Due to defective MikTeX installation, which I have not been able to fix for several months now after several unsuccessful trials of de- and reinstallations, I migrated to TeXlive. My documents run again now, which is fine. However I was not able to implement a PS viewer like Yap! which is used for TeXstudio with MikTeX. The default setting after installing TeXlive and TeXstudio afterwards is that TeXstudio uses Irvanview as PS viewer because it is on my system. But Irvanview gives me errors that it cannot display the files. PDFs with Adobe or Sumatra are fine after compilation. So it is not a compilation problem. But most of the time I don't need to open the PDF, but just want a preview.
I tried to install Yap! by itself, but however, after setting the PS-path in TeXstudio configuration to this, this just shows me an empty window which is completely different in general from the window I know from MikTeX's Yap!, besides not showing/opening any content.
Sorry if this is a stupid question, but I haven't found an answer for this in my research. How do I set up an internal PS viewer in TeXstudio using TeXlive?
I try to clarify. I usually compile with xe- or lualatex. Now that I reinstalled TeXstudio after TeXlive I recognized that Irvanview opens instead of the preview and gives me error. The only path in TeXstudo that shows Irvanview is ps-path, so I thought there is a misconfiguration. Can you please tell me how to configurate these paths without getting unwanted programs and their errors? I can set the pdf-path there, but that is not a preview then anymore. Or do you all usually use pdf (adobe, sumatra, etc.) there? Maybe I am just not used to that.
