From the customer support:

I am testing SENDBLASTER at a NOTEBOOK with Microsoft VISTA. It presented an error “Some DAO libraries were not found on your PC. Please download….”.

I download, and installed. It did not work. Uninstalled, cleaned registers, made a new sendblaster instalation, rebooted, installed DAO35SETUP againd and I continue receiving same message…

This is a common error among SendBlaster installation on Windows Vista, because SendBlaster must be installed and used with User Account Control enabled on Windows Vista operating systems.

To resolve this DAO35SETUP error please follow these instructions:

1. Uninstall SendBlaster (from control panel)
2. log in as administrator (Vista privileges setup)
3. Enable Vista USER ACCOUNT CONTROL (UAC)
4. Install SendBlaster
