Frequently Asked Questions
I am currently in the process of compiling a range of questions that are regularly asked about Perfect Lite. When done I will include them on this page with the relevant answers.
In the meantime, if you have any specific questions then please contact me on feedback@perfectlite.com and I will promptly get back to you.
-
Will Perfect Lite function under Vista/Windows 7?
-
Do I have the latest version of the Perfect Lite software?
-
How do I determine the Serial No. and Version No. of the software I have purchased
Perfect Lite [i.e. DOS application]
P Category Lighting and V Category Lighting software [i.e. Windows application]
-
After installing the V Category Lighting software and running the new program I get an error message "Cannot find the file Plusers.ser"
You will find a copy of this file in the 'c:\ple' folder on your computer, simply copy this file into the 'c:\Program Files\Perfect Lite' folder and re-start the program. If you can't find the file or program still does not operate send an email to support@perfectlite.com
-
After installing the V Category Lighting software and running the new program I get an error message "Cannot find file 'SAADAT', Mode 2 default values used."
This error is not critical and should only occur the first time you run the software (or at least until you do your first Spacing calculation).
-
When you run the Pedestrian Area Lighting software and select to produce a Local Road or Pathway spacing table and you get an error message referring to "COMCTL32.OCX not found or missing" or "Out of Memory".
You need to download the 'Comctl32.ocx' file and save in your c:\Windows\System or c:\Windows\System32 folder. Click here to download the file (608Kb).
- When running Perfect Lite through the CEPLE AutoCAD Interface and it does return to AutoCAD (i.e. message "Waiting for Perfect Lite..." remains on the screen)
Start up into Windows Explorer and delete the CEPLE.BAT file from the folder containing the Perfect Lite software (ie. location of file PLE.EXE - usually in the 'c:\ple' folder ). This will immediately returns you to AutoCAD.

- Does Perfect Lite run under the Windows operating system?
As you probably know Perfect Lite is largely a DOS application (except for the P Category & V Category modules). A recent upgrade to Perfect Lite (version 4.86) now allows it to run successfully on the following versions of Windows:-
- Windows 95
- Windows 98 & 98 Second Edition
- Windows NT
- Windows 2000 Professional
- Windows XP Professional
- Windows XP Home (some limitations apply)
The program does not run successfully on Windows ME!
- Why won't Perfect Lite print to my newly purchased Inkjet printer?
The current range of Bubblejet/Deskjet/Inkjet printers on the market generally do not have DOS drivers as they are meant to only print from Windows Applications. As the main module of Perfect Lite is a DOS application printing has become a problem. However, Version 4.84 (onwards) now has the facility to print via the Windows Print Manager overcoming this problem & in some ways even simplifying the identification of the printer in Perfect Lite.
- Will Perfect Lite run on a Network?
Perfect Lite can be loaded on and run from a Network drive. However, the software will only allow one user to run the the software at a time. If you have a large office and are likely to have more than one user wanting to run the software then your best option is to purchase additional copies of the software.
- When will Perfect Lite be converted to a Windows application?
Conversion of Perfect Lite from a DOS application to a GUI Windows application has commenced. Due to the size of the software it will be carried out in several stages. To date the following modules have been converted:-
P Category Lighting software
V Category Lighting software
- Is photometric I-table data for various luminaires provided with Perfect Lite?
Twenty (20) sample luminaires are provided with Perfect Lite for evaluation purposes only. It is up to the purchaser of the software to obtain photometric I-table data from the various manufacturers and load them into the Library files maintained by the program. This data is usually readily available on disk.
- Is the SAASTAN.EXE program provided with the V Category Lighting software?
SAASTAN.EXE is a program included as part of AS1158.2 - 1986 (Public Lighting Code) distributed by Standards Australia. The V Category Lighting software requires this program to operate fully but I do not provide it as part of the Perfect Lite package.
