I have written commercial software that accumulates data from a pilot installation and saves this (in a nutshell). It works all well, HOWEVER when someone has a windows version with different regional settings it saves data with a comma as decimal separator instead of a period. E.g. 3,14 instead of 3.14
This becomes a problem when interpreting data, as I save data in a .csv file with, yes, a comma as delimiter.
So what I want: Include in the installer a registry key or something else that will automatically change this on windows 7/vista if the user has different settings.
How can I achieve this.
