I recently installed MS Office 2013. It's all working fine so far apart from one thing – no compatibility with Mendeley. This is a big deal for me as I have thousands of references stored in Mendeley and several papers in need of review which also depend on Mendeley for reference management.
Since apparently it will be a month or so until Mendeley release version 1.9 which should bring support for Word 2013:
1) How do I get back my installation of Office 2010?
2) Can I restore just Word 2010 and keep Outlook, Excel, etc as 2013?
