I already searched online for a Solution for the Problem also regarding the shown ntdll.dll in the Log and tried several approaches

- i tired a repair install (this also crashes)

- i tried uninstall and reinstall it

- i tried uninstall it with the "Adobe Reader and Acrobat Reader Toll" and then reinstalling it

- i diabled "protected mode" through the registry

- i searched for any third party plugins

- i cleared all the cache data in Program Files/Programs (x86) and the AppData Folder

nothing helped so far. Hope Somebody of you guys can help me.

best regards
