math preview works only with workaround

[Zaby1990]

Hello, I want to use the math preview but I have some problems with that and I didn't find my way in any issue. At first my system parameters: Win10x64, Sublime Version 3.2.2, Build 3211 x64, Texlive2020

If want to see the math preview, I got the error: ERROR: Failed to convert pdf to png to preview.

The System Check says all packages are availabe:

I can solve this problem the following way:

1. Installing Ghostscript 9.52 for Windows (64 bit) from https://www.ghostscript.com/download/gsdnld.html
2. Copy the file C:\Program Files\gs\gs9.52\bin\gswin64c.exe
3. Go to C:\texlive\2020\tlpkg\tlgs\bin
4. Rename gswin32c.exe to gswin32c_old.exe (or everything else)
5. Paste gswin64c.exe and rename to gswin32c.exe --> math preview works fine

BUT

after I do this little workaround the Latex Package epstopdf don't work anymore and I can't include eps-grafics to my Latex file

So is there another way to make the math preview work without substituting the gswin32c.exe?

I am very grateful for your help.

The much simpler thing to do is just:

1. Install Ghostscript and ensure it's added to your PATH variable
2. Restart SublimeText (to ensure it has an updated environment)

We only use the TeXLive Ghostscript as a fallback.

Hi ibacher, thanks for your answer. I wish it would be that simple. Like you can see in the given path in the system check, I already have added the GS Path my PATH variable. I also checked, that the path of the seperately installed ghostscript comes first.

Do I have to install the 32bit Version of Ghostscript or do I have to tell sublime, that it have to use GSx64?

Edit: I got another idea because of your answer: I deleted the texlixe-GS-path from my PATH variable so sublime cannot see the wrong GS.exe. This solves the problem.

Thank you for your help.

The updated solution of @Zaby1990 on May 7, 2020, did indeed do the trick. I've struggled quite a while with this issue. However I didn't notice that there were two entries for GhostScript in the PATH variable.

For future reference:

1. Have GhostScript installed independently on your system
2. Add C:\Program Files\gs\gs9.53.3\bin to your PATH variable (without the \bin it won't work and the naming will depend on the version of GhostScript you installed).
3. Remove C:\texlive\2020\tlpkg\tlgs\bin from you PATH variable
4. Restart Sublime and voila
