Hi all, Im getting pretty fed up with getting the same error messages when trying to install the trial of autocad. I have seen .NET Framework 3.5 under the control panel on my PC and have installed .Net framework 4. During the installation I keep getting a red X by .Net Framework 3.5 SP1.  DirectX 9.0 Runtime gets a green tick during installation however I get 5 alerts stating the following Error messages:AutoCAD 2010 Internal Error 2908 {9CBD4DFA-A2E4-405E-8FFB-6A4CEB9CBA3D}AutoCAD 2010 Internal Error 2908 {5EFBCC69-34A5-47258F6D98110A82B05B}AutoCAD 2010 Internal Error 2908 {A22E3DB9-BA62-4477-AF95-3189E7B06132}AutoCAD 2010 Internal Error 2908 {D6CC68E0-A5D6-43A7-B105-4FCFEF3745D6}AutoCAD 2010 Internal Error 2908 {8792605A-AB16-4D2B-9718-76564419254} What the hell do these mean!? Ive Googled them and nothing!  During the AutoCAD 2010 part of installation  the final alert  says the following:Error 1935. An error occured during the installation of assemble 'Autodesk.AutoCAD.Interop,version='17.1.51.0", publicKeyToken= "eed84259d7cbf30b",processsorArchitecture= "MSIL" '. Please refer to Help and Support for more information. I have just noticed after trying again the 17.1.51.0 part does change when trying again. I have no idea on what to do, someone please help as I have to use this for some work!! Thanks
