I have a user at my company who creates a PDF report from multiple excel sheets. She use's Acrobat DC's Combine Files' Thumbnail View to sort through sheets she want's to put in the final pdf. PROBLEM is this,Combine Files shows a couple of thumbnails for a few files, and then gets stuck when loading the rest. Acrobat itself doesn't freeze. All the excel files work properly and are not corrupted.Also all files can be combined to create one large pdf but that defeats the purpose of the user want's to do. User has Acrobat DC & Reader DC, Office 2010 (32bit), and Windows 7 Enterprise (64bit) - All which are up-to-date.
I've tried everything, disabling office & acrobat security settings, installing Office 2010 (64bit), Office 2013 (64bit), Downgrading to Acrobat XI Pro, upgrading to Windows 10 Enterprise (64bit). No matter what configuration or version of recent Acrobat, the thumbnails cannot be viewed properly. Is there there a setting I'm missing or is this a glitch with Acrobat?
