Installing XLL+ 7
Previous versions of XLL+
XLL+ 7 is not designed to run side-by-side with version 6
If you have XLL+ 6 installed on a machine, you will need to uninstall it before you can install XLL+ 7.
If you are an existing user of XLL+ 6, and you wish to test XLL+ version 7,
you should use a different computer, or set up a virtual machine.
Note that 64-bit Excel 2010 cannot co-exist on the same computer as any 32-bit version of Excel,
including older versions of Excel (Excel 2007, 2003 etc).
You should also note that Microsoft Virtual PC does not support 64-bit operating systems,
and cannot therefore be used to create a test machine for 64-bit Excel.
On desktop machines, Oracle's VirtualBox can be used for this purpose.
You must have administrative rights on the computer on which you
install XLL+ 7.
