I have Texmaker installed on my laptop and desktop, both 5.03 (I originally installed them at the same time) and while my desktop works fine my laptop's version refuses to compile a new pdf file or update the embedded viewer. I'm opening and editing the same files on each via google drive back up and sync, but not at the same time. When I originally installed it it was working fine but stopped without me changing anything (to my knowledge).
I have tried reinstalling TexMaker and I have looked through the configuration but, from old solutions it seems all right. I have attached images of my configure options.
Any help would be much appreciated!
