When I run the Orb setup program I get an NSIS error: "The installer you are trying to use is corrupted or incomplete...".

If you get the following NSIS error message: "The installer you are trying to use is corrupted or incomplete. This could be the result of a damaged disk, a failed download or a virus?", it is most likely caused by a data corruption in your download.

To correct this:

1.  Disable any download accelerator you may have installed on your PC

2.  Clear your browser cache:

In Internet Explorer: Tools > Internet Options... > Delete Files

In Firefox: Tools > Clear Private Data > check Cache > Clear Private Data Now

3.  Download the Orb setup program again, save the file to your hard drive, then run the Orb installation
     program again.
