The type initializer for Flexera.BusinessImport.BusinessImporterCryptographer threw an exception.
When trying to use the Encrypt Connection Information option on Business Adapter Studio 2014 R2 or later and save the file, "The type initializer for Flexera.BusinessImport.BusinessImporterCryptographer" is shown in the UI dialog.
Business Importer tries to create an encryption key under HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ManageSoft Corp\ManageSoft with string value MGSBI and it prevents ordinary users from executing the import with encryption.
Running the Business Adapter Studio with admin rights stops this error.
This problem has been reported as a bug (IOJ-1720238).
