Installation failed

I’m trying to install inSSider, but it keeps failing.
I get a pop up saying “Installation Failed” along with a setup log. Log is:

HI crashdavis6613,

Sorry to hear about the trouble!

Can you try repairing your .NET framework:

.NET Framework Repair Tool

If that doesn’t help, can you try downloading inSSIDer here using a different web browser and send over a screenshot of the error?
