Hi,

From where are you downloading Java? Try the official Java site if you haven't already:

java.com: Java + You

Are you downloading (and trying to run) the offline or online setup file? (If you just click the big red 'Download' button, it'll send you the offline installer which downloads more components after you launch it to install them.)

The "unknown publisher" warning isn't really so unusual. You should be able to just allow the installer to run anyway. Is that what you're not able to do?

I thought you were getting the "unknown publisher" message at the start of the installation, not near the end. Could you give us the exact, full text of that error?

Have you actually tried downloading the offline installer yet?

I found it finally mercy!

I read that page a lot of times but I COULDN"T FIND THE PROBLEM(exactly the same problem as you).But I
thought...hmm.Unknown publisher... but if I download that file (only that from a site?).I did that and.. IT FINALLY WORKS I HAD TRIED TO INSTALL IT SO MANY TIMES.So ,if you have this problem untill today,and you want to solve it after 4 years just download the file from that link (https://sourceforge.net/projects/javaclientmsiinstallers/) un-zip the file and install jre1.8.0_77.
Άρε Έλληνα, ένα minecraft ήθελα να παίξω κι εγώ και το java με έπρηζε! Το πρόβλημα όμως λύθηκε. Δεν ξέρω αλλά εγώ πήγαινα να κατεβάσω και το δεύτερο αρχείο που μου έβγαζε μετά (δεν ξέρω αν εσένα στο έβγαζε) αλλά μόλις έκανα εγκατάσταση το jre1.8.0_77 έφτιαξε.Ελπίζω να μην άργησα και να μην το έχεις φτιάξει/ξεχάσει ή να δεν σε νοιάζει.
