I have MS Office 2010 running as an installed application on Xenapp 5 (Server 2008 R2). A number of users are unable to open any Office documents as they get an open-with dialog box instead. The users are connecting from IGEL thin clients to a published desktop.
This isn't affecting every user or the same users on different servers. I've checked file associations etc. both via the Default Programs Control Panel applet and in the HKEY_Classes_Root reg hive but everything looks ok.
I've hit a dead end with this one, any and all assistance appreciated.
