Is it possible to target x64 .msi with WiX on a 32bit machine?

Question

I'm developing SharePoint solutions on a virtual 32bit machine, and I use Wix to package the setup.

I'm targeting both 32bit and 64bit environments with my solutions, but in order to create 64bit MSI's, I need to have have a 64bit machine and the 64bit version of WiX. Normally, this wouldn't be an issue, since I would have just simply use a 64bit dev environment.

But there are some issues with developing SharePoint solutions on a 64bit platform, which more or less forces me to develop on the 32bit platform. Because of that, I can't create a 64bit MSI's, unless I copy the source files to a 64bit machine just to build the 64bit MSI, which feels a little bit cumbersome.

Is there any trick to flag/build the 64bit MSI package on my 32bit dev box, if it's even possible?

Answer 1

You do not need to run a 64-bit development machine to create a 64-bit MSI file.

What makes an MSI file "64-bit" is simply that the "Template Summary" field in the Summary Information Stream is set to "AMD64;1033" (one possible example) instead of "Intel;1033".

AFAIK Wix工具集与平台无关，你需要安装x64版本 ，你需要在设置中使用正确的标志（有很多地方你需要明确x64，更多信息在这里 ）。
