In my WiX Bootstrapper Application I want to install a 32bit OR a 64bit MsiPackage depending on the Outlook Bitness. So I search for the registry value (it can be x64 or x86), read it into a variable and set the InstallCondition of each MsiPackage to a string comparison of the variable with the appropriate value.

The result ist unexpected. The string comparison obviously doesn't work.

My Bundle.wxs looks like this:

The installer now writes the following log:

It states:

  1. Setting string variable 'OLBitness' to value 'x64'
  2. Condition 'OLBitness=x64' evaluates to false
  3. Variable: OLBitness = x64

Why evaluates the condition to false while the value obviously seems to be the expected?

How can I write the InstallCondition to test for equality of strings?

Can I use a property and if so how would I do that?

I found examples for RegistrySearches with Result="exists" but not with Result="value".

Thanks for any hints!

Try 

InstallCondition="OLBitness ~= &quot;x64&quot;"

and

InstallCondition="NOT (OLBitness ~= &quot;x64&quot;)"

the OLBitness variable is a "string" variable and I think the x64 might get picked up by the parsing as a int represented in hex or something?? Then when it tries to convert the string to an int it converts it really wrongly so they never match.

You can debug this but it takes a while to set up. I had to do this for when I was trying to compare versions. When you use a registry search the variable type is always string. The condition.cpp in the engine vcproj from wix source is smart enough to try and convert a string variable to another type (numeric, version) then comparing. And it turns out I just spelled the variables name incorrectly......

Anyways, you could also add 

<Variable Id="x64Bitness" Value="x64" Type="string" />

to your Bundle and then in the install condition compare it to x64Bitness instead of "x64" and that would force string comparison.

  • Thanks a lot! Comparison works with the `"`and with the Variable. Btw a little annotation: Variable has the Attribute `Name` instead of `Id`. What is the meaning of `~=`in contrast to the simple `=`? In practice I see no difference. – Heiko B. Apr 25 '16 at 08:28
  • ~= just compares strings case insensitive. It's almost always better to compare strings ignoring the case when you don't control one of the strings unless you know for sure you want to take the case into consideration (like a CD-key or some URLs). I guess the idea is you don't know for sure whether or not version X.Y of Outlook puts the registry key as value "X64" or "x64" and if it ever does use a capital X, if you don't use "~=" you won't match the variables.
