### Step 1: Install PC-DMIS Portable for Leica

1. Connect your port lock (dongle) to your USB port. The portlock must be present during PC-DMIS installation.

2. Execute setup.exe from the PC-DMIS Installation CD. Follow the on-screen instructions.

- If Leica interface is programmed in your portlock, PC-DMIS will load and use the Leica interface when working on-line.

- If All interfaces is programmed in your portlock (like a demo dongle), you may need to manually rename Leica.dll to interfac.dll. Leica.dll is found in the PC-DMIS install directory.

3. Copy a shortcut of PC-DMIS online and modify its target as follows:

For 6dof Capable Trackers (AT901):

C:\<PC_DMIS_INSTALL_DIRECTORY>\PCDLRN.exe" /portable:LEICA

For 3D Trackers (AT401):

C:\<PC_DMIS_INSTALL_DIRECTORY>\PCDLRN.exe" /portable:LEICARIO

This newly created shortcut will be used to launch PC-DMIS. This will open PC-DMIS with the additional Leica interface items. Do not launch PC-DMIS at this time.
