I am trying to install Extension Manager, but it keeps hanging at 61%. The current try has been stuck at 61% for about the last 45 minutes. When I try cancelling the installation, then the cancellation process seems to freeze instead.
I have restarted my computer, but that didn't solve the problem. I am running Windows 7 Professional.
I need Extension Manager to troubleshoot an InDesign file that just began acting strangely, so I need to get this problem solved. Any suggestions?
