Why the Fuck Won’t My SIS File Install
Just ran across the online SIS file debugger whythefuckwontmysisfileinstall.com. Pure genius! I think that’s exactly the phrase I’ve used about a dozen times in the past trying to figure out what exactly might have gone wrong with an application install that throws just a generic error. The E61 has actually been pretty good in this respect, I have it set to allow any installs. Not all devices are that nice however.

You need to go to app manager and options- settings- authentication- set it to NO. This should fix it.
