If you are not running the latest version, we strongly suggest you download and install it to see
if the problem goes away.
Important! All versions earlier than 18.104.22.168 has expired and will no longer start.
Important note to Windows 7 users
There is an issue with older Windows versions together with the .NET Framework 4 causing the simulator to show an error message at start and then closing. This issue can be solved by simply downloading and installing the .NET Framwork 4.5 on the PC. If you are having this issue, please follow the link below to update your .NET Framework version to 4.5.
Make sure you have the right requirements to run the program.
The problem could also be caused by a corrupt setting, try this:
Double-click the CNCSimulator Pro icon and then quickly hold down the left ALT key on the keyboard.
Keep holding the ALT key down, after a few seconds, a small window will show.
Click the topmost button that says: "Reset program settings (incl. tools, workpieces etc)"
Be aware that this will completely reset all settings in the program and you will loose custom tools,
workpieces and other things. Now, try to restart the program again.
If you for some reason cannot use the reset method above you can also reset the settings from the command line.
Click on the start button and type CMD followed by Enter.
Type C: (or the drive letter of the drive where you have the simulator installed) end press Enter.
Type CD followed by the path the the folder where you have the simulator installed and press Enter.
Type cncsimulator.exe /ds and press Enter.
The simulator will now start and you should see this message:
Restart the program and check if the problem is solved.
If the simulator does not start at all and there are no error messages, try this:
On some computers with AVG Antivirus installed, the simulator gets blocked at start due to a bug
in AVG. This will hopefully soon be fixed but in the meantime, you can get around it by temporarily
disable AVG. Right click on the AVG icon in the task bar notification area and select "Temporarily
disable AVG protection". Now, try to start the simulator again.
You can read about this problem at AVG support.
Adding an exception as the AVG user did also solve this problem.
We expect AVG to solve this problem quickly.
If this did not solve the problem, also see this article.
If the problem persists, go to the installation folder of the CNCSimulator Pro and see if there are any
*.txt files there. For example "startupexception.txt" or "scripterrors.txt". If so, email these files to support
and we will try to solve the problem.
Remember to add as much information as you can. We need to know your Windows version, computer
configuration, CNCSimulator Pro version, when the problem started etc. Add screenshots if needed.
