Original: Get machine installed. NET version in several ways

When investigating application problems, it is often necessary to first confirm the version of the. NET Framework installed on the target machine. The version number can be confirmed in the following way:

• Querying through the Control Panel installer
• Get version information by querying the registry
• Get version information by viewing the installation directory
• Get version information by using WMI commands

Querying through the Control Panel installer

Get version information by querying the registry

To find the key in registry regedit:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\ndp\v4\full

The following results are obtained:

The corresponding results are as follows:

Value of the Release	Version
378389	. NET Framework 4.5
378675	. NET Framework 4.5.1 installed with Windows 8.1
378758	. NET Framework 4.5.1 installed on Windows 8, Windows 7 SP1
379893	. NET Framework 4.5.2

%windir%\Microsoft.NET\Framework

And the corresponding results are usually:

C:\Windows\Microsoft.NET\Framework

However, this lists only the directories, it is not possible to determine whether. NET 4.5 or. NET 4.5.1 are installed, and you need to view the DLL version details directly.

• 4.0.30319.18052 =. NET 4.5 on Windows 7 SP1 64-bit
• 4.0.30319.18408 =. NET 4.5.1 on Windows 7 SP1 64-bit
• 4.0.30319.34209 =. NET 4.5.2 on Windows 7 PS1 64-bit
• 4.0.30319.34014 =. NET 4.5.1 on Windows 8.1 64-bit
• 4.0.30319.34209 =. NET 4.5.2 on Windows 8.1 64-bit
