Hi, It's down to the architecture of your software and the needs of your users. Typically you only offer the correct msi per bitness as for most people there is no reason to have both. If you have a lot of plugin developers that will be struggling to keep up and make 64bit versions for your software then you may indeed want to offer then the ability to have both versions installed. This may add complexity that a standard user may find confusing though.
The potential dangers lie in the application itself, if you use any shared resources, com objects, registry keys etc. you may have problems installing both side by side as they will clash. The wow64 system can work quite well at isolating some of this for you. But it may also not be what your users expect if they want to switch between bit versions and have their settings etc. be synchronised. You will only know for sure if you do some testing.

Thanks for your input Daniel. I all ready have two seperate MSIs for each bitage, and they currently share a ProductGUID to prevent any user installing both, but I'm wondering if this should not be the case and that users should be allowed to install both - as seems necessary fot photo editing apps (or anything with 3rd party plugins, I guess). I can see that a different named shortcut would be required to prevent them clashing, for example. But is there any actual harm in offering both? -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Should-you-inst all-32-bit-and-64-bit-versions-os-the-same-application-tp7578776p7578780.html Sent from the wix-users mailing list archive at Nabble.com. ----------------------------------------------------------------------------- - Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
