Description:

When opening HydraCalc v50, you get Run-time error '13' Type mismatch OK

The calc program will open but you cannot open any jobs or do anything in the window.

Cause:

Regional settings issue, the character used to indicate decimals is a comma instead of a period.

Solution:

Open the Control Panel and go to 'Clock and Region'

Select "Horloge et Région / Clock and Region"

Select "Région / Region"

Select "Paramèters supplémentaires / Additional settings"

Change "Symbole décimal / Decimal symbol" to a period.

Click OK back through the windows to save your changes.
