Installing with or without administrator privileges

To create the installer for Task Coach on Windows, I use the excellent Innosetup tool. I upgraded to the latest version of Innosetup a while ago but didn't notice immediately that the installer created by this new version of Innosetup required the user to have administrator privileges. Because Task Coach is aimed at ordinary users, that is not acceptable.

It took me some time to find out how to have the installer work for both users with and without administrator privileges. I'm recording the solution here so that other developers may benefit from it.

In the registry section of the Innosetup script I included two versions of the lines that associate the ".tsk" extension with Task Coach. The first four lines (*) are used if the user has administrator privileges (Check: IsAdminLoggedOn), but the last four lines are used if the user has no administrator rights (Check: not IsAdminLoggedOn).

(*) I had to split the lines to prevent them from being clipped. The line continuations are indented.

is there a way to use this on a jailbroken ipod touch?

No, Task Coach is only available for computers running Windows, Mac OSX or Linux.

Cheers, Frank

Cheers for the great program, I have been using it since 2006.

I use NSIS (http://nsis.sourceforge.net/) to create Windows installers, I've found it incredibly flexible and powerful.

I also use NSIS in my projects now. Inno is great, and I used it for a good while, but NSIS creates an msi that is much easier for end users to use.

Just my 2 cents. Love the program!
