To the best of my knowledge.... As long as your installer is tagged correctly as a 32bit installer by setting the Platform attribute of the Package node to "x86" like this:
<Package Id="*" InstallerVersion="200" Compressed="yes" Languages="1033" Platform="x86" InstallPrivileges="elevated" InstallScope="perMachine" /> [PROGRAMFILES] will resolve to "Program Files (x86)" on 64-bit windows, and "Program Files" on 32bit windows.... This means you can use the value of the [PROGRAMFILES] property when you write to your web.config file. I know that xmlfile and xmlconfig has already been not recommended in this thread, but maybe this wix snippet will show you the light... <util:XmlFile Id="MyMagicId " Action="setValue" ElementPath="//root/node1/node2" File="[MyDirectory]settings.xml" Value="[PROGRAMFILES]" /> Using that... (assuming "C" is where windows is installed) On 32bit windows.... [PROGRAMFILES] will equal "C:\Program Files" On 64bit windows.... [PROGRAMFILES] will equal "C:\Program Files (x86)" This works for me correctly on 32 & 64bit windows. You don't need to know the exact string value of the [PROGRAMFILES] property, you just need to know that it will resolve to the correct "real folder on disk", and always use the property when referencing it.

Subject: Re: [WiX-users] Updating web.config field value depending on if machine's 64bit or 32bit What we are doing is installing sample sites that needs the location of the install as environment variable in web.config to access a file in the appsettings section. However, because our SDK only builds in 32bit, the web.config needs a file location but I need to detect whether to use %programfiles% or %programfiles(x86)% in web.config and I was hoping that during install, we can write some custom action to substitute appropriately. Will ProgramFilesFolder work appropriately? Thanks for all the responses so far.

Subject: Re: [WiX-users] Updating web.config field value depending on if machine's 64bit or 32bit Keep in mind it's better to avoid XmlFile / XmlConfig and just rely on standard IIS custom action functionality, if possible. I don't know enough about your particular scenario to know if it's possible in this case, but if you can throw a [ProgramFilesFolder] into your IIS authoring somewhere instead of relying on Xml modification of web.config, you'll be better off. I know in some cases modifying web.config with XmlFile / XmlConfig Vista will result in slightly unexpected behavior, because the IIS custom action doesn't flush data to disk in 3.0 (so XmlFile / XmlConfig would be operating on the XML file before it was modified by the IIS custom action, even though the IIS custom action was earlier in the sequence). A flush operation was added to the custom action to fix this scenario in 3.5, but 3.5 is still early on and it's hard to recommend it at this point in time.

Subject: Re: [WiX-users] Updating web.config field value depending on if machine's 64bit or 32bit Windows Installer automatically handles translating the ProgramFilesFolder property for 32-bit vs. 64-bit platforms. Are you using an XMLFile element to set the web.config value? Use the [ProgramFilesFolder] property within the XMLFile element, and you should get what you want. - Don Benson - Tribute Inc.
