(Information about Proxifier for Mac is available in a separate document).
There are two different editions of Proxifier for Windows:
The main goal of the Portable Edition is to help people who have no opportunity to install the software on a computer or deal with multiple computers and would like to save time on installation. The Portable Edition requires no installation and can be run from a USB stick. You can work from an Internet cafe or on a computer with guest access only.
Standard Edition is more suitable for users who have their own PCs at home, at work, or in a corporate environment.
A comparison chart of the main features is listed below.
