During installation, Spreadsheet Add-in is automatically registered with Excel and included in the Windows registry entries.
You may unregister Spreadsheet Add-in from Excel. Unregistering clears the registry entries and removes the Essbase menu from Excel; however, it leaves the Spreadsheet Add-in components on your computer.
To put the Spreadsheet Add-in back into Excel, you can run the register program manually.
To manually register Spreadsheet Add-in, select Start, then Programs, then Oracle EPM System, then Essbase, then Essbase Client, and then Register Spreadsheet Add-in.
To unregister Spreadsheet Add-in, select Start, then Programs, then Oracle EPM System, then Essbase, then Essbase Client, and then Unregister Spreadsheet Add-in.
