This article is for those who use Nokia Symbian phones just like me. This post is likely to be useful to anyone out there who is new to Nokia Symbian phones. this is because after buying your Nokia Symbian phone, the first thing that will come to your mind is to install loads of applications on it. However, things are not always that easy especially when you are a novice. So when trying to install Symbian applications, you may have some error messages. By virtue of this, I will use this post to interpret the installation error messages of Symbian.
Interpret the Installation Error Messages of Symbian Phones and Fix the Problem
This post will simply aid you to understand what could be wrong with the file you are trying to install:
Error Message 1
Certificate error. Contact the application supplier.
Hint on how to fix
You may have tried installing unsigned applications. Note that signing is mandatory for S60 3rd Edition. You can use a self-signed certificate or developer certificate from Symbian Signed to sign your application.
Unable to install. Constrained by the certificate.
How to Fix
This message pops up when you attempt to install a developer certificate in the unsupported device. The developer certificate from Symbian Signed can only be used in a limited number of devices. Remember that you have to send your IMEIs to Symbian Signed when requesting a certificate. You cannot use the certificate in other devices that are not in your IMEIs list.
Error Message 3:
Required application access not granted.
Hint About the Solution
Check that your certificate can be used to sign all capabilities needed by your application.
For example, if you use a self-signed certificate, you can only sign basic set capabilities, i.e. network services, ReadUserData, WriteUserData, local services, and user environment.
If your application requires one of the extended capabilities, for example, SwEvent, you cannot sign it with a self-signed certificate. In this case, apply for developer certificates from Symbian Signed.

Error Message 4
Unable to install a protected application from an untrusted supplier.
If you use self-signed certificate, make sure that your application uses unprotected UID, i.e. 0xA0000000 – 0xAFFFFFFF. If you use protected UID (0×20000000 – 0×2FFFFFFF) or legacy UID (0×10000000 – 0×1FFFFFFF), you will get this message.

Unable to install.
This message may come up when your installation file (.sis/.sisx) copies files to other
copies files to other application’s private folder, i.e. privateuid. Note that Symbian 9 introduces data caging concept, it means you don’t have access to other application’s private folder.
Error Message 6:
Set the phone date back by 7-8 months then install the application. After doing that reset the date back to routine.
Application not supported
Maybe you are using a Nokia phone with OS S60V3 and above and you are trying to install an application that is only compatible with Symbian S60V2 and lower… just make sure you get the applications compatible with your phone.
Error Message 8
