From version 3.0
"replaced non-free UnRAR with a free RAR extraction library. If some CBR files fail to open for you, download unrar.dll from http://www.rarlab.com/rar_add.htm and place it alongside SumatraPDF.exe"
The portable apps doesn't have the option to install unrar.dll from rarlabs.com.
Any chance?
Sorry for my english
Thanks
It's a manual process. It works the same way with our package. You just place it within SumatraPDFPortable\App\SumatraPDF.
Sometimes, the impossible can become possible, if you're awesome!
