Microsoft .NET Framework
If you're going to install and use the latest ATI Catalyst Control Center, which is part of the normal ATI Catalyst Software Suite, you
must first install the
Microsoft .NET Framework (Version 2.0) on Windows XP - Vista already comes with .NET 3.0. Download the .NET package and install it, and then make sure to visit the Windows Update site and check for any additional updates for .NET regularly. The .NET package is absolutely necessary if you want the ATI Control Center to work.
If you're wondering what the .NET Framework is, and why it needs to be installed for the ATI Control Center to work, basically ATI has decided to use the .NET Framework as the platform for developing the Catalyst Control Center functionality. .NET is not required by the graphics drivers themselves, it is required for the Control Center. .NET allows developers to easily program in more functionality in the driver's user interface, especially for Windows Vista. Of course there are downsides to this for users, such as an incredibly bloated startup process and background memory usage. If you have installed the .NET Framework primarily to use the new ATI Control Center, you can disable two .NET aspects to reduce your startup time, reduce resource usage and still have no impact on the functionality of your system or the ATI Control Center:
1. Go to Start>Run and type "Services.msc" (without quotes). In the Services dialog box, if you find the '.NET Runtime Optimization Service' then set it to Disabled. If you find the service 'Windows User Mode Driver Framework', set it to Disabled, however note that some media players like Windows Media Player require this service to remain enabled if you want to synchronize with a hardware media player.
2. Go to Control Panel>User Accounts and select the 'aspnet_wp ASP.NET Machine Account' (or similar), then choose to Delete it. This account is only necessary if you do software development work using the .NET Framework. Alternatively you can delete this account by going to Control Panel>Administrative Tools>Computer Management>Local Users & Groups>Users and disabling the ASPNET account. Should you ever need to recreate this account, go to your .NET folder (usually
\WINDOWS\Microsoft.NET\Framework\[versionnumber]\) and run the
aspnet_regiis.exe file.
