I don't know if this will work, but did you suppress modularization on the MYPROP variable in your merge module?
BTW, if I can make a plug: if you can get away with using WixLibs instead of MSMs they are much easier to work with, much more flexible, easier to understand, and tend to be less buggy. -----Original Message----- From: Sudripta Nandy [mailto:sudrip...@sarangsoft.co.in] Sent: Thursday, August 05, 2010 5:12 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Changing a main module property value within a merge module custom action Hi, In my setup project, I am having a main module and a merge module. I have a property called 'MYPROP' declared in the main module. I need to do some operations in the merge module's custom action and depending on the operation result, I need to set the value of 'MYPROP' to '0' or '1'. I am able to get the property's value correctly within the merge module's custom action using MsiGetProperty. But, when I try to change that value 'MYPROP' within that custom action using a call to 'MsiSetProperty' it doesn't get reflected within the main module. The main module still has the old 'MYPROP' value. Is there any way in which I can change a main module's property value from within a merge module's custom action? Thanks.
