Troubleshooting - Drivers and other system software
In order to maximise performance and reduce the likelihood of errors we recommend keeping your graphics card drivers, DirectX, .Net 4.0 and C++ up to date.
You can download the most recent versions of each below:
Graphics Card Drivers
If you do not know what type of graphics card your PC has then the easiest way to find out, in all versions of Windows, is to run "DXDiag" and go to the display tab. In Windows XP you need to go to Start>Run>DXDiag, whilst in Vista, 7 and 8 you simply need to type in DXDiag and hit enter after you click the start button.
The drivers themselves can also be manufacturer-specific, and as such you may need to contact your PC manufacturer for up-to-date drivers if you have a laptop or pre-built PC (Such as a Dell).
Windows Software
Some users have resolved startup issues by installing .NET 3.5 as well as 4.0 - you can find the installer here:

On some XP Machines you are required to install the Windows Imaging Component prior to installing .NET 4.0 - you can get it here:

On XP Machines some users have been required to install C++ 2008 service pack one to allow Muvizu to run:
