[Tex/LaTex] Lyx not opening, windows 10

lyxwindows

Im having a strange problem. I have used lyx always and last time I used it was a few days ago.

Today my computer for strange reasons starting saying it was completely full (0 byte free!). Opened lyx to test a math equation layout, couldnt save document, couldnt display pdf. I thought it might be related to the disk space issue, so I restarted my computer, and now I had 11 GB free, as I should have (strange…).

Lyx now wouldnt open at all! No errors, just nothing. Ive tried to reinstall, same problem. Also if I reinstall to a different folder.

Im completely at a loss here, and cannot find similar problems and solutions out there. Did anyone try something similar? Im desparate since I have several papers and reports due this week!

Edit: more information: I'm using the newest LyX 2.1.4 and have Miktex 2.9 installed. I have TeXWorks installed as well, and it works and compiles, so its not a Miktex issue.

Seems to work again now. I installed LyX directly under C:\ instead of in Program Files , or in Program Files (x86), as it had originally been.

I don't know why this works or why the other one didn't since I have used it for years in that location.

Anyway, working now. Hope someone else benefits from this.

After testing the possibilities of adjusting LyX's behaviour using a "portable" approach as given in the other answer, in this case the solution was to simply add a fresh username composed of simple characters.

NOTE a number of users may arrive here who have either accented names or be composed UTF-8 characters or simply have a two-part name with a space. In such cases it is best to consider adding a new user to the system with a single plain ascii moniker.

e.g. c:\users\me\

IF you have already installed TeX and LyX you have likely encountered the issue of LyX complaining it cant find the TeX classes. So as a minimum uninstall LyX for that problem account.

Now using the new account BEFORE you do a fresh LyX install, first check that your TeX is correctly configured. On windows you need to confirm that the two following commands agree EXACTLY.

So to test all is well check that there is only one pdfLaTeX and that it is included in the path variable so from a command prompt run

>  where /r \ pdfLaTeX
>  where $path:pdflatex

both should agree it will of course vary for each user HOWEVER it should be one IDENTICAL entry for both commands

e.g. c:\ ..tex.. \ .. \some\bin\pdflatex.exe

Using the fresh account next check if installing LyX clears the problem. If you still encounter issues with the underlying TeX (MiKTeX or Tex Live) then you may need to consider re-installing one of those again. But again ensure you pass the where test before starting the new LyX.

When you make significant changes to the underlying programs especially MiKTeX updates, you may need to frequently use the "Reconfigure" option within LyX.

An associated problem can be the choice of PDF viewer since LyX uses background processes such as DDE or Pipes to control the pdf viewing. You may wish to check out alternatives.
