1-14 Section 1: Installation of Doors 01914-001 Rev. 5.5
9.0 Installation Maintenance
The following section provides information on verifying host computer system resources for optimum
program operation, for running a previous Doors installation, and for deleting a previous Doors
installation.
9.1 Verify Host Computer System Resources
Sporadic problems in operating the Doors program can be due to an inadequate amount of the host
computer's resources being available for use by Doors. The greater the number of programs open
concurrently, the less the amount of system resources available for any one program. Doors needs
approximately 65% of the computer system's resources free for proper operation. Perform the following
steps to verify system resources.
1. Click on the button on the Task Bar. A menu of selections appears.
2. Click on Settings ⇒ Control Panel.
3. When the Control Panel window appears, double-click on the System icon.
4. When the System Properties window appears, click on the Performance tab.
5. A list of system performance status values will appear; one of which is the system resources value.
6. The system resources value should be above 65% to ensure proper operation of the Doors program.
If it is not, close other unneeded programs to release the system resources they are using.
7. When you have finished viewing the system performance values, click on the OK button or click
on the box in the upper-right corner of the window.
8. If closing programs does not release enough system resources, close all programs, re-boot the host
computer, and then start the Doors program. This releases all system resources for reallocation.
9.2 Operating a Previous Doors Installation
At times following an upgrade installation, it might become necessary to revert to the previous
installation of Doors software. As the Doors installation wizard creates a unique directory for each
revision it installs of the Doors software, the previous revision is left intact. Operating the previous
Doors software revision is simply a matter of locating and running the correct Doors executable
program.
1. Open the Windows EXPLORER program.
2. Locate and click on the folder for the previous software revision (this is typically found in the
“c:\kerisys\Doors_vX.XX
1
” directory).

3. If the shortcut is visible, click on and drag the icon from the EXPLORER window to the
Windows desktop.
4. If the shortcut is not visible, right-click on the application file. A list of menu options
appears. Scroll through this list and click on the Create Shortcut menu option. A shortcut to the
previous installation of Doors is created and placed in the software folder.
5. Click on and drag the file from the EXPLORER window to the Windows desktop.
6. To run the previous installation of Doors, double-click on the Doors shortcut icon on the Windows
desktop.
NOTE: If you are downgrading from Doors 32-bit to Doors 16-bit software there are specific firmware
requirements for the master controller. Please contact your Keri Systems dealer for firmware revision
information.
1. X.XX refers to the revision of the Doors program.
2. Earlier versions of Doors may be found in the “c:\kerisys\Doors32_vX.XX” directory.
