I would recommend using the DTF "wrapper" for C# (or any other .net) custom actions. If your C# code is AnyCPU you won't need to worry about bitness for the CA code itself using DTF.
Otherwise, 32-bit CAs work in all 64-bit systems that have WoW64 present (see http://blogs.msdn.com/heaths/archive/2009/11/06/wow64-is-optional-in-windows -server-2008-r2-server-core.aspx). Know that 32-bit code in a 64-bit system may have to use WoW64 APIs to "see" some things you may wish to access when it runs. -----Original Message----- From: Sagar1111 [mailto:sagarkavitak...@gmail.com] Sent: Tuesday, December 29, 2009 11:16 PM To: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Creating MSI for 64bit machine Thank you very for the quick reply Rob and Michael. I have a custom Action written in C# which is being used in the MSI. So do i need to build that custom action separately for 32 bit and 64 bit and then use those specific "CA.dll" files for respective MSI -Sagar1111 Rob Mensching-7 wrote: > > candle -arch will switch the Package/@Platform to 64-bit.
