Hi. I try to run/debug C/C++ project and I keep getting this error message.
I tried to repair VS 2022 from the installer with no success.
I tried to remove it completely using InstallCleanup.exe and installing it back with no success.
https://learn.microsoft.com/en-US/visualstudio/install/uninstall-visual-studio?view=vs-2022#remove
This is the output the Administrator Command Prompt:

What else can I do to solve it?
Thanks.

Hello, does it happen if you create other types of projects? Or does it only happen in C/C++ project?
If you have anti-virus software installed on your computer, please temporarily disable them and run again. And check if the antivirus is causing the error or not.
Hello, I installed Python to check what happens and the Python project runs perfectly and debugs perfectly.
After that, tried again to run/debug C++ project and got the same error.
Is there no way to solve this issue?
Sorry for my delay reply!
Did you install any third-party extensions? Please temporarily disable them under Extensions > Manage Extensions > Installed.
Then, close all running VS instances, launch your Visual Studio Installer and uncheck the workload "Desktop development with C++".
Rebooting your computer and re-check the workload "Desktop development with C++" to create a new C++ project again.

No, please click on "Modify" after launching your VS installer.
OK. I did all the steps. same error.
About a month ago I installed DPC++ workspace to learn about parallelism programming, I couldn't use it at first and I didn't have time to dive in and check why, but I did manage to run a project in C++, so I don't know if it's related.
I uninstalled VS 2022, I uninstalled Visual Studio Installer and installed them again and still getting the same error.
Do you have credentials of Administrator login. also to mess with windows registry?
Yes, I do.
Hi @AsafY , One solution is to delete few registry key value. But take registry back-up before you work with regedit. This activity may solve or spoil the registry. If you are ready to take risk then do regedit.
Note: sometimes windows registry get corrupted so installation of few packages fail or does not work properly.
Ok, I will do it. which registry key do I need to change?
Is there no way to solve this issue?

Is there no way to solve this issue?
Currently, the latest version of VS2022 is version 17.3.2. Could you update it to the latest version and check again?
Meanwhile, Can you temporarily uninstall the "DPC++ workspace"?
I completely removed the DPC++ workspace and update VS to 17.3.2.
Still getting the same error.
What else I can do?
Please close all running Visual Studio instances and clean the following folders (Please first backup these folders):
C:\Program Files (x86)\Common Files\Microsoft Shared\VS7Debug
C:\Program Files\Common Files\microsoft shared\VS7Debug
Then, open your Visual Studio Installer and click on More > Repair the Visual Studio.
My comment is just a ray of hope. Search for related keywords as in error into windows registry. Delete them manually. Then try re-install VS 2022. Highlight is Repeated Install/Uninstall means Visual Studio Installer is finding some keys/values (not sure if encrypted) that is already present in registry. Please make sure all folders backup as suggested by @Anna Xiu-MSFT Also data backup. Hope you issue get addressed and resolved soon.
Still getting the same error.
I have searched the keywords: Visual Studio in Registry Editor, it give me the result:
Computer\HKEY_CLASSES_ROOT\AppID{534E4CF4-3249-4842-8D65-A9BEAE0BBEAC}
there is a value named (Defualt) of type REG_SZ with the data: Visual Studio Just-In-Time Debugger (Internal)
Can I delete this value?
@AsafY Before I could reply you with delete or do not delete. I am getting a question. do you know steps for restoring of windows registry?
Regarding my knowledge I mess with registry as a beginner. Did hands-on to my own computer. But during this task I do not require the step of restoration registry. So I have limited knowledge. please feel free comment.
No. I don't know the steps.
Why there is no way to solve this issue?
It's my personal computer.
It means, working at own risks. Try to find all key/value pair of C++/Visual C++ and delete them manually. Then try to install/re-install/repair.
good luck.
Note: If it works, good. else sorry and i give-up as of now. As I get very limited time to login in here and look into threads that I pursue.

I am experiencing a similar problem. The problem is I have reinstalled my visual studio a few times, and i am quite certain that is an operating system issue. Presently, the microsoft store app does not work, with the relevant dll libraries sighted as issues. Which means that the .Net SDK/library pack installed by the system is broken. Can anyone suggest a fix rather than an OS reinstall which might be necessary?
NB: saying most likely VS is installed as best as it can possibly be installed and no reinstall would ever ever help.
