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

32bit-64bitwindows-installerwix

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?

Best Answer

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".

How to add a WiX custom action that happens only on uninstall (via MSI)

EDIT: Perhaps look at the answer currently immediately below.

This topic has been a headache for long time. I finally figured it out. There are some solutions online, but none of them really works. And of course there is no documentation. So in the chart below there are several properties that are suggested to use and the values they have for various installation scenarios:

So in my case I wanted a CA that will run only on uninstalls - not upgrades, not repairs or modifies. According to the table above I had to use

<Custom Action='CA_ID' Before='other_CA_ID'>
        (NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")</Custom>

And it worked!

.net – Oracle.DataAccess.dll’ targeting ‘AMD64’ is not compatible with the project’s target platform ‘x86’ when creating a msi package

You need to get the x86 oracle client, then you can use all x86 components. Or you need to fix the compile to compile in x64, then you can use all x64 components.

Or you could try setting the importing of dependencies to off within msi, which might work, but I don't recommend it.
