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

(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.
