Hi,

the error is caused by the Add-In "PDFThumbnailAddon" please deactivate this addon by removing it rom the Citavi Add-Ons folder (C:\Program Files (x86)\Citavi 6\AddOns).

Best regards

Sebastian

Thanks a lot. It works. I uninstalled 6.8 and re-installed 6.7 yesterday, and it worked without any problem. So I wonder if there are something unexpected in the new version.

Hi

This is a third party add-on, we've notified its developer that it might not work with Citavi 6.8.

Best regards

Sebastian
