Installation Error. Cannot Start Application.
Answer ID 8704   |   Last Review Date 02/25/2019

When installing, why are we are getting the error, "Cannot continue. The application is improperly formatted."?


Oracle B2C Service, All supported versions


To remedy this issue, have the agent manually delete the following folder C:\Users\<USER_NAME>\AppData\Local\Apps\2.0\. if it exists.

Then reboot the workstation and install any pending Microsoft updates before installing the Oracle B2C Service application.

PLEASE NOTE: If the folder C:\Users\<USER_NAME>\AppData\Local\Apps\2.0\ is not visible in Windows Explorer, please enable viewing of system and hidden files.

If the issue persists, please contact Oracle B2C Service Technical Support via Ask Technical Support.


This problem occurs when the ClickOnce installer does not recognize a chained certificate as a valid Authenticode certificate. This is most often is due to a .NET problem,  pending updates from Microsoft needing to be installed, or web browser settings blocking the install.
