A Problem with Install Shield

Recommended Posts

I am making my own install shield executable that is supposed to delete the previously installed program during the installation process. This happens sometimes. http://i67.photobucket.com/albums/h292/Athono/ocassional_error.png What causes an install to produce this error? Does anyone know what I am supposed to do in InstallShield to prevent this from happening?

There are two ways of doing this properly. The first is to force an uninstall of the first product. The other way is to do an upgrade. Just over writing the files is a bad idea.
