I agree with Peter. To be able to have tight control over these kinds of scenarios, I designed our 32-bit installer to explicitly prevent itself from being installed on a 64-bit O/S (using a simple launch condition). I then designed our 64-bit installer to install support for both 32-bit and 64-bit applications that use our product on a 64-bit O/S. That way I do not have to worry about compatibility between the 32-bit installer and 64-bit installer - I can deal with 32/64-bit compatibilities in the 64-bit installer alone.

Subject: Re: [WiX-users] Should you install 32-bit and 64-bit versions os the same application? There's no harm I can think of in offering both but you have to be certain that your application (and any third party add-ins) aren't contending for system resources which could result in data corruption or undesired behaviour. For instance, would both versions overwrite the same user settings file ? or might they try to configure IIS in conflicting ways ? What happens if one version is upgraded, updating a common dll but the other version isn't - is the new version going to be backwardly compatible ? Things that were single instance now become multi-instance and your application needs to be able to handle it. Windows' keeps some parts of the 32 and 64-bit worlds separate for you but not all. -----Original Message----- From: Gareth [mailto:gmor...@serif.com] Sent: 12 June 2012 16:32 To: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Should you install 32-bit and 64-bit versions os the same application? 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.
