Sybase Unwired Platform Installation Prerequisites

Configure your environment before launching the Sybase Unwired Platform installer.

Delete the JAVA_TOOL_OPTIONS environment variable

If you set the JAVA_TOOL_OPTIONS environment variable, delete it before installing or uninstalling Sybase Unwired Platform.

Right-click My Computer and select Properties.
Select the Advanced tab, then click Environment Variables.
Select JAVA_TOOL_OPTIONS, then Delete.
Click OK to exit the Environment Variables dialog, and OK again to exit the Properties dialog.

You can also delete (set to NULL) the environment variable through the command window.

set JAVA_TOOL_OPTIONS=

Note: As an alternative to deleting the environment variable, you can unset it from a command prompt window before running the installer from the command prompt window. If you are uninstalling Sybase Unwired Platform, launch the uninstaller using Add or Remove Programs in the Control Panel.

Turn off User Account Control (UAC)

Windows Vista and Windows Server 2008 incorporate a new security model, UAC, which limits user access to application software until an administrator grants increased privileges. UAC interferes with the Sybase Unwired Platform installer.

Before launching the installer, turn off UAC to avoid installation errors.
