Language setting of Visual C# causes error

Question

Language setting of Visual C# causes error

Stan Huang 421

I opened my C# project and started it, it ran very well as my expect. Then, I stopped it and changed language setting from Chinese to "Same as Windows" or English. I reopened it and got error, as attached. How come?

Which version of VS are you using?
That's been happening for me on the current latest preview release - I'd put it down to it being a preview quirk, so hadn't worried about it so far.

Answer 1

Hi @Stan Huang ,

Thank you for reporting it in Microsoft Q&A.

From the screenshot, I suppose you are using the Visual Studio 2019. Have you tried to create a new C# project and check if the error occurs in specific project?

Please try to repair your Visual Studio by running your VS Installer > More > Repair.
After that, please open your Command Prompt and go to C:\Program Files (x86)\Microsoft Visual Studio\2019\[version]\Common7\IDE folder. Then, run the command: devenv /safemode to run your Visual Studio in safe mode. If your Visual Studio works fine in safe mode, the error may be caused by installed extensions. Please temporarily disable the extensions from Extensions > Manage Extensions > Installed > select and disable. Then, relaunch your Visual Studio as administrator to check if it works.

Sincerely,
Anna

I just download VS 2017 (vs_community__13132988.1488924318) and got the exactly the same result. It's strange.

Hi @Stan Huang , please have a try with the following workarounds:

Update your Visual Studio to the latest version.

Re-launch your Visual Studio and ensure that you have signed in your account on the upper right.

Close the Visual Studio instances and reopen your project.

In addition, have you tried to change the language setting from “Same as Windows” back to “Chinese”? Please check if the error disappears.

Hi, AnnaXiu,

I downloaded Visual Studio less than one week ago. So, it must be the lasted.
I can't re-launch it because it showed only the error message I attached at the last posting once I ran it.

Actually, I uninstalled it and re-installed more than once and got the same result. I think some bad setting was not removed even I uninstalled it. Maybe you need to teach me how to remove the whole Visual Studio package, including all its configuration and setting, not just the program itself. Then, I can reinstall it. It will at least run under Chinese mode.

Hi @Stan Huang , you could try to run the InstallCleanup.exe to uninstall your Visual Studio. (It will remove all installed instances of Visual Studio 2017 or Visual Studio 2019.)

Hi @Stan Huang , could you tell me the result you got? If you can’t uninstall Visual Studio cleanly, you could have a try with the following:

Manually delete any leftover install and cache folder you previously installed to
C:\Program Files (x86)\Microsoft Visual Studio
%programdata%\Microsoft\visualstudio\packages

Delete the setup registry key, which was set when you first installed:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\VisualStudio\Setup
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\Setup
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\Setup

I removed hotkeys and C:\Program Files (x86)\Microsoft Visual Studio
%programdata%\Microsoft\visualstudio\packages after un-installation, then I got the same result

Hi @Stan Huang , I suppose you can successfully install the Visual Studio. If the error occurs in launching your Visual Studio, please temporarily disable any anti-virus software on your computer before starting it.
Meanwhile, you can also try to repair your Visual Studio by running your Visual Studio Installer > More > Repair.

I disabled the anti-virus and re-installed it and then "More --> Repair" and then launched it, I still got the same result.

Is it possible you connect to my NB using TeamViewer to work on it?

Dear customer, please have a try with the following steps: open Windows Settings ( Windows + I ) > Go to Update & Security > Troubleshoot > Windows Update > Run the troubleshooter, which will help you check if there are some problems in your computer. If possible, please firstly activate your Windows.

By the way, the activity log is unavailable, can you upload it again?
