everytime I try to remove app that I download by myself. show this error and close the app.
"the application package installer (process com.android.packageinstaller) has stopped unexpectedly."

when I go to menu>> setting >> Applications >> Manage applications
try to "uninstall" a game HomerunBattle3D. It will show Sorry! Box "the application package installer (process com.android.packageinstaller) has stopped unexpectedly. Please try again. " and Force close buttom only. and Click the buttom nothing happen.

I can from market uninstall some app. but only some of them I download myself can not be uninstall.

Need a lot more information.

Rooted not rooted? What Rom ? What apps? And everything else ...

Are you rooted? If so, download Titanium back-up. Open the app, and click the "Problems?" button so it installs Busybox. Once done, click backup/restore at the top of the screen, find the app in the list and uninstall it using this app.

If ur rooted then download titanium backup*root, use it to uninstall any you want,

in case ur not rooted, try app uninstaller from market, and if they fail to work, root your device using z4root and then use the titanium backup app.

Give it back to whoever rooted it for you and ask them what to do.
