That is a disappointment
I'd like you to take one more shot at this before you ask for your refund. Note: I am just a fellow user like yourself. If you don't want to do this, it won't have any effect on your refund status!
Up top under Support is Software Updates. For the Roxio GameCAP there is an SP2 update you can download. It is the Full Install! Download it per the instructions but do this first before trying to install it!
Unplug your RGC Device and put it aside until you are completely finished.
Download and install the Revo Uninstaller. Then run it inModerate Mode to remove any traces of Roxio.
Create a New User Account with Administrator Privileges.
Turn OFF any A/V & Firewall.
Reboot and log on to that new account.
Use the SP2 download and right click on Setup.exe and select Properties.
Under the Compatibility tab, make sure nothing is checked!
Right click Setup.exe and select Open.
Don't do any updates at this time (get it running first)
Use the Default Locations!
When the Install competes, turn your AV & Firewall back on and reboot.
This is the limit of my good guess's, I hope it works!
