I went to the official Microsoft site to install URLScan 3.1 from here
Web Platform Installer 4.6 is unable to find the extension to
IIS. I've looked in the complete list, as well as under the server product list (which should be a subset).
My O/S is
Windows Server 2008 R2 Enterprise and I'm using
IIS 7.5, which appear to be supported.
Any idea why the Web Platform Installer can't find the product? I couldn't find any information suggesting that the product is deprecated.
EDIT: I was able to download it directly from here. However, as pointed out by MichelZ, I'm not sure if it is now obsolete.
