can't start Studio 2015, Sdl.TranslationStudio.AlignmentEditor.IAlignmentEditorService could not be started

Dear all,

I have installed Trados Studio 2015 on 10 different office computers.

After installation everything was fine till today. 9 computers are working without problems, but one can't start Studio and gives error - Sdl.TranslationStudio.AlignmentEditor.IAlignmentEditorService could not be started

What is already done- 1) have read all related articles, 2) repaired and reinstalled Studio, 3) repaired all components c:\ProgramData\Package Cache\SDL\Dependencies\, 4) removed all mentioned components and then repaired and reinstalled Studio- and still no luck :(

What else can be done?

Thanks in advance!
