How to open a CAL file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the CAL file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a CAL file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support CAL files. At this point we are looking for disk space where the application was installed in and we can link it with a CAL file. Since then, our operating system will use the selected program to support all CAL files.

Other issues

Despite the described problem with CAL there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the CAL file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the CAL file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
