This article provides resolutions to some common extension errors. 


My extension is compiling fine, but I can't launch the application from Visual Studio.


Error message from log file

Unable to load required module C:\Users\.....\SystemWeaver\Client\swExplorerExtensions\Systemite.SystemWeaver.Explorer.dll.

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.


Resolution

One cause for this error is the usage of the wrong version of the SystemWeaverExtensionsAPI. Confirm that you are using the correct version.

My extension will not load.


Error message from log file

Error loading module: Unable to instantiate managed plugin class "SWExtension.XXXXX". Most likely the type is not declared as "public", type or assembly are marked as ComVisible(false), or missing/incorrect license file is detected.


Resolution

One cause for this error is the usage of the wrong version of RemObjects Hydra. All extensions for the SystemWeaver client must use version 6.2.101.1237. See Prerequisites.
