How to tell which .NET Framework SP is installed

Here's an easy way to tell which .NET Framework 2.0 service pack is installed. Open a command line and enter the following command as a single line:

reg query "HKLM\software\Microsoft\NET Framework Setup\NDP\v2.0.50727" /v SP

For .NET Framework 3.0, enter:

reg query "HKLM\software\Microsoft\NET Framework Setup\NDP\v3.0" /v SP

The commands will return the REG_DWORD value for the SP version (0x0 for RTM or 0x1 for SP1).

Various .NET Framework updates and releases are available for download:

• .NET Framework 3.5 (available as a web install or a downloadable full package)
• .NET Framework 3.0 SP1
• .NET Framework 2.0 SP1 (available as x86, x64 and IA64 packages)
