How to determine which versions of the .NET Framework are installed

Thursday, April 29th, 2010

To determine which versions of the .NET Framework are installed, locate the %systemroot%\Microsoft.NET\Framework folder. To open this folder, you can paste this address into a Windows Explorer address bar. The following folders contain the released versions of the .NET Framework:

  • v3.5

  • v3.0

  • v2.0.50727

  • v1.1.4322

  • v1.0.3705

Note If you see other folders that have a vN.N.NXXXX format, they may contain beta versions or pre-released versions of the .NET Framework. Those versions are outside the scope of this article.

To determine which versions of the .NET Framework are installed on a computer, follow these steps:

  1. Open any one of the folders in the previous list.

  2. Right-click the Mscorlib.dll file, and then click Properties.

  3. Click the Version tab, and then note the file version.

  4. Use the previous list to determine which version of the .NET Framework is installed on the computer, and then click OK.

My coworker Leigh had an issue installing .NET 3.5 SP1 It would start the installation however never complete and with no errors in event logs. After some research it appears the workaround is to install latest Windows Installer (currently 4.5)

After installing and then running the .NET 3.5 SP1 installer it sucessfully completed.
