  • LitioLAB.cfg
  • LitioLAB.dat

Additional Information

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.
