Thanks for bringing this to our attention. We are struggling to reproduce this error, so the first step is to reinstall ClinicOffice on that computer as it might be missing a component which is causing the error. You can download the full setup file via the link below.


After you have installed this, please retest the diary print preview. If you are still receiving the error message, please could you provide us with the settings that you use? For example, when you go to print preview, what time range do you select (whole day, morning appointments..)? Do you have the appointments in-room or staff view? How many staff/rooms do you have selected?

The above information will help us to reproduce this problem and many thanks in advance.
