Sdl.TranslationStudio.AlignmentEditor.IAlignmentEditorService

Question

When I try to open SDL Trados Studio 2017 it gives me this message: "Sdl.TranslationStudio.AlignmentEditor.IAlignmentEditorService" and "Cannot validate SDL plug-in:Sdl.FileTypeSupport.Filters.Xliff.XliffComponentBuilder,Sdl.FileTypeSupport.Filters.Xliff, Version= 9.1.0.0, Culture= neutral, PublickeyToken= c28cdb26c445c888 : C:\Program Files (x86)\SDL\SDL Trados Studio \ Studio 5\ Sdl.FileTypeSupport.Filters.Xliff.dll
Can someone help me? What should I do?
Thank you in advance

Hello Federica Cocuccioni , 
 
It sounds like your AntiVirus scanner has identified the Java resource.dll file as being harmful (wrongly) to the system and has deleted it. 
 
You will need to add your Studio folder to your AV so called 'whitelist' and run a Studio repair.
