Hi JagjitSingh ,
Please refer to document : https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed
On the Start menu, choose Run.
In the Open box, enter regedit.exe.
You must have administrative credentials to run regedit.exe.
In the Registry Editor, open the following subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP
The installed versions are listed under the NDP subkey. The version number is stored in the Version entry. For the .NET Framework 4 the Versionentry is under the Client or Full subkey
(under NDP), or under both subkeys.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full
Note that the path to the Full subkey includes the subkey Net Framework rather than .NET Framework.
If the Full subkey is not present, then you do not have the .NET Framework 4.5 or later installed.
Check for a DWORD value named Release. The existence of the Release DWORD indicates that the .NET Framework 4.5 or newer has been installed on that computer.
The value of the Release DWORD indicates which version of the .NET Framework is installed.
<div class="IMPORTANT alert">
The following table lists the keys of released versions of the .NET Framework only. It doesn't list the keys of preview or pre-release versions.
