I created an inf file that adds a new option to the context menu for .dll files. It allows you to right-click on an assembly and select CAT.Net Scan. This will run the x64 version of CAT.NET against the assembly and generate a report of any security vulnerabilities discovered in the assembly. The report is named the same name as the assembly with a suffix of _report.html.
I have attached the .inf file to this post. You can download it to your computer, right-click on the file and select install. In order for it to work you need to download and extract CAT.NET v1 x64 to the C:\CAT.NET folder. You can download CAT.NET from here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=e0052bba-2d50-4214-b65b-37e5ef44f146
Here is the .inf file I created to install the context menu option: CATNetScan.inf
