message "Failed to load C:\Program Files (x86)\SDL\SDL Trados Studio\Studio4\SolidFramework\SdAppSrv"

I get the message "Failed to load C:\Program Files (x86)\SDL\SDL Trados Studio\Studio4\SolidFramework\SdAppSrv" after uploading a pdf file in Trados 2015 and setting the languages. Is this problem related to a Windows 10 update? How can I solve it? Do I have to uninstall and reinstall Trados?
