raymo,
I have found this
http://canon-utilities-zoombrowser-ex.updatestar.com/ , it looks ok, and have now found this
http://www.microsoft.com/en-in/windo...=Windows%208.1 have a read of it, I would be tempted to try it, create a restore point first in case things go horribly wrong (I dont think it will).
The person on that site is having problems as they installed the program and then upgraded their operating system, as you are not upgrading the operating system, just the software, it may well be ok.
What is your "old version", maybe that can be run in compatability mode.
Interested to know how you go with it.
Cheers
Andrew
