Decided to install WISE 2011 on other (Vista HP 32bit) laptop, since WSA didn't appear to be accepting license key as per : https://www.wilderssecurity.com/showpost.php?p=1972869&postcount=2 And sure enough, once WISE was installed and activated (without fuss albeit a lengthy install) with all updates enabled, it prompted to download and upgrade to WSAE. But when WSA tries to install I'm getting a message that DEP is stopping it, despite having DEP only enabled for basic Windows progs etc. Also, despite running as full admin it doesn't want to allow an exception for WSA. Now I'm at a loss, and seeking opinion/advice for possible solution, and wonder if only way is to stop DEP completely with an Elevated Command Prompt? And perhaps that might not be advisable. Thanks for any suggestions.
