Hello,
It is probably because it is the same program with minor changes that I install it over and did not swithch to new version or some other thing like this.
But when I run the install I get an error message (Le chemin "C:" contient un caractère invalide) and it end prematurely. And when I want to remove the last year program, there is also the same error message and I cannot get rid of this program anymore.
I need a little help to create programs that can update themself every once in a while without causing problem.
Thanks
Luc Michel

Hi,
Please note that a MSI package cannot update itself. If the package is already installed and it is run again it will go into Maintenance mode (Modify, Repair and Remove options).
However, if you run it from inside Advanced Installer, the installed package will be removed automatically (this is a feature of Advanced Installer).
If you want to remove a corrupted installation you can use the Windows Installer CleanUp utility.
