How Wacom helped me install driver on my Intuos Pro PTH.
I phoned Wacom and got a tech on the phone immediately 🙂
Go to the Legacy Driver link and select the proper table and operating system.
Download 6.3.10
You must use the Wacom Utility to remove all files before installing 6.3.10
If you do not have the Wacom Utility, you need to install 6.3.10 to get the utility and follow these steps through utility:
1. Remove PREFERENCES (select ALL USERS) and wait for the log to say "Done."
2. Remove SOFTWARE.
*** ONLY install 6.3.10 - DO NOT INSTALL 6.3.11.
*** 6.3.12 will be a good release.
