Installation problem in SX3

I tried installing SX3 on a Wondows XP computer and got this message:

“There are other activated processes which disturb the activation process. Please restart the computer and start the installation”

No other program is running.

The CD is fine because I just used it on my older computer, but the motherboard was dying so I’m switching over to this new one.

Any ideas?

I worked it out. It was the eLicenser. I uninstalled its software, installed SX3, and everything was fine.
