Winrar Pro 3.90

The difference from other versions posted here is,
that you do not need zip or other archiver software installed
to extract this great archiver software.
It is self extracted and can be installed on any new operating system,
which has no archiver pre-installed.
All you need is to extract the file to your hard-drive,
then start the installer exe file.
NO further patching or registering is needed.
