Can't complete installation of 2007 version due to error message 1722

This problem relates to the MSI installer from Microsoft; it is associated with either an outdated or corrupt Windows Installer or with permission for Windows Script Hosting (WSH).

First of all, download the latest version of Ad-Aware from the Support Center or https://secure.lavasoft.com/products/ad_aware_free.php and reinstall. You may also update the software from the 'Web Update' menu in Ad-Aware 2007. Click the 'Update' button to connect to the update server and download the updates. Restart Ad-Aware and Ad-Watch to activate the changes.

CONFIGURING WSH PERMISSIONS

Warning: Do not try to edit registry keys if you are unfamiliar with the Windows Registry. Attempt this only at your own risk; Lavasoft does not take responsibility.

• In the Windows Start menu, open run and type 'regedit' in the command line. Click 'Ok'.
• Check for either or both of the following registry keys:

HKEY_CURRENT_USER\Software\Microsoft\Windows Script Host\Settings\Enabled
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows Script Host\Settings\Enabled

If either of those has a DWORD value of '0', then scripting is disabled. Changing the values to '1' should enable scripting.
