Unable to activate community version

Hi Team,

I have used UiPath Pro version (2016.2.6274) in my system and today my license got over. So I have uninstalled it.

Now I have downloaded UiPath Community version, but I am unable to activate it and getting the below error.


Please help me to activate Community Version in my System.

You could no longer use community on a machine that was activate previously trough code.
