Error 1722 is not an Ad-Aware error, but rather the MSI installer from our friends at Microsoft. This has affected other products as well.
See
this for some ideas on solving it.
tried all of the above drove myself absolutely mad with it (i do of course appreciate the fact you took the time to try to help me out) but i think i will never get the program (ad aware 2007 free) to instal and i think i will therefor look elsewhere for an adware program that will install!!!!!!!!!!!!!!!
