Not able to install .apk build from apktool

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Downloaded Angry Bird Rio.apk from internet 
2. Used debug command to decompress the above .apk (I used command apktool.bat  
d "Angry Birds Rio.apk"). Folder names "Angry Birds Rio" got created that had 
decompressed files as expected.
3. Just did a build of  "Angry Birds Rio" folder again (apktool.bat b "Angry 
Birds Rio" "Angry Birds Rio.apk"). As expected I can see "Angry Birds Rio.apk" 
got created. 
4. Tried to install this new *.apk on my Samsung Galaxy Ace device and could 
not be installed? I just get an error "Application not installed"

What is the expected output? What do you see instead?
Application should have installed successfully.

What version of the product are you using? On what operating system?
Product version --> 1.4.1
OS --> Windows Vista

Please provide any additional information below.
I have also tried to do similar steps on .apk originally build by me but I am 
having same problem with it also. 
Please let me know if in case any help/more information is required on this.

Did you sign this apk before install?

No. I did not. I am a such a new user to Android that I did not know about 
this. Just read on how to sign the application and came  to know it is 
basically mandatory. 

Just one more question, Will I be able to sign the Third party app? As in my 
case I downloaded, debug and build the third party app.

Thanks for your help.

Yes, you can sign any apk you want. But you will have to uninstall original app 
first and then install modded one. You can't update it directly, because both 
apk files are signed using different keys.

here is a link on how to sign the APK:
http://developer.android.com/guide/publishing/app-signing.html

I think it also explains on how to sign APK for eclipse users.

Other then this I do not have a practical experience of signing APK.

Brut,
I really appreciate and thanks for your help. You can now close this ticket 
please.
