I have a windows 64 bit computer and whenever I download any of the three download options I get the folder in the top picture. When I click Pro Client I get an error, but for last couple of years, before this update, all I had to do was extract it then it would run. However what I get instead is the bottom picture which for some reason removes the pro client. I don't know what to do.

Your antivirus most likely blocked some files from being dowloaded or extracted. Delete all the files, clear your trashbin as well and restart your device. Create an excepetion for PRO on your antivirus software and download + extract it again. Then try to run it again.

How?

There should be something in settings of your antivirus that shows the option.

I'm on the latest windows and I dont see anything

to temporarily disable virus setting on windows to install or updating pro...

go to  start >settings > update & security >  windows security > virus & threat protection  note x2 > manage on virus protection settings > turn real time off  ( it will turn back on itself)  leave open until you have the game installed

 

good luck
