Thank you very much for reporting your problem !
"Coolector Movie Database works only with Windows XP, Windows Vista, or Windows 7"
Coollector reads your environment string and determines your OS from it.
I have build a special version for you:http://www.coollector.com/Coollector_test.exe
This version will display your environment string, and I'll be able to understand why the program didn't recognize Windows Vista.
Also this version will generate a crash dump to help me understand why the program crashed. Please send me the .dmp and the .xml files at this address:hector at coollector dot com
