I just built a new computer with Windows 7 Pro 64-bit and fully updated it. I then installed Office Professional Plus 2010 (32-bit). And fully updated it. After which I put in Office Project Professional 2007 and fully updated it. The issue is when I go to open a Project file it throws "There is a problem sending the command to the program" after acknowledging this error the program begins to open but does so dreadfully slowly. This computer has an Intel Pentium Dual core 3.2 GHz with 4 GB of RAM and a 100mbps Ethernet connection to the server hosting the project file. This issue did not occur on the previous computer that was doing this task. I've done a Google search for this error and all the results are for Excel 2010 nothing mentions Project. However Excel on this machine has no issues. Any ideas would be greatly appreciated as this really has me scratching my head. As time is money I'd really prefer to not have to rebuild this machine again if possible. Thanks!
