Note to users outside of the USA
Early versions of AQUATOX required the decimal symbol, within Control Panel > Regional Settings > Number be set to a period. AQUATOX was not able to work with the comma as the decimal notation at that time. We resolved that problem in Release 2.1 (and later) of AQUATOX.
If you are a Release 2 user, and you get the following example error messages, check the regional settings to make sure that the decimal notation is not set to a comma:
File predates version 1.03
when attempting to open a study file, or
2.00 is not a valid floating point value
when attempting to run a simulation.
