Blackberry Installation Errors

During installation of Blackberry Enterprise Server 5.0.3, I have encountered an error "Error Initializing System". This is a known issue in Blackberry Setup application.

When you run the setup application for the second time and the setup application cannot connect to the Blackberry Configuration Database, the setup application displays the "Error Initializing system" error message and does not permit you to change the Blackberry Configuration Database information.

In order to fix the problem, follow the below steps.

Click Start -> Run
Type Regedit
Perform one of the following actions

If you are running a 32-bit version of windows, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server.

If you are running a 64-bit version of Windows, navigate to 
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Research In Motion\BlackBerry Enterprise Server.

Remove the Database key.
Perform one of the following actions:

If you are running a 32-bit version of Windows, navigate to 
HKEY_CURRENT_USER\SOFTWARE\Research In Motion\BlackBerry Enterprise Server.

If you are running a 64-bit version of Windows, navigate to HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Research In Motion\BlackBerry Enterprise Server.

Remove the Database key.
Restart the setup application.
