Hi,
New to this forum, have searched and not found anything in regards to my actual issue.
Problem,
When you install Office 2013 Home and Business onto Windows 8.1 either an upgrade to 8.1 or a fresh install, I've found the mail program in Control Panel won't open.
You can't call apon the program from RUN or CMD, you can't even call apon the Mail app from Program files\office 15\mlcfg.clp right click and select Open in Control Panel.
This issue has arisen with Windows 8.1.
scenario, New Dell OptiPlex 3020 & 9020, You Install Office 2013 Home & Business either OEM or the OEM Builder pack, before or after then run the Windows 8.1 upgrade from the Store, attempt to open the Mail app in Control Panel and the Mail app ceases to respond.
Yet, you are able to open the Mail app before the upgrade.
I just did a fresh install for a customer of Windows 8.1 OEM on an ACER laptop, tested with OEM media and the OEM Builders Install package, 32x & 64x installs and both failed to open the Mail app in Control Panel.
Actually the first install I performed didn't install the Mail app icon in Control Panel at all.
The only way I've found to rectify this issue is to run a full repair from Programs in Control Panel, which takes a while to run.
