I just got a new Dell Latitude D830 laptop running Vista Ultimate and I'm going about the lengthy process of installing all my software. When I got to PowerShell, I grabbed a copy of the installation file from my 250GB external drive that I had previously downloaded for my previous laptop, a Dell Latitude D610, running Windows XP SP2.
When I ran the install program, I was repeated met with the following error message:
Not enough storage is available to process this command.
A lot of other people had the same problem, but no one had posted a solution. Then, I suspect I figured out the answer the same way others had. I was executing WindowsXP-KB926139-x86-ENU.exe instead of Windows6.0-KB928439-x86.msu, I had overlooked the fact that Windows XP and Vista had different installation programs for PowerShell.
Drat.
