Can't install apk from Package Installer I have downloaded an apk from a site, but now I cannot install it; when I'm trying to install, it just returns me an alert / toast message with: Sorry, no application available
The Package Installer.apk is located in its default location (i.e., /system/app/Package Installer.apk)
I have tried this one time, that I installed Package Installer through Package Installer ...
I have found a solution on the web (from XDA):

Go to Settings &gt; Application Manager &gt; All &gt; Package Installer.
Clear its cache, its data, force it to stop, then reboot.

But, it doesn't work (for me) ...
I have a custom recovery installed: TWRP, and of course, my phone is rooted.  Does this affect the Package Installer?
I had also tried using Third Party &quot;App / Package Installer&quot;, but that doesn't work either (it just lets me pick apks from phone's storage,then install it through Package Installer).
PLEASE HELP!!! ☺
I can't believe it actually worked for me; I just tried it and it worked. Here's the solution:


Move / Copy Package Installer.apk as well as the .odex file of Package Installer from /system/app to /sdcard or whatever folder you may want to copy the file to.
Delete the Package Installer (apk and odex) from /system/app if you've copied it.
Reverse the first step. That would be, copying the copied file and pasting it to /system/app or moving it on to /system/app.
Reboot.
