Yea, this is the Problem. The version is 188.8.131.52. I used the latest 3.5 build of WIX.
I tryed to build the 2008 installer but VS throw an error:
<WixVariable Id="WixUICostingPopupOptOut" Value="1" Overridable="yes" /> is defiend 2 times in the Project.
Which Wix version i should use for this version?
Thx a lot.
