What version of windows are you using? If you are using Windows Vista, 7, 8, 8.1 or 10, then you can not save files in the C:\Program Files (x86)\ImageEn\DelphiXE7 folder. Move the imageen source files and demo files to a new folder. Generally I install all components to a base folder called C:\Components... so ImageEn would be installed in C:\Components\ImageEn and demos would be in C:\Components\ImageEn\Demos folder.
Once you move the existing ImageEn files recompile the ImageEn packages or rerun the installer but this time select C:\Components\ImageEn when prompted by the installer.
For each project I save them to C:\Projects\xxx with xxx being a subfolder for each project.
This is not a problem with ImageEn... it is a problem with every version of windows since XP. It is called User Account Control or UAC for short.
Only installer applications can write files to C:\Program Files (x86) folder.
