strysearch-variable-always-false)
I want my install to fail if a third party software element is not
installed. I added a `Fragment` with a `util:RegistrySearch` and a
`bal:Condition` to the `Bundle`, but I can't get it to work.
`ThirdPartyCOMLibraryInstalled` never evaluates to true. I've confirmed
that the key exists, and the value I use for `Key` is correct - I
copy/pasted the name from the selected key in regedit. There are no errors
in the log.
I'm building the installer with WiXTools 3.7 in VS2012 on Win7 64bit and
testing on both WinXP SP3 and Win7 64bit.
Searching online for other examples for `util:RegistrySearch` I ran across
the following alternative forms for the condition test expression.
1. `ThirdPartyCOMLibraryInstalled = 0` - always False
1. `ThirdPartyCOMLibraryInstalled <> 1` - always True
Here is the `Bundle` code:
