OK so I have been playing around with vista for some time now but only ever installed the x86 build, so I thought it was about time to install x64, So my PC was needing a rebuild so I thought what the heck I'll throw Vista 64 bit on it 
. Well all went well and no problems were encountered. Most of my hardware was detected except my Sound Card but I managed to find a 64bit compatible driver.
Well Got vista installed and running, Installed office and then some other tools on it, next thing was to install the Admin Pack, so I did what I had posted earlier and that went ok. The next thing was the Exchange System Manager..... so I copied the files across and then tried to register the maildsmx.dll file. Tried being the right word! it would not register. After a couple of minutes thinking I started to think that our exchange system is 32 bit so the dll is more than likely 32 bit so I did a quick google and only found posts saying Exchange 2003 cannot be installed on a 64 bit environment. So I thought that I would cut my losses and re-install Vista as 32 bit.
So Here we go with a 32 bit install now
