Advanced continuous monitoring/audit programs one might reach the point wherein you want to to execute ACL scripts after hours.  This is rather easy to do:

You need to have three pieces of information:  The path to the project, the path to ACL, and name to the project and the script to be executed.

To schedule a project, you need to open the task scheduler.  The task scheduler can be found via by clicking on start button, selecting the accessories folder.  In the accessories folder, you should see a sub-folder for System Tools, select that folder.  Within the System Tools folder, you will see a button for "task scheduler".  Select this button.

The exact sequence of questions you will be asked depends on the version of Microsoft that you have, but you will be asked to provide a name for the task, a frequency, the time the task should be executed, and what is to be performed.  You will also be asked what you want to perform.

Depending upon the version of Microsoft, the utility will be more or less friendly.  Some versions will provide icons for your executables (ACL) that allow you to click on an ACL icon and the task scheduler will identify the path automatically for the software.  Other version will require you to find the executable via the BROWSE function.  In both cases, you need to find ACL and tell the task scheduler that you want to run ACL.

The Task Scheduler should provide the path for your version of ACLwin.EXE.  You will need to add an empty space, followed by the the path to the project in double quotes.  Finally, you will need to add a /b plus the name of the script. For example suppose you had the following:

Suppose your ACL program is located at C:\Programs\ACL\ACLwin.exe
Your ACL project is located at C:\ACLproject\
The script you wish to execute in the project is: A01_start

The syntax you would look for is:

C:\Programs\ACL\ACLwin.exe "C:\ACLproject\"/bA01_start
or
"C:\Programs\ACL\ACLwin.exe" "C:\ACLproject\"/bA01_start

You can test the exact parameters by running them from a BAT file or in the CMD command line.
