Certificate Error on installing PythonForS60

Question

I am trying to create a small application for Symbian mobile phones using Python. Being a beginner i am having some trouble in setting up the environment for development. I installed Symbian3 SDK,PyS60 Application Manager ( for creating the .sis files to be installed on phones) and python 2.5.2 . I created a small hello world program and created its equivalent .sis file. But when i try to install it in Symbian 3 SDK, it gives me a 'Python Run time Error' ; i suppose it is because there isnt any python installed on the SDK. But when i tried to install the PythonForS60.sis file, it gives me a certificate error. I tried downloading the file through SDK, again it gives me a certificate error. I tried certifying the application through SymbianSigned.com, then it gives this error "The .sis file contains capabilities that are not permitted for Open Signed (Online) FAILURE: Submitted .sis file uses a UID that is not allocated to the account holder matching this email address (0x20022ee8 ) FAILURE: Submitted .sis file uses a UID that is in protected range and is not allocated to the account holder matching this email address (0x20022ee8)" . Can somebody help me to solve this..??

Answer 1

Open Application Manager on your Symbian phone, go to settings and select Software installation. Change it from Signed to All. This will allow you to install applications which don't have a certificate, such as the SIS file you just packaged.

Also note that PythonForS60 2.0 works only with Python 2.5.
