You successfully complete the automatic installation process, but Watcher does not detect the AirCard USB Modem:

1.Click Start, and then click Control Panel.

2.Double-click TRU-Install.

3.When you are prompted to switch to modem mode, click OK.

4.Wait for Watcher to detect the AirCard USB Modem.

5.If the AirCard USB Modem still is not detected, connect to the Internet using another method and go to www.sierrawireless.com/support for assistance.

When you try to install or uninstall Watcher, the message Windows Installer is not accessible (Error code: 1601) appears.

To fix Error 1601, first see if another installation process is running.

3.Check the running processes for any of these names:

·setup.exe

·isetup.exe

·ikernel.exe

·msiexec.exe

·idriver.exe

·IsUninst.exe

·Uninst.exe

If any of these processes are running on the system:

1.Select each process.

2.Click End Process.

3.Try to run the Watcher installation again.

If the installation is not successful, connect to the Internet using another method and check Sierra Wireless Knowledge Base articles at sierrawireless.com.
