When using Adobe Professional 9 with Windows Office 2010 we experienced error messages requiring that we reboot our computer and start again. This "fix" did not always work. 
My firm has since switched to Windows Office 2013. Do you know if this issue has been addressed in the upgrade to 2013?
Neither of these versions of Office is compatible with Acrobat 9, and there aren't going to be any more updates to it as it's past its end of support: Web browsers and PDFMaker applications compatible with Acrobat and Reader
Thank you try67. I looked at the support grid you included and it didn't make sense to me (not a techy). Is that a newer version of Acrobat Professional that works with Office 2013?
Yes, Acrobat XI (11.0.1 or higher) or Acrobat DC. Adobe only sells the latter currently.
