Excel/Outlook 2013 acting unusual

I installed a brand new Dell Win 7 Pro 64 bit desktop last week for a small client. They have a domain and a Win 2012 server and five Windows 7 Pro desktops. The new desktop is in the domain and runs all other applications perfectly.

On this new desktop. I installed Office 2013 which was purchased from dell with the system. I connected it to the client's Hosted Exchange and email started flowing perfectly.  They were using Office 2007 on the desktop I replaced. Other PC's in the office run Office 2013 or 2007.

ESET Endpoint anti virus is installed on the new desktop.

When he receives an email with an excel attachment and double clicks it to open it, Excel opens but no spreadsheet appears as if Excel was launched but no file was opened.  If he saves the file to disk, he can usually open it fine.

Also, on some spreadsheets, when he opens them, he receives the message "There was a problem sending a comand to the program".  I Googled that error and had him make this change which didn't resolve the issue.

1. Click the File tab, and then click Options.
2. Click Advanced, scroll down to the General section, and then clear the Ignore other applications that use Dynamic Data Exchange (DDE) check box in the General area.
3. Click OK.

Did you try to temporarily disable ESET? This all looks like its fault.

I had him right click the ESET icon and temporarily disable protection. he opened Outlook and Excel, but the problem persists.

Then maybe some Office components were corrupted / replaced with wrong versions. Try to repair Office installation. Or just reinstall the Office.

Hi performed the repair from Online but that didn't resolve either issue.
DDE is an ugly beast. It does sound like Office 2013 still sees remnants of Office 2007. Try doing a thorough uninstall to make sure the 2007 remnants get removed:

1) Uninstall 2013
2) Delete (or rename) the C:\Program Files\Microsoft Office 15 folder
3) Use ccleaner to cleanup the Registry. Be careful when using ccleaner! It can break other apps if you delete everything that it suggests.
4) Reinstall Office 2013

This is a new Pc where only Office 2013 was installed, not 2007. I don't see where an uninstall and reinstall makes any difference. We already performed a online repair.

Any other suggestions?
Sorry, I interpreted this comment: "They were using Office 2007 on the desktop I replaced" to mean that this was an upgrade.

Regardless, if this problem only happens with Excel, but other attachments work normally, then Office is definitely broken.

You are assuming that an online repair can repair all problems, which is a huge assumption.

Since you already tried an online repair, I only see 2 alternatives: 1) do a thorough uninstall and reinstall of Office, and 2) reinstall Windows.

there are also big differences in file types between 2007 and 2013 -- if they are licensed and mainly use 2007, then it might be prudent to install 2007 on the new system, and see if the flaw occurs.  Also need to ensure ESET and the Outlook add-on are Office 2013 compliant (or run Outlook in safe mode).

the patches for 2013 after SP1 has been applied are about 70+, i assume you have installed those too?

Also check the Trust Centre settings (Attachment Settings) for the user's Outlook, you can turn off some of the warnings, it should then allow the attachment to open.  You may also require to check Excel's same settings, especially for Trusted Docs (allow network files to be trusted).
