Installing extensions from supported Oracle Fusion Cloud Enterprise Performance Management services involves downloading an extension installer file and double-clicking it. When double-clicking an extension installer (.svext), a message window is displayed indicating the success or failure of the installation. The message window can sometimes lose focus and go behind another open window, and can easily go unnoticed. This may lead to users trying to install the extension again, causing an error due to the previous open message window having a hold on the folder and files.

To clean up this extension installation issue:

1. Close all Office applications (Excel, Word, PowerPoint, Outlook).

2. Check the Windows task bar for an existing message window, and close it.

3. Remove prior extension installations:

   1. Navigate to %AppData%\Oracle\SmartView\extensions\bin

   2. Delete the extension folder.

      For example, to delete the Narrative Reporting extension folder, delete the Oracle.SmartView.EPRCSExtension folder.

   3. Delete the extension installation folder.

      For example, to delete the Narrative Reporting extension installation folder, delete the EPRCSProviderInstaller folder.

4. Remove pending installations:

   1. Navigate to %AppData%\Oracle\SmartView\extensions\update

   2. Delete the pending extension installation folder.

      For example, to delete the Narrative Reporting pending extension installation folder, then delete the Oracle.SmartView.EPRCSExtension folder.

5. Return to the location where you previously downloaded the extension installer file, and double-click it.

   For example, to install the Narrative Reporting extension, double-click EPRCSProviderInstaller.svext.

6. Open Excel, Word, or PowerPoint, and in the Smart View ribbon, click Options, then select Extensions, and then verify that the extension you installed is listed.
