An error has occurred:
The type initializer for 'DacIEServiceCli.DataCenterMapper' threw an exception.
An error occurred creating the configuration section handler for DataCenterMapping: Request failed. (C:\Users\v-shmeht\Desktop\SQLAzureImportExportUtilities\BACPAC v1.2\DacIESvcCli.exe.Config line 25)
Sorry you are still having problems.
Line 25 is actually the DataCenterMapping tag. That makes me think something else is wrong. That section is for the DataCenterMapping configuration section.
Are you sure you updated the EXE and the config? If you grabbed it out of a ZIP, make sure you right clicked it, select properties, and select unblock. Otherwise it may not have permission to load the type.
What Operating System is this?
Just to verify, you have the full .Net 4 framework installed on this machine (not the Client Profile)?
Are you running this from a normal command prompt, or an administrator one? I don't think you would need admin level, but you could try it just in case. Launch the command prompt as administrator (you should see Administrator: in the title bar).
Where is your database located? Is it in a production datacenter (not a private cluster)?
