have only added the one merge module (CrystalReports11_5_NET_2005.msm). Still builds and installs but if anyone can explain this it would be appreciated
