No, it has always been the same -- Windows 10. As always, I give instructions to my students how to set up arq on their computers, and all but one student did not have any problems with it. One student had problems installing it on his new PC and after being unable to do so, get it to work on his old PC. I am planning to try to get it installed on my old PC that has no apache jena on it to see what happens. I am using Fuseki as a way around at this point. This is very confusing indeed. Thank you for any idea that you may have to help me fix this. Regards, Neli.

Did you change your operating system since you used it last time? As it was working before, was it MacOS or Linux and now you're using Windows?
