Not able to startup the LoadUI on my windows7 box

I downloaded the latest release today and installed on my box. But unfortunately It gives following error:
"Failed to validate certificate. The application will not be executed."

Following details get displayed while I click on Details:

I did not restarted my PC so is this cause issue?

Also, please find attached keystroke.jks file.

Let me know any more information is required.
