problem installing SX 3

Cubase
1

hi guys, - I need help in installing SX 3 so I can convert my old .all files to CB 8.
I downloaded SX3.1_CD_Installer_PC from the server but it stops at "skipping file - c\windows\fonts\stein___ttf and I have to kill it via task manager.

I also tried the Update_CubaseSX_3.1.1.944.exe. This stops with the message “there are other activated processes which stop the installations process. Please restart the computer” etc…
The dongle is not attached.
Any thoughts ?
