HI, I wonder if you could possibly provide some guidance and support?   I have a full registered version of Nitro Pro Nitro Productivity Suite Includes Nitro Pro for desktop PDF productivity and Nitro Sign for unlimited eSignatures Following a recent Windows10 update, (Why do they do it!!!!!!!) which appears to have by default edited the Registry file, it now ensures that whenever I use the application I have a script file running in a loop which cannot be defeated.
