I also had problems installing the upgrade...I finally fixed mine by Removing sky anytime through control panel then add/remove programmes.
I then went on sky.com to my own profile,removed anytime from there. I then had to go to Microsoft download center..where i downloaded......NET Framework Version 2.0 Redistributable Package (x86)..
Then went back to sky.com and reinstalled anytime....all is fine now..
Hope that may help others.
