RE: d3d12.dll error on Windows 8.1

[Kees Zeelenberg]

DirectX12 is not available on Windows 7 and 8; DirectX11 is the latest. See 
https://support.microsoft.com/en-us/topic/how-to-install-the-latest-version-of-directx-d1f5ffa5-dae2-246c-91b1-ee1e973ed8c2

The dependence on DirectX12 comes from Qt 6; see 
https://doc.qt.io/qt-6/qtquick-visualcanvas-scenegraph-renderer.html#rendering-via-the-qt-rendering-hardware-interface.
 This page also says that you may set the environment variable QSG_RHI_BACKEND 
to one of the values vulkan, metal, opengl, d3d11, d3d12. Since d3d11.dll is 
also a dependency of QtGui.dll, you might try whether setting  QSG_RHI_BACKEND 
to d3d11 works, although, since d3d12.dll is a direct dependency of QtGui.dll, 
I suspect it won’t; if not, you could try renaming a copy of d3d11.dll to 
d3d12.dll and add it to the LyX/bin directory.

 

Quite another possibility is upgrading to Windows 10; this used to be free when 
you have Windows 8.1, but I’m not sure whether this is still possible.

Onderwerp: d3d12.dll error on Windows 8.1

 

Good time of day.

I’ve just installed your program on Windows 8.1 on old desktop. We have few 
money in office to buy a newer one.

Then I saw an typical error about missing d3d12.dll in the system. Same problem 
with texstudio.

On Lyx site is written that the last version 2.4.2 is compatible with Windows 
7, Windows 8, 8.1 but seemingly it’s not.

Do you know what to do?

With best wishes, Taras

No, only in document settings, as in the attached example.

If the problem does only occur in the preview, the problem is somewhere
else. Again, check the temporary directory for all *.log files and post
them here.

Only with some kind of batch find/replace in the LyX file directly.

Best,
Jürgen

thanks for all the help so far, when I tried to change the fonts to Roman
or Arial both failed, they make many errors pop up the file doesn't compile
and the preview still isn't working as intended only David seems to work
for me, and I don't have "David CLM" in the dropdown options.

about the command you suggested ("\newfontfamily\englishfont{Some working
font}") do I just enter in the preamble of each file from now on? and what
font can I know for certain will work without trial and error? (there are
too many fonts to try) all these "debugging" techniques are completely new
to me so I'm really ignorant right now.

Thanks again for all the help,

Matan

(for some reason i didn't receive this reply so I copied it from the mail
archive)
I downloaded "David CLM" font like you suggested and installed it in
windows font folder, and then restarted lyx and checked the testing file I
send you, but it didn't solve the issue, am I supposed to change it in the
preferences as well and not just in the document settings? (following image)
[image: image.png]
I also tried this command you suggested but it didn't change anything as
well.
I might miss things and important info that would help me help you, when I
go over what's written in the "testing" file I sent the English is in
"Font: Default, Language: English" Hebrew text is in "Font: Default", and
the inside of the ERT is in "Font: Typewriter, LaTeX text, Language: LaTeX".

i even tried in a new LyX file just have the preview-ERT combination with
the same code and fonts like you suggested but the same old problem
persists, it compiles but doesn't render in the LyX file.

BTW is there some way to apply the fonts once for all the files i will
create and have created already, without the need to go file by file and
open the document settings for each?

Thanks again, I appreciate your support,

I mean as an English font, not default font.

You probably would need to install it first. It is available for free
on the Internet. Search for "David CLM otf".

Only in the files where you use PGF probably.

Try \newfontfamily\englishfont{Palatino} for instance. Any standard
serif font should do. As said, not needed if the Hebrew font is
comprehensive enough (such as David CLM).

It sounds, therefore, as if one could compile LyX 2.4.2 with Qt 5, and 
that would avoid this problem. Yes?

I don't have the font "David" installed, after changing it to "David
CLM" preview works and the file compiles.

With David, you might have to specify a font for English via

\newfontfamily\englishfont{Some working font}

as it seems to miss characters needed for the PGF graphic.

No, but I redirect this reply now back to lyx-users.

This shows errors:

! Missing $ inserted.
 
$
l.79}
 ^\text{complex number}

and

! Missing $ inserted.
 
$
l.80 \]

We'd need to see the document to make a definite judgment, but it looks
like you are using invalid stuff (maybe ^ in ERT?)

I've attached the LyX file here, I didn't use ^ in ERT but maybe something
else is wrong (btw wouldn't using ^ just cause the file to either not
render in the compiled output or not compile at all?)
