Start Recording button disabled in HP LoadRunner Vugen 11.50

I was trying to record a web application using Web/Http protocol, but somehow I couldn't begin recording because the "Start Recording" button is disabled.

Current setup:
HP LoadRunner Vugen 11.50
Internet Explorer 11 Cause:
Internet Explorer 11 is not supported by Vugen 11.50

Possible solutions:

  1.  Downgrade to Internet Explorer 10 or
  2. Upgrade to LoadRunner Vugen 12.00 or
  3. Install LoadRunner 11.52 service pack - this worked for me! I can't simply upgrade to Vugen 12 because it's team standard, and IE11 is the company standard browser hehe. In short I can't touch those two. Helpful links here and here.
