When closing ideCAD it says "Access denied. Possible cause File is read only" what can I do?

Close ideCAD.

Delete the C:\ProgramData\ideCAD10 folder.

If you can't see the ProgramData folder, it may be in a hidden location. You can make it visible by checking the "Show hidden files, folders and drives" option in the "Advanced settings" section.

Hold down the Ctrl + Shift key on the left of the keyboard and run ideCAD from the desktop shortcut.

Keep pressing the Ctrl + Shift keys until you see a message saying "Registry entry and settings are cleared" .

The message may remain in the background. Observe the message that appears.

Click the OK button to close the dialog. When the program opens, load your project and try again.
