I have searched for the Instagram private profile viewer zip password and find that there is a file which can be downloaded which claims to contain it.
However, to be honest, I wouldn't trust the site that it is on for the following reasons:
1. There is no way to really tell what the file contains without opening it and when you do you open your pc to the possibility of malware etc and to me that is just too big a risk, especially given the name of the site which suggests it is not the safest one out there.
2. After a little digging around, I found that the private profile viewers are said to be scams which just collect information/passwords from you in order to hack your account
To me that is just too big a risk but obviously the ball is in your court.
