I know there is an API in latter versions of Wix. It was discussed on this mailing list or wix-devs. Can't remember the name and don't know if it's documented to not.

I'd check if environment variable %wix% is present. If yes, check e.g. for fileversion of %wix%bin\candle.exe.
Other approach is traversing the ARP information in
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
(or without wow6432Node on x86 OS)
for the GUID {65E893AD-EDD5-4E7D-80CA-F0F50F383532}. The so found key should be the WIX ARP Entry. If present check for BundleVersion.
