NetFrameworkChecker

About this project

This program reads the version of .net framework installed on your computer and compares it to a required version.

If you don't have the required version, the program displays 2 versions of the requied .net installer (one offline and one online).

You also can click on the install button which will download the online installer and start it.

This program required at least .net 2.0 to run; but betting that your end user has 2.0 installed is a pretty safe bet.

Start / options

NetFrameworkChecker.exe "required_version" "software_name" [-ShowOnlyIfNotInstalled]

• required_version : the .net version actually required
• software_name : name of the software that needs .net, to inform the user why he has to install .net framework
• [-ShowOnlyIfNotInstalled] : optional, to specify that the program must not be shown if the required version is already installed (silent checking)

Example :

NetFrameworkChecker.exe "4.6.1" "3P" -ShowOnlyIfNotInstalled
