Answering both responses:
My W7 installation is plain ol' English.
When Creator 2011 Setup starts, the first window, titled "Setup" states "Select your preferred installation language. It then gives a series of choices. "English" is the second choice and is pre-selected.
When I hit "OK" I get an "Error" window (don't have a screen capture utility on the laptop - sorry) that states:
This operating system does not meet the minimum requirements for Roxio Creator 2011 Special Edition.
This product will not be installed.
Microsoft Windows XP SP2 (64-bit)
Microsoft Windows XP SP 3 (32 bit)
Microsoft Vista SP2 (32\64 bit)
Microsoft Windows 7 Home Premium, Professional, or Ultimate (32\64 bit)
There is no other information provided in the Error window. From my Control Panel System Info:
Windows 7 Home Premium, 64 bit.
I'll open the Capture USB issue in a new thread.
