Hi Sean,

Are you using any third party securuty software?


If yes, I would suggest you to disble the third party security program and check if it helps.


Follow the steps given below.


Disable third-party Security Software

 

a)      On your Computer screen Task Bar next to System Clock.

b)      You will see the third-party Security Software Icon.

c)      Click on the third-party Security Software Icon, you will see a pop up.

d)      In that pop and select the option to disable, click on it.

 

Now the third-party Security Software will be disabled.

 

Important Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
