Generally, OCB configures itself at the first
start. But if you installed OCB and WinRAR to different drives or
you haven't installed WinRAR before installing OCB, you will be
asked to specify WinRAR.exe path manually. In order to do it, click
"Options" menu to go to the Settings window, General tab and
find WinRAR.exe using "Find WinRAR.exe" button (or enter full path
manually - usually it is "c:\program files\winrar\winrar.exe").
Temporary folder is also set automatically to the
default Windows temp folder, but you should check that this disk
has enough free space to create large archives.
The other settings are already set to default
values which normally satisfy most users, so you can get back here
any time later to customize OCB for your needs.
