Hello everyone, I am trying to install on my company pc the Modern Fortran extension but if I try to do so I end up with the following error: " [“Invalid: Corrupt ZIP: end of central directory record signature not found”," at G.downloadExtension (vscode-file://vscode-app/c:/Software/Microsoft%20VS%20Code/resources/app/out/vs/code/electron-browser/sharedProcess/sharedProcessMain.js:88:195231)“,” at async G.doRun (vscode-file://vscode-app/c:/Software/Microsoft%20VS%20Code/resources/app/out/vs/code/electron-browser/sharedProcess/sharedProcessMain.js:88:194173)"] " Since this might be due to the firewalls in place in the pc (although other extensions are installed without a problem), I tried to install it manually. I downloaded the "fortran-lang.linter-gfortran-3.2.0 " file and then I installed it from VSIX as instructed by VS code. However, I find the same error. Does anyone have any suggestion or explaination on why it is doing so? Thanks a lot, Giulio ---

what version of VS Code are you using? It sounds like you need to update VS Code, you need version 1.63.0+. Unfortunately, VS Code does not offer an elegant way to display version incompatibility, so it ends up printing cryptic errors. ---

I have version 1.72.0, which i think is the latest one. ---

Can you try and install cpptools [C++ programming with Visual Studio Code](https://code.visualstudio.com/docs/languages/cpp) and see if that is possible ---

I tried directly from VS code and gave me the same error. Then, I did it manually and it was fine, so now i have c++. ---

So it is probably your security options. Try and install the Modern Fortran extension now the same way from a local vsix. I suspect it was failing before because it was unable to fetch the C++ extension which we depend on for debugging. ---

Yes indeed now i was able to install Modern Fortran. However now the c++ extension gives the following two errors: _Missing binary at … .vscode\extensions\ms-vscode.cpptools-1.12.4\bin\cpptools.exe_ It says that it is not possible to launch the server, therefore the intellisense functionalities are disabilitated. _The C++ extension installed does not correspond to the system_ (I am translating so sorry if it is not clear) In any case i tried to move the path to which extensions are installed since the problem migth be running some executables, and to do so in this computer without issues i need to have it in a particular folder. I tried to use the following command: > code --extensions-dir C:\Software\VS\_extension But what it did was to open a new vs code window and create a misterious _extension_ file. If the i try to install extension it does not follow the directory written above. ---

You don’t need `cpptools.exe` to use the Modern Fortran extension, you only need some of its functionality when you are debugging. At any rate, maybe the following will help resolve your issue. The cpptools does a bunch of stuff online so that could be why it’s failing. I don’t think it lack of permissions and cpptools.exe should be present in an offline installation, so I would suggest you reinstall: - Uninstall Modern Fortran and cpptools. - Go into the directory where extensions are installed, that would be the thing you quoted above `… .vscode\extensions` - Delete any residual folders by the name `fortran-lang.linter-gfortran...` and `ms-vscode.cpptools...` - Download a fresh copy from the Marketplace for your OS for [cpptools](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools), see `Version History`. This should come with `cpptools.exe` preinstalled. You can check yourself after the download by looking into the vsix file, it’s just a compressed folder. - Download a fresh copy from the Marketplace for your OS for [Modern Fortran](https://marketplace.visualstudio.com/items?itemName=fortran-lang.linter-gfortran), see `Version History` If that fails might need to speak with your IT department to help you resolve this. ---

Ok thank you very much! Just one last thing. Since i also need to install fortls is there a way to bypass the pip installation? I tried doing the > pip install fortls command but i think the security is blocking it. I tried to download the _forls.tar.gz_ file but from there the instructions i found on the internet are not very clear. If you have any solution to this problem it would be very appreciated. Thank you in any case for your availability!! ---

You can do a few things: - Clone the github repo [GitHub - gnikit/fortls: fortls - Fortran Language Server](https://github.com/gnikit/fortls.git) and `pip instal -e .` from within the cloned repo - Download the source or built distributions [fortls · PyPI](https://pypi.org/project/fortls/#files) and install that with pip You will have to disable autoupdating since it will interfere with your firewall settings. For more please read the [Configuration options - fortls](https://gnikit.github.io/fortls/options.html) documentation. ---

Thank you! I was able to install fortls however vs code deosn’t seem to aknowledge it. I used the command > “fortran.fortls.path”: “c:/software/winpython/wpy64-3850/python-3.8.5.amd64/lib/site-packages” where i got the path by using `pip show fortls`, which gave back: > Name: fortls > Version: 2.13.0 > Summary: fortls - Fortran Language Server > Home-page: [https://gnikit.github.io/fortls](https://gnikit.github.io/fortls) > Author: Giannis Nikiteas > Author-email: [giannis.nikiteas@gmail.com](mailto:giannis.nikiteas@gmail.com) > License: MIT > Location: c:\software\winpython\wpy64-3850\python-3.8.5.amd64\lib\site-packages > Requires: json5, packaging > Required-by: Do you know why is this the case?

Unfortunately `pip show` will show you the installation location of the Python library not where the binary i.e. `fortls` is installed. In a command prompt you can type ```nohighlight where fortls ``` or in a Shell terminal ```nohighlight which fortls ``` and that will give you the path you need to use. In general, most times you can make a safe bet that that binaries are installed close to where the python module is installed in a folder called `bin`. So if you start snooping around `c:\software\winpython\wpy64-3850\python-3.8.5.amd64\` (maybe some directories up) you will find it). ---

Ok i did so! Now i have the following error: > Error launching fortls: Please check that all selected options are supported by your language server version. What could it be? ---

There should be a log message in the Output\>Modern Fortran channel attached to that. If you haven’t input any custom settings I would guess that the location shows py `pip show fortls` needs to be appended to your `PYTHONPATH` variable. That’s not exclusive to `fortls` any Python program that you try to run and the lib/ location is not part of your PYTHONPATH will fail because it won’t be able to resolve the relative imports of the package. ---
