Version number format error

I would like my project to have its version numbers in the 1.2.3.4
format; however, whenever I change the "version" property in my setup
deployment project I get this error
"C:\myprogram\Setup_Projects\xyz\Setup - xyz.vdproj Invalid product
version '1.2.3.4'. Must be of format '##.##.####'

It does accept a version number with only two decimal points: 1.2.34

However, my company would like to see a four number format version
number: 1.2.3.4

which I thought was a Microsoft standard.

I also changed the AssemblyInfo.vb to:

<Assembly: AssemblyVersion("1.2.3.4")>

but it didn't make any difference.

thanks,
