I have a client with Office 2010 Home & Business. They are having a weird problem with Excel.
A domain admin does not have the problem described here while a domain user does.
Launching Excel then Opening a file works fine; however, double clicking on a spreadsheet returns the message: “This action is only valid for products that are currently installed”.
The product is activated.
I have performed a Repair to Office, followed by a reboot
I have removed Office, rebooted, reinstalled Office, rebooted. This issue seems fairly consistent.
Any ideas what to try next?
