How to Run VCOM as Windows Service

VCOM is a Windows Application. It is NOT a Windows Service. VCOM will auto-run when user has logged into (entering user name and password) Windows. Otherwise, VCOM will not run.

To run VCOM as a Windows Service you can manually create a Windows Service using these steps. However, take note that you cannot run VCOM as both Windows ApplicationĀ and Windows Service mode at the same time.



  1. First, IP address of MobiGATE and all 8 modems must be properly configured in VCOM application.
  2. Disable “auto-start” in VCOM application:
  3. Exit completely VCOM application.
  4. Download and install Windows Server 2003 Resource Kit Tools from Microsoft web page or from here …
  5. Only 2 executable files are needed:
    1. INSTSRV.exe
    2. SRVANY.exe
  6. After you have installed, run this command in command prompt:
    C:\Program Files\Windows Resource Kits\Tools>INSTSRV.exe VCOM "C:\Program Files\Windows Resource Kits\Tools\SRVANY.exe"
  7. Run Registry Editor (Regedt32.exe), check the registry to verify that the ImagePath value under “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VCOM” is set to
    "C:\Program Files\Windows Resource Kits\Tools\srvany.exe"
  8. Right click on VCOM, from the Edit menu, click “Add Key”. Type the following and click “OK”:
    Key Name: Parameters
    Class : <leave blank>
  9. Select the “Parameters” key, click “Add Value”. Type the following and click “OK”:
    Value Name: Application
    Data Type : REG_SZ
    String : C:\Program Files\VCOM\VCOM\vcom.exe
  10. Exit Registry Editor and goto “Computer Management > Services” configure “VCOM” to run “Automatic”
  11. After service is started, 8 COM ports are created:


  1. After VCOM service is started, then you start VCOM application, the application could NOT show all the 8 modems and 8 COM ports:
    VCOM application must be closed.
  2. If you want VCOM application to show all modems, then you must first stop the VCOM service, the only start VCOM application.
  3. VCOM cannot be running as both Windows ApplicationĀ and Windows Service mode at the same time.
