The installation is simple. Run the SetupHeliSimRC program.
If you agree with the terms of the license, click Accept.
Decide which shortcuts you want installed, and click OK.
The installer will create a program directory called HeliSimRC, in the location you specify.
It will create subidrectories for the help files, data files, helicopter models, and canopies.
It will optionally create shortcuts to the program on your desktop and start menu.
No files are put in system directories.
No entries are made in the system registry.
Run HeliSimRC by double clicking the program itself, or one of the shortcuts created.
Removal
To remove the software, just delete the HeliSimRC directory, and all of its contents.
And, delete any shortcuts to the program.
Once again...
No files are put in system directories.
No DLLs are installed.
No entries are made or changed in the system registry.
So there will be no "debris" left over after removal.
