1) Check your Directx software
In addition to the Logitech installer you will need to check the support software - Microsoft DirectX . This comes pre-loaded on most Windows computers but has to be updated - I am currently on version 11
To start the DirectX Diagnostic Tool, click 'Start', click 'Run', type dxdiag in the Open box, and then click OK
Run through the tabs checking the 'notes' windows for information
The version will be shown on the 'Systems' tab
2) Make sure you have the latest version of Flashplayer installed - use the default browser to visit this site

Download 'ccleaner' and use it daily. Run it through a couple of times,using the factory settings and the 'Analyze' control to see the files offered up for cleaning. Use 'Run Cleaner' to delete these files and then run 'Analyze' again to ensure all files are deleted
Run the 'Registry' from the left hand toolbar but 'Save' any changes after opting to 'repair' errors.Never make changes to your Registry without saving the information.
