The system administrator has set policies to prevent this installation

Another dumb error message.

While installing ActiveWriter, it asked me to install DslToolsRedist. Trying to do so raised the said error message. I was on my way to shot the admin, but then googled a bit, and found out on http://www.appdeploy.com/messageboards/tm.asp?m=8872&mpage=1that it is caused by prior installations of he same product that was not fully removed from the registry while uninstalled. Searching “DSL” in HKEY_CLASSES_ROOT\Installer\Products\ showed me that a previous CTP left some dirt in my registry. Removed that key, reinstalled DslToolsand the ActiveWriter magic could finally started.
