It appears that you are using the WixStdBA, in which case you could implement a BAFunctions.dll. There is a sample baFunctions.dll in the wix source zip package that provides the details with examples. Also this old thread <http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/is-there-a-way-to-set-a-variable-by-selecting-a-different-radiobutton-in-BURN-td7587887.html#a7587889> provides more details.
A better long term choice is to implement a mba, and then you can do most anything that your managed language supports. The wix source includes the mba used by the WiX toolset, which can be used as a reference, but is not really a tutorial. I can't think of a way to achieve your goal without using a BAFunctions.dll (for WixStdBA) or an mba. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Burn-prerequisite-4-numbers-warning-message-before-installation-tp7600556p7600676.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
