Note to users running under Windows 7:
It is suggested to not install the Solex package in the defauld
folder proposed by the installation program, i.e. C:\Program
Files\Solex110, because in this case the standard Windows protection system
will prevent files to be written to the subdirectory USERDATA of the Solex110
folder, writing them somewhere else in your hard drive.
This inconvenience might be avoided by starting the Solex programs using
"administrator" privileges, but a better idea could be to install the package
in some unprotected custom folder of your choice, such as for example C:\Astronomy\Solex110\
