I just did a fresh install of Lyx 18.104.22.168 on Windows 7.
I have got a file called 'introductions-handouts.lyx' and when I click on 'view' it fortunately defaults to opening a pdf in my default pdf reader, Foxit reader. However when I click 'update' I get the following in the error log:
! I can't write on file `introductions-handouts.pdf'.
Please type another file name for output
! Emergency stop.
<to be read again>
I was pretty surprised when searching that more people have not had this problem. What should I do?
I don't think that closing the pdf file every time I want to update is a solution. When I am making fine typographical changes and update several times in a minute it would get very tiresome.
