I purchased it on DLsite, but found it's encrypted and can only be opened using CypherGuard PDF and Adobe Acrobat Reader DC. for some reason i was unable to try the 7-day free trial of Acrobat, so I didn't even have the opportunity to try using the export function Is there any way to extract the images from it?
no, i don't need a PDF tool. i mean the dlstie version only could be read on website or the two i mention. And i'm not going to purchased it again on booth, sorry.
