Dear Gurus! I wrote previous program on c# under vs 2005, using arcgis Engine 9.3. Now I have 64-bit - computer and work on vs 2010 with arcengine 10.0. I have convert program from vs 2005 to vs 2010 and from arcgis 2010 to vs 2010 with standart instruments. But now when running program , I have error message:Error 1 unload "file:///C:/Program Files (x86)/ArcGIS/DeveloperKit10.0/DotNet/ESRI.ArcGIS.ADF.dll" or one of dependent components because of wrong format . Error was on next string - AAEAAAD/////AQAAAAAAAAAMAgAAA... The original version was in 32-bit computer , and target platform - x86, and target framework - .Net framework 2.0. In converted version I leave the previous settings. May anybody help to solve problem? Thanks in advance! PS. On 32-bit computer the program after converting work normally.

ESRI does not support the 4.0 framework until 10.1 and then only optionally.

3.5 is the one you seek.

Thank you very much!
And what about target framework? Can it be 2.0, when I use arcobjects 2010? Or must be target framework 4.0?

Set the project to build x86.  You can't build a 64 bit (or AnyCPU) executable image which references ESRI assemblies (which are 32 bit only).
