Free DotNet VersionCheck Utility

If you've ever wanted a quick way to find out which versions and service packs of the .NET runtime are installed on a machine, or if you're trying to resolve a 'missing mscoree.dll' error, then DotNET Version Checker is for you. (Note: if you're interested in the version of the Compact Framework on a Pocket PC see the notes at the foot of this page).

VersionCheck itself does not depend on the .NET runtime.

VersionCheck will also tell you whether you have the required Windows components to run .NET applications, and will prompt you with download locations if not.

You can download a free copy of DotNET VersionCheck.exe here.

VersionCheck lists all the installed versions of the .NET runtime on your machine and can currently identify the following versions of the .NET runtime: (Note that not all of these are public releases, but you may encounter them on development machines etc.)

VersionCheck also checks that you have compatible versions of the ADO Database runtime and Internet Explorer installed.

How Does VersionCheck Work?
We check for the presence of .NET runtimes and service packs using the method described by Microsoft here, though we have found that doesn't work in some cases so we get the version number from the Mscorlib.dll.
Internet Explorer and ADO versions are checked by looking up the progid of a known COM server and reading the version information of the file referenced by the corresponding InprocServer32 registry key.
For Version 3.0 of the runtime (which is actually a set of libraries that utilise the 2.0 runtime) we currently check the version of the Windows Communication Foundation\System.ServiceModel.dll

Checking the version of the .NET Compact Framework on a Windows CE / Pocket PC device:

In order to see what version is installed, use File Explorer to navigate to the \Windows directory on the device, and click the file called CGACUTIL. You will get a message box showing you the Win32 File Version of the .NET Compact Framework installed on the device.

These are the versions we've found up to version 2.0. The cgautil.exe method above still works for more recent frameworks, but we haven't been following the version numbers. If you know any, please let us know...:

• 1.0 RTM = 1.0.2268.0
• 1.0 SP1 = 1.0.3111.0
• 1.0 SP2 Recall = 1.0.3226.0
• 1.0 SP2 Beta = 1.0.3227.0
