Excel 2010 Crashing on password protected spreadsheets
Posted on 2014-04-03
I have a client who's Excel has been crashing on him regularly. He is running Excel 2010 on a Windows 2008 R2 terminal server. I was able to narrow the issue down to opening password encrypted spreadsheets while a particular add-in was active. There are 10 other users who have not experienced this issue. The clients use LaserFiche document management software which has Outlook, Word, and Excel add-ins for saving documents into it's database.
What I found was that disabling two of the LaserFiche add-ins allow Excel to work correctly. There are separate add-ins for Excel 2010, 2007, and 2003. Disabling the 2003 and 2007 add-ins allows everything to work correctly. If they are enabled, normal spreadsheets work fine. Password protected spreadsheets will load Excel, prompt for a password, then after that is submitted, immediately shows "This program has stopping working".
Since the client is using 2010, I have no issue with leaving the other add-ins disabled (I don't know why they are enabled in the first place). The problem is that every time Excel is closed, they are enabled again. Does anyone know how to keep disabled add-ins disabled? I'm hesitant to completely remove them as I would have to do it for all users and I hate to open that can of worms since no one else is complaining.
Are there any other routes I should be taking to address this? I tried to reach out to LaserFiche support, but they hadn't heard of this issue.
