I just got a certified like new android and I'm trying to manually download and reinstall all my old apps. Two of them - Angry Birds Lite and full version of Labyrinth, will download just fine, but I get an "Installation unsuccessful" message when it tries to install. I've tried several times. I am not rooted. I went onto my SD card and removed the .com files (I don't remember the full name of the file) but it still won't let me install. Anyone know what could be wrong?
Edit: Fixed it by removing the SD card to install it. Guess something there was still conflicting with it. Thanks.

Yeah that was where I originally started. Everytime I try to download from there when it gets to 100% it says Unknown Error - 18 and then it disappears....
Someone said try getjar and once I clicked on install it says right away installation unsuccessful. Not sure what's wrong....

Lately when I get Installation Unsuccessful it's because the app is on the SD card. I manually move the app back to the phone, let it update and then manually move it back to the card. It's a pain.
But I've also noticed than not all apps on the card have a problem updating. Some work just fine.

I've been getting this lately too.
I am rooted, and after flashing a new ROM, I went to get all my apps back. The only 2 that I want back and can't get are Angry Birds and Blogaway. I get the Unknown Error -18 every time. I've wiped the data on the whole damn phone and I still get this error, and can not download them to save my life! I can't figure it out.OG Droid > Moto Droid 3.

Re: Installation unsuccessful?
After doing some research I figured out how to get around the problem.
If you are getting an "Update Unsuccessful" message...
Some apps like "Android System Info" and "Apps2SD" have a feature that let you move apps to the SD card. Sometimes a portion of an App would actually remain on the phone causing the update error. Move the app off the SD card and back onto the phone and try updating again.
If you are getting an "Install Unsuccessful" message...
I'm not sure what causes this error. However if you go into your "settings/SD card & phone storage" and unmount the SD card you should be able to download and install the app that's giving you trouble. After your done mount your SD card. You may want to also restart your phone.

Re: Installation unsuccessful?
I don't know where to write this (what and where are tags, posts, threads, replies. I've never been in a forum before). I was just wanting to download google earth, but "item cant be found". It's not important enough to tear my new phone apart or anything (not no techie). Just wondering if anybody else has the same prob. Can't find help from google.
