We have systems running in windows XP that are not recognizing the
"NETLOAD" Command. We have tried to update the NET 4 and that did not
help. We have one XP system that loaded it fine but have not been able
to do it on other machines? Any thoughts?

Why do not you take your computer to the software expert... He can easily install that software into your computer....!! May be there is some manufacturing problem with the software or it may not be matching with the compatibility of the hardware of your system. 

Microsoft has a specific procedure for installing .NET as I am sure you are aware.  Did you follow that procedure exactly?

Yes we followed the procedure recommended by the software export. He told us it was a CAD issue not a microsoft issue.

Personally I think you should be using .NET Framework 3.5 Service Pack 1 not 4.  I think your computer expert is ill-informed.  Anyway, it does not surprise me that he pointed the finger at AutoCAD.  You do know .NET Framework is a Microsoft product right?I asked you if you followed AutoDesk's recommended advice not your so-called software expert.  There is a BIG difference between the two.John Connor2011-08-18 17:33:15

Windows XP?  Did you keep your version of Windows current with all service packs and updates?  Were you ever prompted to install the Windows Imaging Component (WIC)?

Thanks John.  Here is the deal.  We loaded AutoCAD per specs. On our Windows 7 machines we found that we needed to have .NET framework 4.0 to get this particular .dll to run. Not sure if it would be different on xp machines. Here is the mind boggler. We have a couple of XP machines that work and several that don't.  We have tried to mimic everything on the ones that work and no go. When I type in netload and browse to the folder and select the .dll it doesn't even give me an error just acts like I didn't even enter the command. I think I am running out of options and may be forced to us only windows 7.

Find and open your acad.exe.config file (can be opened with Notepad) and see if it looks like this:<configuration>  <startup useLegacyV2RuntimeActivationPolicy="true">    <supportedRuntime version="v4.0"/>  </startup><!--All assemblies in AutoCAD are fully trusted so there's no point generating publisher evidence-->   <runtime>            <generatePublisherEvidence enabled="false"/>       </runtime></configuration>
