>> I tried setting the Platform target of the custom actions project to x64
That should do exactly what you want. When you have set that, can you check the build logs to see whether it is getting sfxca.dll from Program Files (x86)\Windows Installer XML v3.5\SDK\x64 ? The relevant logic is on line 87 of wix.ca.targets: <CreateProperty Value="$(WixSdkX64Path)SfxCA.dll" Condition=" '$(SfxCADll)' == '' and '$(Platform)' == 'x64'"> <Output TaskParameter="Value" PropertyName="SfxCADll" /> </CreateProperty> -Jason- -----Original Message----- From: Stelios Kyprou [mailto:stelios.kyp...@formicary.net] Sent: Tuesday, June 29, 2010 9:53 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] sfxca.dll 32 and 64 bit version in visual studio 2010 (wix 3.5) Hello wix users! This is my first email, so if i do something wrong, please bare with me (but DO tell me ;) I have a situation where i'm really stuck and want to do things the right way: I use Wix 3.5.1811.0 in visual studio 2010. Skipping the basic configuration stuff, i create a "c# custom action project" and add my custom action in there. That custom action project uses a dll that is 64bit I then use it properly in my .wixproj by referencing the customaction project. The question is: When i build the C# custom action project, it grabs sfxca.dll from C:\Program Files (x86)\Windows Installer XML v3.5\SDK\x86 instead of C:\Program Files (x86)\Windows Installer XML v3.5\SDK\x64. Thus, when i build the msi and run it, in the logs i get a BadImageFormatException and the installation fails. I did a hack, where i just replaced the sfxca.dll in the X86 folder with the 64 bit version, rebuild, and the installer runs fine. But OBVIOUSLY this is not acceptable. How can i configure the project to use the 64bit version of sfxca.dll which is under C:\Program Files (x86)\Windows Installer XML v3.5\SDK\x64 WITHIN visual studio? -I tried setting the Platform target of the custom actions project to x64 : No positive results. -Under the "Build" tab in the custom actions project properties, the Configuration is set to "Active(Release)" and Platform to "Active(x86)". I have No other available options under Platform. -Informationally, in the .wixproj, Product/Platform is set to x64 (for a 64 bit installer). Any suggestions would be appreciated!
