This morning I was successfully editing documents online via the Alfresco Explorer and Office 2007.
At about 1pm I decided I'd upgrade to Office 2010 and as soon as I did that the Online Editing stopped working! Basically I click edit online it now asks me to download the document, I download, edit, save the document click finish editing in Alfresco Explorer and the next time I view the document none of the changes are there!
Anyone ran into something similar, perhaps a security setting or something?
If anyone runs into the same issue, it's because I was using Internet Explorer 64bit and Office 2010 32bit. As soon as I switched over the IE9 32bit the thing started working again.
