Installation log file location
For most Wacom software products installation log files are created in %TEMP%.
Assuming a Windows login ID of "jsmith" this should equate to: C:\Users\jsmith\AppData\Local\Temp
There is an important exception to this - the Wacom Tablet Driver (as available at https://www.wacom.com/en-us/support/product-support/drivers) creates installation log files in the following directory:
C:\Program Files\Tablet\Wacom
