Your computer is missing Windows Installer 3.1 software, which it needs to install Wireless Manager. To fix this problem:

1. Click the OK button on the error message.
2. Go to Microsoft Download Center.
3. Under the Files in this Download section towards the bottom of the page, click the Download button next to WindowsInstaller-KB893803-v2-x86.exe.
4. A pop-up message will appear. Select "Run."
5. After you get a message saying that Windows Installer has successfully installed, run the Wireless Manager installation again.

If the installation finished improperly or some of Wireless Manager’s files become corrupted, the program may crash. If so, it’s a good idea to uninstall and reinstall the program. To enable you to make sure you have an uncorrupted copy of the program, this section will cover reinstallation from the Support Web site at www.sonyericsson.com/support.

NOTE: The following instructions apply only to Sony Ericsson's Wireless Manager. If your modem came with an installation CD with your service provider's logo, please contact your service provider for uninstall/reinstall information.

2. Click Start, then click Control Panel. Double-click Add or Remove Programs.
3. Highlight each of these programs and click Change/Remove:
   1. Sony Ericsson Wireless Manager
