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.
Run-time error '62': Input past end of file
This error can occur when starting the PlePcat or PleVcat software if the Activation files (eg. Serial.num & Plusers.ser) have been corrupted. This sometimes happens when the files are provided to you via email. If this occurs, simply contact me for re-issue of the files, advise of your software serial number.
Will Perfect Lite function under the Vista or Windows 7 operating system?
Will Perfect Lite run on 64-bit computers?
Perfect Lite is not designed or supported for the 64-bit computing environment. However, I have been told that the Windows applications seems to install & operate when run in the XP Mode of Windows 7. The following link may assist:-
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
How do I add luminaires into the Perfect Lite Luminaire Library?Input of I-tables into PLE.pdf
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 P Category 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).
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.

As you probably know Perfect Lite is a16-bit DOS application (except for the P Category, V Category & photometric data conversion modules). A recent upgrade to Perfect Lite (version 4.89) 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)
- Windows Vista (some limitations apply) Click here to find out more
- Windows 7 (some limitations apply) Click here to find out more
The program does not run successfully on Windows ME! or ANY 64-bit PC
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.
Perfect Lite can be loaded on and run from a Network drive. However, the software must only be run by one user at a time (this should be 'locked down' by the Administrator). The software is not Network aware so if more than one users tries to use it a time then the results will be un-predictable & may lock up the computer.
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. In this case, the software can be installed in different network folders or on individual PCs.
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
IESNA to CIE/SAASTAN photometric conversion
CIE/SAASTAN to IESNA photometric conversion
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.
SAASTAN.EXE is a program included as part of AS1158.2 - 1986 & AS/NZS1158.2:1999 (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.
