Otherwise, if you have a PAC Mate running version 4.1 or earlier, download the file PMViewer.exe. Your computer must have Windows XP or earlier in order to use this version of PMViewer.

How Do I Install It?

The following steps describe how to download, install, and use PMViewer.

Downloading PMViewer1.3-32bit-64bit.msi

Note: This version of PMViewer will only work with PAC Mate Omni. Do not install this software if you are running PAC Mate 4.1 or earlier.


If you have previously used, or attempted to use, the orriginal PMViewer application with your PAC Mate Omni, do the following before installing this new version:

  1. Open File Explorer on your PAC Mate Omni and navigate to the Windows\StartUp\Programs folder.
  2. Locate the Cerdisp application and delete it. If you are unable to locate this file, proceed with the installation of PMViewer 1.3.


  1. Save the PMViewer1.3-32bit-64bit.msi file to a folder on your computer that you can easily remember. You might choose to save it on the desktop where you can quickly find it.
  2. If necessary, use Windows Explorer to locate the file and press ENTER.
  3. The application is automatically installed on your computer and a PAC Mate Viewer 1.3 shortcut is placed on your desktop.

Downloading PMViewer.exe

Note: This version of PMViewer is not compatible with Windows Vista or Windows 7. Do not use it on these operating systems.


  1. Save the PMViewer.exe file to a folder on your computer that you can easily remember. You might choose to save it on the desktop where you can quickly find it.
  2. If necessary, use Windows Explorer to locate the file and press ENTER.
  3. Unzip the file's contents to C:\PMViewer. A folder titled PMViewer is created. It contains files that you will use to install and run the application.

Installing Remote Display Control and PMViewer

Note: When installing the software, you must establish an ActiveSync connection between your computer and PAC Mate.


  1. Connect your PAC Mate to your computer and establish a standard or guest partnership using ActiveSync.
  2. Use Windows Explorer to navigate to the C:\PMViewer folder, select RemoteDSP.exe, and press ENTER. ActiveSync will then ask if you want to install it on your PAC Mate. Follow the prompts.
  3. While still in the PMViewer folder, locate the PMViewerInstall.exe file and press ENTER. This starts a Remote Display Control session between your computer and PAC Mate, and it creates a PMViewer shortcut on your desktop.
