The question was really what is the correct syntax for "variable not equal to
empty string" when used with DetectCondition? (I don't think the syntax for
this is documented so will add it when I know the correct syntax.)
Some options:
Variable <> ""
Variable != ""
Variable
NOT Variable = ""
Or something else.

You want DetectCondition. InstallCondition says whether a package should be
installed on the machine. If false and the package is installed, it will
uninstall the package.
