All you need to do is test for the existence of a property because a blank value means the property will not exist. Installer will delete a previously-existing property if its value becomes blank and will not create a new one with a blank value. So in this case, just change the condtion to this: <Condition Message="You must have the Rendering Service installed first.">RENDERINGINSTALL</Condition> BTW, the way to test for the negative of this condtion (in other words, a property *with* a value) is to simply use "NOT" in front of the property. So it would be "NOT RENDERINGINSTALL" if the requirement was that the rendering install not be installed first. -- View this message in context: http://n2.nabble.com/use-of-Condition-to-detect-Property-tp1213384p1227839.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
