I am trying to install Activstudio for Windows software version 3.6.14
(Promethean software for an interactive whiteboard) on a computer with
Windows XP. I get the following message:

Windows Installer
Invalid command line argument
Consult the Windows Installer SDK for detailed command line help.

I have never seen this message in the past when installing software on
this computer. I would appreciate any assistance that you might
provide so that I can load this software successfully.

Thanks,

Tom
