I have a working installer and have been using this installer for both 32-bit
and 64-bit, simply switching the "Program files" location, i.e.:
<?if $(var.Platform) = x64 ?>
<?define Win64 = "yes" ?>
<?define PlatformProgramFilesFolder = "ProgramFiles64Folder" ?>
<?else ?>
<?define Win64 = "no" ?>
<?define PlatformProgramFilesFolder = "ProgramFilesFolder" ?>
<?endif ?>
We just discovered that Weird Things Happen when both the 32-bit and 64-bit are
installed, then uninstalled in various orders, etc.
The files in "Program files" are obviously installed in separate locations, but
some of the content is installed in the same location, i.e.
"CommonAppDataFolder".
My question is, to save myself the most amount of pain in the future, which
Guids should be the same between the 32-bit and 64-bit versions, and which
should be different? For those that are different, how can you code this in WiX
without maintaining two completely separate installers? We would like to
support both major and minor upgrades, and although we don't want people to
install both the 32-bit version and 64-bit version and run them side-by-side,
it is really outside of our control and ideally that shouldn't break anything,
nor should uninstalling one version break the other.
Here are my guesses so far, but I really don't have much confidence in my
understanding:
+---------------------------------+---------------+-----------------------------------------------------+
| Value | x86/x64 same? | How
|
+---------------------------------+---------------+-----------------------------------------------------+
| ProductCode No Use * as ProductCode
|
| UpgradeCode No Define different static
Guids in config file |
| Files in "Program files" No ??? Would I have to define
every single file twice? |
| Files in " CommonAppDataFolder" Yes Hard-coded Guid
|
| Shortcuts (shared) Yes Hard-coded Guid
|
+-------------------------------------------------------------------------------------------------------+
Please enlighten me! Thanks!
Dave
