That solved it! I was having the same issue: Inside product manager, I click "install" on ST4 and it sits there doing nothing saying 'Calculating....' Since I log into Windows as 'Admin', I had to go into preferences inside IK Product Manager & choose a download path that was in /users/admin. Then it worked no problem!
