Error Code: 0x800700c1 suggests that an incorrect DLL mapping exists for the handler referenced in the error, confirm that the correct ISAPI dll is selected for the handler mentioned.
Error code 500 0 193 can be translated as " ERROR_BAD_EXE_FORMAT " which can be addressed by applying the correct value in the "Path" field as explained in step 4 of the solution included below.
To address this apply the following:
1. Launch IIS Manager and select the EVBAAdmin Virtual directory.
2. Open the Handler Mappings object in the properties of the virtual directory, in this instance AboMapperCustom-XXXXX.
3. Review the entry for the handler in question and confirm the C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll is mapped.
4. Confirm that the "Path" field for the mapper is configured to the correct EXE type. If the "Path" field shows *. then change it to *.asp.
5. Stop the Enterprise Vault Accelerator Manager Service (EVAMS).
6. Restart IIS by typing IISRESET into a RUN box or into a Command Prompt and pressing enter.
7. After IIS has been restarted, start the EVAMS and test access to the EVBAAdmin page.
