2012 'Could not load file or assembly 'ManagedMapApi.dll'...

[Anonymous]

Hi, I keep getting the above error when trying to run a custom form in my .Net custom code that uses the ManagedMapApi.dll.  I'm upgrading from AutoCAD Map 3D 2011 to 2012.  In 2011 everything works fine but in 2012 it gives this error.

I've looked and there is a C:\Program Files\Autodesk\AutoCAD Map 3D 2012\ManagedMapApi.dll just like in the 2011 version.  I've tried referencing the one in the 2011 folder as well as the 2012 folder.  I've changed it from Copy Local -> False to Copy Local -> True and back again with no luck.  I've also tried running all these changes on a computer with just AutoCAD Map 3D 2012 and no 2011 installed on it.  I've tried it with No service pack upgrades, SP1 and SP2 and still no luck.

Any help would be appreciated, thanks.

Hi,

not checked that now, but I'm quite sure that this was repaired in one of the service-packs for Map3D.

Thanks for the reply, I have SP2 installed on both machines and have referenced the ManagedMapApi.dll from the AutoDesk folder after SP2 was installed.

Hi,

can you copy the hole content of the messages (of your error-dialog visible in your screenshot) to a text-file and upload this here?

BTW: why does your app create an exception while Map3D is loading? If you have it set to be loaded while startup then undo this change and try to load your app after Map3D has finished initialization.

So even when I try to do a netload and then find the ManagedMapApi.dll in C:\Program Files\Autodesk\AutoCAD Map 3D 2012\ManagedMapApi.dll it gives me the following error, however when I do the same in Map 2011 it properly loads ManagedMapApi.dll with no error. It also gives this error on two different installs of Map 3D 2012 so it's not because of a random install problem.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this

The application must also be compiled with debugging

Hi,

what happens if you create a small new project just referencing the dll and create a function that uses a small part of this lib.

Do you then also get an error?

I see the second part of the message more important than the first as I don't think that you have a defect ManagedMapApi.dll (as you have done a full installation and you have upgraded all servicepacks for Map3D). So loading of this dll seems to miss some other parts to be able to get initialized. And maybe that you miss some support-paths in Map? E.g. to the directories with the FDO-bin's? Verify that or start with an AutoCAD-profile that is original or that you import from another pc or create a new Windows-user and try it within his environment (to build your sample project).

Thank you it did have to do with FDO->Bin directory.  My custom profile was set to install location \FDO\Bin for Map 3D 2011, however for some reason this was change for Map 3D 2012 to \bin\fdo... Extremely annoying as I had it based on install location and everything seemed to be changing correctly for 2012.

Thanks again for the help.
