"Unable to install" on some s60 handsets

[parsa28]

Hello there,
I've done a J2ME MIDlet and it works fine on my E65. But I tried sending it to a friend to try it on her N81 8Gb and she says she gets "Unable to install" after Preparing to install step.
I've hacked my E65 long ago so it can install unsigned MIDlets.

E65 is: v9.1 , S60v3 (initial release), MIDP 2.0, CLDC 1.1
N81 8Gb is: v9.2, S60v3 FP1, MIDP 2.0, CLD 1.1

and the rest specs are the same.

I wonder what causes this ? is it the signing or the OS version ?
Thanks for your time.

If the MIDlet is signed MIDlet, what certificate are you using for signing?
(remove the signing information and try to install... does it work?)

Hi Hartti,
No i haven't done anything about signing this application.
Btw, by googling I found some similar cases about themes, midlets and other stuff and there were some odd solutions like removing memory card while installing or using data transfer mode instead of Nokia PC Suite installer and all.
p.s.: and her App. Manager settings are as mine: Software installation => All, Online certif. check => Off

I'm so worried about this cuz she's able to install my other MIDlets.
Any ideas ?

What are the contents of the JAD file and what APIs are you using the in MIDlet?

Hi Hartti,
The jad file is:

MIDlet-Name: MyApp
MIDlet-Version: 1.0.1
MIDlet-Vendor: MyName
MIDlet-Jar-URL: MyApp.jar
MIDlet-Jar-Size: 171885
MIDlet-Description: MyApp
MIDlet-Icon: /myapp.png
MIDlet-Info-URL: http://www.mydomain.com
MIDlet-1: MyApp,/myapp.png,myclass

All the info matches the manifest file.
But I found that when I bluetooth the file everything's fine ...I had sent the file over Yahoo messenger when the error occured.
I'm actually going to put it on my own website for public download so what might be causing the problem ?

Hey there,
Unfortunately the problem still exists. i'm going crazy!
When sending the MIDlet via bluetooth everything's fine.
But when downloading it from the web, it says "Unable to install"(On N81 8GB) or "Invalid jar file"(On E65) or "Invalid application" (On 6300)
Please, someone , any clue ?

Do you have the right MIME-type definitions on your server for JAR and JAR files?
Can you also check from the manifest file inside JAR file and find out the value of these attributes
# MicroEdition-Profile
# MicroEdition-Configuration

Those should be 2.0 and 1.1 respectively
