The Sumatra PreRelease v3.211105 64bit creates a folder in LocalAppData on my system (W10-64bit),
t.k: c:\Users*user*\AppData\Local\SumatraPDF with in there -> *\extracted\4cf0a5e830f43ff30fd26332a82292a3\unrar64.dll
The stable (v220.127.116.11) release not, which means that the Pre Release is not completely Portable.
(The file unrar64.dll for extracting the Portable possible!)
The question: is that normal for a Pre Release?
Thank you for your time,
I wish you a nice day.
