Strange Plugin Issue-Cubase 5- 32bit files

I am using vers. 5.1.1. I dl’d updates and clicked to execute files, after 15 secs. nothing happened? I tried both updates? same 15 secs… asked If I wanted groove plugins and then nothing? Vers. is still 5.1.1
I don’t want to go newer than vers. 6 because of bloat in software with vsti’s.
any ideas?
