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 -
  <data name="axToolbarControl1.OcxState" mimetype="application/x-microsoft.net.object.binary.base64">

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.
