ChemLab v2.0e Evaluation Version requires Windows 95/98/ME, Windows NT 3.51 or higher.

(build 37 - March 16, 2001) 

Model ChemLab 2.0 requires Windows 9x, Windows NT 3.51 or higher to run. 
(MAC OS versions also available)


ChemLab is installed with an InstallShield self-extracting install program: setupex.exe
Executing setup.exe will start the install process and add a "ChemLab" menu to your 
start Programs menu.


Running chemlab.exe from windows 9x and NT4.0 

1. Click the Windows Start button, and then point to Programs. 
2. Select the ChemLab program in the ChemLab program group.*
2. When ChemLab starts pick a simulation module to load from the simulation dialogbox. 
3. Read the lab introduction in the introduction text window. 
4. After reading the lab introduction read the procedure. 
5. Select the procedure tab above the text window. 
6. Then perform the lab following the steps in the procedure. 

While performing the procedure you can record your observations in the observation text window.

*ChemLab may also be run by double clicking on the ChemLab.exe file found in the ChemLab 
program folder (c:\program files\Model Science\ChemLab\chemLab.exe)



Creating a UDL, with  the lab wizard involves the following steps:

1.  Select the ChemLab Wizard from the simulation dialog box (simulation dialogbox, 
	appears at startup or when the users specifies new reaction)
2.  From the File menu select "Create UDL..." menu.
3.  Lab Introduction dialog, displays copyright information (read and select Next) 
4.  Lab Information dialog, specify the File Name, Lab title and short lab 
	description (this information will appear later in the simulation dialogbox) 
	(fill in and select Next)
5.  Lab Documentation dialog, user specifies the introduction, procedure and results, 
	RTF (Rich Text Format)  files. To create these files user should first run Word or 
	other word processor and save the files in an RTF format. 
	(fill in all fields and select Next)
6.  Available chemicals dialog, the user specifies chemicals required for their lab from 
	a database of available chemicals.  
7.  The user may also add to or modify the chemical database, as they need to. 
8.  Modifying the properties of Added Chemicals. Once chemicals are added from the 
	chemical database, their properties may be modified, this allows chemicals to be 
	marked as products or reactants (reactants will appear in the chemicals dialogbox within ChemLab). 
	(Add all chemicals and select Next)
9.  Reaction dialog, the user specifies reactions list. Start adding reactions by 
	selecting the "Add Reaction button". A reaction detail dialog will appear. 
	Name reaction and set any reaction conditions. A new entry will appear in 
	Reaction Tree. Drag and Drop Chemicals from the Available Chemical List to the 
	leaf nodes labeled "Reactants" and "Products". 
10.  A reaction chemical dialogbox will appear if successfully dropped, fill in the 
	coefficient for the chemical. Continue to drag and drop until you have the 
	complete balanced reaction. Once all the reactions have been added, select Next.
11.  Finish dialog, this is the last step in lab creation process, select Finish and 
	the UDL will be created (file.udl) in the ChemLab directory.
12.  Close and restart ChemLab, select your newly created lab from the Simulation dialog.


NOTE: The UDL(s) created with the evaluation version are not saved to file.

Known Problem: 

The Updated Windows Common Control version 4.72:

Windows 95 and NT 4.0 users may experience a problem viewing the complete list of ChemLab 
simulations in the Lab Module DialogBox (see list of simulation modules at end of this file). 
This is likely due to an older Windows common control file (comctl32.dll) being present. 

Do not install if using Win98.

This control is also updated when IE4.0 is installed. 

Available from:

http://msdn.microsoft.com/developer/downloads/files/40Comupd.htm

Note: it will be necessary for users to reboot before utilizing this control. 

To check the version of your common control file:

Go to your Windows\System directory.
Right Mouse click on comctl32.dll file
Select Properties from Menu
Select Version tab and version
If you have a version older than 4.72 you may wish to install update file...
 


Some useful Tips:

1. The Right mouse button brings up a popup context menu when clicked on the lab window.

2. Ctrl + left or right arrow key changes the selection of lab equipment. 
   The Lab window must have the keyboard focus; click the right mouse key on the lab window.
