is it possible to create a single installer for both 32 & 64Bit installer?

Hi,

Is it possible to create a common installer for 32Bit & 64Bit environments? if yes, will it increase the size of release media? Is it possible to do this in Basic MSI project?

A 32-bit Windows Installer installation can successfully install on 64-bit systems, but only to 32-bit locations. If you need to support 64-bit locations and 32-bit systems, you either need multiple Windows Installer packages (see Heath Stewart's blog posting on that), or you need to use an alternate technology (such as InstallScript with conditional code).

Hi MichaelU,

Thanks for your replay. Can you give any links for verification regarding to my question?

I'm not sure I understand your followup question. The blog post I referred to should be high in the results for this search: http://www.google.com/search?q=heath+stewart+multiple+packages

You can, of course, use a single Basic MSI Project to generate the separate 32-bit and 64-bit packages using Release Flags to include/exclude features as appropriate for the particular platforms.

I am doing this in my basic MSI installer package but still get the build error -5008, "Intel64 or AMD64 must be specified in the template of the Summary Stream" when I try to build the 64-bit version of the install. Thoughts? Any help is greatly appreciated.
