iVault Installation fails

I have tried a few times to install iVault, and InstallShield always fails with error 1628: Failed to complete installation. I have comodo Firewall and anti-virus installed. Although disabling them doesnt help. Also the files in the iVault installation package are fairly old (2001) - could there be some inconsistency with latest Windows versions? I am using Windows XP SP2.
have same problem with installing Backup.
