.NET issue on app launch: Unable to find a version of the runtime to run this application

When I try to launch cyberduck the above message appears. When I click OK the message goes away and the application does not launch.

I am running windows 7 64 bit, and have the latest .NET 4.0 updates from windows update. I did some googling and maybe the issue is that you have targeted cyberduck at another .NET version? Perhaps a solution can be found here .NET issue on app launch:

Try installing the .NET framework manually from either

I installed the 64 bit net client profile linked above, after which Cyberduck ran successfully. Windows update then prompted to install "Security Update for .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2160841)"

This installed succesfully, restarted my machine, and Cyberduck continued to work properly.

Guess there was some sort of damage to my .NET 4.0 install? Not sure what other .Net 4.0 programs I'm using, but I hadn't seen that error message elsewhere.

At any rate, resolved, thanks!
