Microsoft Visual J# 2.0 Redistributable Package

What is Microsoft Visual J# Redistributable Package?  (from Microsoft)

The Visual J# Redistributable Package is not intended to run applications written with other Java-language development tools. Applications and services built with Visual J# will run only on the .NET Framework and will not run on any Java Virtual Machine.


Microsoft Visual J# 2.0 Redistributable Package is a program developed by Microsoft. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The program adds a toolbar to Microsoft Internet Explorer. The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The software installer includes 113 files and is usually about 77.89 MB (81,678,783 bytes). In comparison to the total number of users, most PCs are running the OS Windows 7 (SP1) as well as Windows 8. While about 32% of users of Microsoft Visual J# Redistributable Package come from the United States, it is also popular in Germany and Iran.
