Using an absolute value in a .net installer

I'm using WIX files to build an MSI package.

It works using an environment value

<Property Id="ProgramFilesDir" Value="$(env.ProgramFiles)" />

but doesn't seem to understand absolute values, e.g

<Property Id="ProgramFilesDir" Value开发者_高级运维="X:\MyFolder\" />

Is there anywhere else I need to declare absolute values?

You shouldn't be using your computer's paths, as no one guarantees, for example, that the target machine is going to have drive X at all. Instead use the built-in paths, like so:

<Directory Id="ProgramFilesFolder">
