If when installing TCS 9 a message appears prompting you to obtain 'Administrator privileges' you can resolve this by doing the following:
1. Find your TCS 9 icon on your machine (most likely on the desktop)
2. Right click on the TCS 9 icon
3. Select the 'Run as administrator' option from the list that appears
TCS 9 will now install completely and allow you to unlock the software as required.
