Hi,

I had my sharepoint 2013 foundation with sharepoint-SQL reporting services integrated removed from my server 2012. And I removed my sharepoint folders and regedit files for sharepoint manually to ensure complete uninstallation of sharepoint from my server. But now I did a reisntall of sharepoint and it works completely fine, but when I tried to install the reporting services again I cant as it says it is already installed but the service is not listed in my sharepoint Services list and when i tried removing the reporting service using the SQL installer from control panel it exits with an error

Action required:
Use the following information to resolve the error, and then, try to uninstall this feature again.

Feature failure reason:
An error occurred during the setup process of the feature.

Install the sharepoint reporting services add-in to the exact same drive where you installed it before using the MSSQL installation file, now uninstall the add-in and the reporting service feature from the control panel. This will remove the corrupted files completely and now do a fresh installation
