Running Cubase sx

I want do drag a couple of old tracks up that were done on Cubase sx.
I have the old CD installer (32 bit) but when I try and run it it says something along the lines of - some other process is interfering with the installation please restart your computer.
I did this with no joy.
The only SX version I can see on the Steinberg download pages are sx updates and not the full installer.
My PC is Win 10 64 bit
Anyone got any ideas?

You can download the full installer here:

Any idea how to open .all files?

Thanks mate
