Root I Cant Install Application Manager on BOE ROM

[Unit]

[Broken Out Esteem] ROM
I cannot install the application manager & I'm not really sure why, When I Try it will say "Application Not Installed" And even when i only use the back button on the MetroWEB app, It never completely exits, So Its always running in the background along with some other apps that wont completely close, Please help me out?

& I feel Using Task Killers use alot more battery than The Application Manager itself, If I have no other choice then ill just use a task killer.

But can anybody help me out on this problem?

Thanks In Advance!

I think that's a system app.
Try this!

Place APK file in the root folder on your sd card.

Download terminal emulator.

Open terminal and enter these commands:

# su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cat /sdcard/filename.apk > /system/app/filename.apk
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
# reboot
