Problems installing 2.7.3 on Windows x64

Hello Matt,

Thanks for letting us know about this problem. Windows x64 is not very
widely in use, so we have not received similar reports before.

In order to manually remove Scala, you can just delete the Scala directory
(in your case, C:\Program Files\Scala). That removes the main files added
by the installer.

You can then delete the menu item (if you chose to install that at
installation time): from the start menu, hover onto the "Scala 2.7.x" menu
item, right click, and select "delete" from the menu. A confirmation
message "Are you sure you want to delete Scala 2.7.x etc." should appear.
Select "Yes".

The two steps above will remove the installed files. A few environment
variables are also added by the installer; you can safely ignore them, as
they will have no effect. If you want to get rid of that as well, you can
follow these steps: please do not attempt this if you are unsure, as an
unskilled editing might affect the operation of your machine. To remove the
added variables, open the "System" control panel, click on the "Advanced"
tab, and then on "Environment Variables". You will see in the upper panel
(User Variables) the variables "SCALA_HOME" and "PATH". SCALA_HOME can be
deleted. The text ";%SCALA_HOME%\bin" can be removed from PATH; if PATH
only contains "%SCALA_HOME\bin", the user variable can be deleted altogether.

By following these steps you should be able to remove all traces of the
installed files.

We will look into upgrading IzPack, to add the missing Win64 functionality.
Thank you for letting us know about this problem.

Thanks for the uninstallation instructions. When I mentioned the DLL,
I was wondering if there might be a trick to getting 32-bit DLLs to
run on x64. For example, you can right-click on an executable and
then look in "Properties --> Compatibility" for options concerning
older versions of Windows. I thought there might be a slim chance of
something similar for DLLs, and in the reverse order (older --> newer
OS versions). However, those instructions are fine.

Thanks,
Matt
