To start LitioLAB 1.0 type LITIOLAB on the command line or click on the ribbon button

First, choose the standard drawing tool (dialog 1/2), or

go to the Advanced math tools - Graphs (dialog 2/2), and choose the right tool for you.

You can also click one of the buttons:

• XLS to Points: to paste XLS coordinate data as AutoCAD entities
• Load LLP: loads an existing LLP (LitioLAB project) file containing all math function data, and opens the respective dialog for further editing or to proceed to graph creation.
• Settings: goes to the Settings dialog

The installer that runs when you downloaded this app/plug-in from Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin. You may need to restart the Autodesk product to activate the app/plug-in. To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button. OR, click Control Panel > Programs > Programs and Features (Windows 7/8.1/10/11) and uninstall as you would any other application from your system.

LitioLAB can be manually installed by placing ALL of the LitioLAB 1.0 files in the "SUPPORT" directory of AutoCAD:

• LitioLAB.slb
• LitioLAB.dcl
• LitioLAB.vlx
• LitioLAB.cfg
• LitioLAB.dat

Alternate Installation (for Autodesk App Store downloads):

LitioLAB 1.0 can also be installed by executing the installer file, which is available at the Autodesk App Store. The installer will install LitioLAB 1.0 to the Programdata\Autodesk\ApplicationPlugins folder. 

In some operating systems, to run LitioLAB 1.0 your user needs to have the permissions or privileges, to access, write or modify files in the folder where LitioLAB 1.0 files are located (e.g., the SUPPORT folder). LitioLAB 1.0 modifies the LitioLAB.cfg file when you make LitioLAB 1.0 configuration [settings] changes. (LitioLAB 1.0 may need to create/modify other files in normal operation.)

To solve this problem, you need to be logged in as an administrator, and/or, you need to get the necessary permissions or privileges: right-click the folder, properties, security tab, give permissions. (If not, when making configuration [settings] changes, they will not have any effect, and LitioLAB 1.0 might crash).

Another solution is to place all LITIOLAB.* files in a directory (folder) you have permissions to modify, and add the folder to your CAD's support files search path.
