Installer improvements

[ewieldra]

Hi Jeroen,

Thanks for MyDefrag ..

Could you change the installer to support uninstalling previous versions or change the installer to install into the same folder.

I believe there is also a bug 

For example install 4.1.1
after that install 4.1.2
remove one of the mydefrag installations from controlpanel

Then try to remove the other from the controlpanel

When you remove one of the installed versions the file associate is also removed ..

Installing an older version also overwrites a newer version of the screensaver.

The Inno Setup compiler that I am using does not support uninstall when installing a new version.

or change the installer to install into the same folder.

If you have made custom scripts then you will want a copy of the MyDefrag program for which you developed the script. If you don't like the default installation directory then simply change it (you can select it when installing).

When you remove one of the installed versions the file associate is also removed ..

Yes, will be fixed in the next version.

Installing an older version also overwrites a newer version of the screensaver.

Sorry, can't be helped. The last installed version is the active version.

I believe Inno setup support uninstalling previous versions or updating previous versions..
It has something to do with AppId/AppName it's the same for U3 applications

You can do a filecheck with inno setup .. for example to prevent overwriting certain files even give the people the choice to overwrite..
