Hi, If the Excel 2010 worked fine before, I would like suggest you find the installation of update: Get details from Control panel > Windows update > View update history or view the C:\Windows\WindowsUpdate.log Remove the update installed and restart computer. In addition, please post thread in the Office forum for more information: Office 2010 Setup and Deployment http://social.technet.microsoft.com/Forums/en-us/officesetupdeploy/threads Best Regards, Yan LiYan Li TechNet Community Support

I have a training server with Office 2010 installed. This is a new machine and at random times I have received the following error. Excel is not open when this happens and I have not find a solution that applies to windows server 2008. The machine has all the latest updates, and looking at the hhctrl.ocx file, it seems to be the original file and not have been modified by updates. Thank you. Faulting application name: EXCEL.EXE, version: 14.0.6106.5005, time stamp: 0x4e26f27d Faulting module name: hhctrl.ocx_unloaded, version: 0.0.0.0, time stamp: 0x4a5bd9ea Exception code: 0xc0000005 Fault offset: 0x041d473f Faulting process id: 0x1f30 Faulting application start time: 0x01ccba99bc6b97bb Faulting application path: C:\Program Files (x86)\Microsoft Office\Office14\EXCEL.EXE Faulting module path: hhctrl.ocx Report Id: e2b53e81-269f-11e1-8162-0050562dafaf
