The version number in the package is not valid

Both versions of BIDS installed gives an error. 

The new SSIS gig fully underway, and I happened upon an error that I'd never seen before, so wanted to write it down.  You might get the following when developing SSIS and calling .dtsx files from DTEXEC locally: 

Description: The version number in the package is not valid. The version number cannot be greater than current version number.

This is due to the fact that you have installed both versions of BIDS installed locally, and you must specify the .exe that you want to be fired when calling DTEXEC because there are two versions on your system.  Either that or simply rename or remove the older version  (if you are not going to use it again).  

 Simply specify the entire path of the .exe at the command line and it should work for you: "C:\Program Files\Microsoft SQL Server\100\DTS\Binn\DTExec.exe" like so:

Happy SSIS'ing!
