Attempting to display LaTeX in Anki causes error? - windows

I'm trying to enable LaTeX for Anki flashcards. I have MikTex installed and, upon attempting to view cards with LaTex formatting, I get the following error:
Définissez Problème à l’exécution de latex.

I've already disabled automatic package installation/prompting of the user to install unknown packages in MikTex, to no avail.
What can I do to fix this so that Anki displays LaTeX cards?

I was experiencing similar problems and none of the in-depth ansers seemed to help me , but I just stumbled upon a solution that works for me.
As long as I only use \( to begin LaTeX Code and \) to end it, everything works well on my two Windows computers, as well as my Android device.
example:
\(\sum_{k = 1}^{\infty}\frac{1}{k}\)
instead of
\begin{math}\sum_{k = 1}^{\infty}\frac{1}{k}\end{math}
Hope this helps other noobs as well.

Fixed the problem by following the tutorial at
http://www.eighthourlunch.com/content/anki-setting-latex-windows-7
One issue which was unclear in the tutorial was installation of the xml/sgml typesetting package. It is called passivetex and can be viewed at https://miktex.org/packages/passivetex
Use the filter menu in the packages tab of the miktex console to explicitly search for passivetex . Once installed, I updated the file name database (Tasks -> Update filename database) and Anki started working correctly.

Multiple problems installing TeX Live 2021 on Windows 10

I have a Windows 10 laptop where no TeX distribution was ever installed before (double-checked for config directories, files, and environment variables).
Wanting to install TeX Live 2021, I followed the full installation guide and also read the Windows-specific warnings. I've now tried several times, following different installation procedures - cleaning up everything (deleting base & user directories, environment variables, etc) before each time - but still don't manage to get a working installation. Before I report a bug at tex-live#tug, I wanted to ask for advice here, in case I'm doing something wrong. Here is what I did, step by step, and the problems I encountered in the process.
1. First I tried running the recommended online installer install-tl-windows.exe. It never got past the screen that tries to contact or load from a repository, even after a 30-min wait. Tried a dozen times, choosing different mirrors nearby and far away. No luck.
2. Then I downloaded and unpacked the install-tl.zip and run install-tl-windows.bat therein. This time the main installation window appeared. I left all default paths and environment variables (note that I do have write access to C:); in the selection scheme I unselected all languages except US & UK English, unselected XeTeX, LuaTeX, ConTeXt; also unselected TeXworks (I use Emacs), and clicked Install. After one to three hours (depending on the mirror I chose), the installation was complete.
I tried compiling a minimal latex document (see below), and got an error similar to the one in this old question:
I can't find the format file `pdflatex.fmt'
Following the advice in the answers to that question and similar questions elsewhere online such as this, I tried running texhash and fmtutil-sys --all. The latter gave the error
no appropriate script or programme found fmtutil.
for which there are also many posts online.
2a. Not understanding what the problem could be, I re-tried with all possible combinations of the following three options: (a) choosing different mirrors; (b) leaving the full selection of packages (ie without unselecting some languages, LuaTeX etc); (c) redoing the procedure by choosing "Run as Administrator". No luck.
3. At this point I tried downloading the ISO file with the full installation. Mounted the image and run install-tl-windows.bat (as normal user, as recommended; I repeat that I do have write access to C:). Everything proceeded as in step 2. above. At the end of the installation I tried running pdflatex on the minimal latex document. New error this time:
This is pdfTeX, Version 3.141592653-2.6-1.40.22 (TeX Live 2021/W32TeX) (preloaded format=pdflatex)

! LaTeX Error: File `article.cls' not found.
Very strange. A file search revealed that article.cls is in the TeXLive file system; but kpathsea did not see it indeed.
4. At this point I opened the TeX Live Shell from the Start Menu; selected a CTAN mirror; updated the TL Manager which was not up to date; updated all packages; run Regenerate filename database; and run Regenerate formats. With the latter I got this error:
tex live shell:

I tried to continue anyway with Regenerate fontmaps, and then tried again pdflatex on the minimal document. New error:

(Fatal format file error; I'm stymied)
5. I tried again steps 3. and 4., but with "Run as Administrator". Same errors.
OK at this point I give up and really don't know what to do. Am I doing something wrong? For the moment I have to concur with this post: installation of TeX Live 2021 is an utter failure.
Here is the minimal latex file I used for testing (copy & paste):
\documentclass{article}
\begin{document}
test
\section{Section}
test
\end{document}
Found, that the download is not working because the system path to "cmd.exe" is not found. Therefore: open a cmd window and add the system path prior to starting the .bat file (set PATH=%PATH%;C:\Windows\system32)

Error in publishing to RPubs from Rstudio

I installed the latest version of RStudio (RStudio 1.1.423 - Windows Vista / 7/8/10).
I'm trying to publish to RPubs, but in Global Options does not appear the option for Rpubs.
When I request Publish Document, the following error appears: Error occurred while executing method.
Rprofile:
I entered the command: options (rpubs.upload.method = "internal") at line 25 of Rprofile, but it did not resolve.
The solution is provided by a careful rereading of http://rstudio-pubs-static.s3.amazonaws.com/25030_8e9c9ffc3b3c423d9381d81543423502.html
"Put in options(rpubs.upload.method = “internal”) and no other text at all". Meaning that this line of code is the only code present in the .Rprofile file.
Previously I had been adding the line to a copy of the rest of the Rprofile text. The unnecessary code was the culprit.
I had the same error before. Turns out it was due to having an accent mark in a folder name from my directory (í). I just modified that one folder name and it worked fine.

Rmarkdown knit error: Fault/access violation in generated code

I've got a particular bug in my environment such that I cannot consistently knit Rmarkdown files to HTML, Word documents, or PDFs. The ability to knit varies across by file type.
HTML - Sometimes it knits
Word document - Sometimes it knits
PDF - Never knits. Always throws the same error
The error is:
Segmentation fault/access violation in generated code
Error: pandoc document conversion failed with error 1
Up until a week ago, I was able to knit to all three file types in the same environment so this is a relatively recent bug. The high-level specs of my environment are:
OS: Windows 10
R: 3.4.3
RStudio: 1.1.419
knitr: 1.19
rmarkdown: 1.8
pandoc: 1.19.2.1
MiKTeX : 2.9
As an example of the inconsistency in the ability to knit, I crated a new .Rmd file in RStudio which creates the familiar standard template of summary(cars) and plot(pressure) etc. I didn't change anything about it. I was able to knit it successfully to HTML once, Word .docx once, and then I tried to knit to PDF and got the error above. I then went back and attempted to knit to both HTML and Word and received the error even though nothing changed from the original knit. This is just an example of the type of behavior. Different documents behave differently.
To troubleshoot, I've reinstalled R and RStudio (I believe pandoc comes up with the RStudio install so I've effectively reinstalled pandoc too). The reinstallation did not help. I've tried clearing the Knitr Cache. That didn't work either. I've browsed SO and the internet and found a few similar errors related to the Glasgow-Haskell compiler, but I have no idea what that is and if it's the source of the issue.
Here is an example of the .Rmd file that throws the error:
---
title: "Untitled"
author: "Vypa"
date: "February 8, 2018"
output:
html_document: default
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## R Markdown
This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
```{r cars}
summary(cars)
```
## Including Plots
You can also embed plots, for example:
```{r pressure, echo=FALSE}
plot(pressure)
```
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
And here is the full console error:
Segmentation fault/access violation in generated code
Error: pandoc document conversion failed with error 1
In addition: Warning message:

Any help or thoughts would be appreciated.
Encountered the same problem after a recent install of R & RStudio on Win10. Pandoc problem showed up on edit and knitr of previously err free .rmd file.
Resolved after installing latest preview ver of RStudio at
https://www.rstudio.com/products/rstudio/download/preview/
Updating pandoc fixed this for me.

Thanks #EuGENE. Adding here as an answer for clarity.

F# Microsoft.ParallelArrays not defined

So I downloaded and installed Microsoft Accelerator v2 to use ParallelArrays. I have referenced it in my project but when I try and execute the code from the module in a script file I get:
"The namespace 'ParallelArrays' is not defined
I have followed the instructions on this post:
Microsoft Accelerator library with Visual Studio F#
I've added a reference to the managed version "Microsoft.Accelerator.dll" to my F# project and then added the native "Accelerator.dll" as an item in my solution and set it's 'Copy To Output Directory' to Copy Always.
Still getting the FSI error and inline error in my script file on the '#load ...' line, however the solution builds fine, and no error in the module file.
Any ideas on what I'm missing? I'm sure it's something stupid.
Thanks,
Justin
UPDATE
I tried mydogisbox's advice, which got rid of the error above, but now when I run the code in the .fsx file I get this error instead:
--> Referenced 'F:\Work\GitHub\qf-sharp\qf-sharp\bin\Debug\Microsoft.Accelerator.dll' (file may be locked by F# Interactive process)
[Loading F:\Work\GitHub\qf-sharp\qf-sharp\MonteCarloGPU.fs]
error FS0192: internal error: F:\Work\GitHub\qf-sharp\qf-sharp\Accelerator.dll: bad cli header, rva 0
UPDATE 2
So the bad header error has dissapeared, but now I get this instead:
Microsoft.ParallelArrays.AcceleratorException: Failure to create a DirectX 9 device.

Stopped due to error
I found this thread on MSDN however the answers proposed as fixes on that thread barely even relate to the question.
http://social.msdn.microsoft.com/Forums/vstudio/en-US/98600646-0345-4f62-a6c5-f03ac9c77179/ms-accelerator?forum=csharpgeneral
My Direct X version is 11, and I imagine that will suffice, however I tried installing DX9 however, it tells me that a newer version is detected therefore cant install.
There are special directives for referencing dlls from fsi. The #load directive loads the .fs file only. You need to use the #r directive to reference the file. You can either use the full path of the file or you can use #I to include the path to the file. More details here. Keep in mind that fsi is completely independent of your project, so all references in your project must be duplicated in fsi for it to access the same types.

Windows 8 driver install and catalog/signature validation

I can't get windows 8 (release preview) to accept either the inf2cat or makecat approach described as solutions to the question at
What changed in the driver signature requirements for Windows 8?
unless I disable validation.
I am not signing these with any certificates at this point, just trying to get past the errors preventing the drivers from installing at all.
Windows 8 gives me a very nondescript error:
"A problem was encountered while attempting to add the driver to the store."
Looking in the event logs, there is nothing of use; only an informational entry from "Windows Error Reporting" indicating a PnPdriverimporterror.
When i use my original files with the cab files that don't match the inf, I get the error everyone else is listing:
The hash for the file is not present in the specified catalog file.
I have one .inf file that i need to generate a .cat for.
Perhaps I am doing something wrong. Ideas??
INF2CAT Approach

These same files, w/ the cat from either approach install just fine in Windows 7.
I think this problem is to do with "windows driver signing enforcement". You can resolve this by disabling this option. Go through with below link:
http://tivadj-tech.blogspot.in/2012/09/certificate-check-error-when-installing.html
I just tested this on Windows 10 and 8 PRO now, to get this right, follow these steps:
1) From your Start menu, locate your DDK's "x64 Checked Build Environment" i.e. the custom DOS build screen. Right-click, run-as administrator...
2) Compile your source with the Build tools etc.
3) Go into your compiled code, and then create your test-certificate (you don't need to purchase one just yet, use your self-signed one created with the line below):
makecert -r -pe -ss PrivateCertStore -n CN=newhex.com(Test) NewhexTest.cer
The above means your certificate is called "newhex.com(Test)" and the generated file is "NewhexTest.cer"
4) Create / Edit your .CDF file which contains items about what your CAT file's contents.
5) Create your CAT file by executing:
makecat -v MyCDF.CDF
This should generate an un-signed CAT file that includes all files specified by your CDF.
6) Sign your CAT file as follows:
Signtool sign /v /s PrivateCertStore /n newhex.com(test) /t http://timestamp.verisign.com/scripts/timestamp.dll MyDriverWhatever.cat
This should result in a CAT file that is signed, but don't just install it, because your Windows can't trust Newhex's cert since it's not in the keystore, to fix this do:
7) Add your certificate to your private Key Store, remember this step MUST be done by an administrators access, otherwise you will get an error about (Keystore not found etc):
certmgr.exe -add NewhexTest.cer -s -r localMachine root
This should add into your keystore, Once done, you can then:
8) Go into your device manager, and add your new driver, you would get a warning but will be accepted and installed without the need to reboot with a forced (Don't check cert type account).
I tried this already and it works on Windows 10 and Windows 8 pro versions.
Kind Regards
Heider Sati
You are supposed to use inf2cat, not makecat, because you have an INF file.
You should work on addressing those warnings from inf2cat by fixing your INF file. Here is my INF file that uses usbser.sys and doesn't cause any warnings: https://gist.github.com/3647208
I was able to fix my INF file thanks to the advice from chinzei in the first post of this thread: http://www.microchip.com/forums/m488342-print.aspx
If you continue to have trouble, please edit your question to include the source of your INF file, or at least a link to the source.
I encounter the same problem and was able to install my driver with a TEST certificate using the instructions provided here:
