Issues with uninstalling Nitro 13

[harry@wayfairertravel.com 0]

Hi there,

I am trying to uninstall Nitro 13 in order to install Nitro 11 but I am coming across an issue during the uninstallation. I get the following error message and it has been stuck at 15% progress for nearly an hour every time I tried: 

SOMETHING IS BLOCKING NITRO FROM PROCEEDING
No action was taken as system reboot is required.

I have tried to re-start my laptop and uninstall nitro but nothing working so far.

I wanted to send you a screenshot of the error but I don't know how to.

Regards,
