I'm running Office 365 and Windows 7 Pro. I have Avast antivirus up to date, and did a full scan recently.
Both Excel and Word are hanging when I try to open a document. If I launch the program directly (without double clicking on a document) the splash screen/start page open fine, but when I try to open a document it crashes.
Excel started hanging first. It worked fine in safe mode (including opening documents), so I disabled the AcrobatPDFMaker Office COM addin addin. That worked for a couple weeks, but now it is hanging again. ( I have the AnalysisToolPak and Solver Add-ins as well).
Word has also started to hang, initially in a similar manner - i.e., it will open but hang when trying to open documents, but works fine in safe mode. All addins are disabled.
I tried repairing the installation, but I got an error code when I did so, so I uninstalled it using the Fixit Tool and reinstalled.
Now not only does work hang when trying to open a document, if I click on "options" to see the addins, it hangs there as well. Safe mode is still fine.
I'm at a loss for what else to try. Nothing in the Event Viewer seems helpful.
