I have been using NOF XII. I uninstalled it and tried to install the NOF 2013. The installation proceeds to the end and then fails with the message "Unable to create shell objects". The program then uninstalls.

I am using Windows 7 Home Premium, i7-2600, 16GB DRAM, plenty of storage space.

I have AV, I turned it off,
I ran as administrator.

Is there anything else I need to do?
