ETOOLBOX CAD Viewer for Windows desktop requires license registration/activation. A license can be obtained for free at https://www.intellicadms.com/store/standalone

After install and run, ETOOLBOX should prompt for license registration. 15 days trial period is available hitting the "Register later" button.

Use the license ACTIVATION KEY listed at the LICENSES webpage of https://www.intellicadms.com

To transfer the license from a licensed system to another one, run ETOOLBOX CAD Viewer and click the "i" information button > manage license > insert the activation key > click DEACTIVATE button.

I did this, the downloaded Intellicad 9.2 and installed it, but it does not work. First of all it didnt ask me for an activation key.
Despite of that I can open the program, and open some dwg files, but after I work on them and try to save or save as, the program crashes. Every time the same, I have uninstalled it and installed it back like 10 times. i even deactivated Norton AV thinking that it might be causing problems.

I am desperate, this is a working tool for me at my job....

what can I do?

To deactivate the CMS IntelliCAD license you can find instructions at the download page of https://intellicadms.com

Basically, it's very simply. At the licensed system (still running the CMS IntelliCAD license) you need to go to HELP > License Manager and then select "deactivate".
This action will release the license automatically to allow a new activation (at a supported system).
