Edit: After wait too long, I have resorted to do a clean install of Windows 7.
It solves everything.
I believe the cause is : some Windows files, or some service are disabled, by me or virus.
Now, I can no longer test any solution so I accept the existing useful one.
Original Question
My Visual Studio 2017 can run & compile C++ code, but :-
(main problem) can't install any Extension (double click .vsix yield nothing)
double click .sln will popup "Choose Application" that shows no choice. (but "Open with..." works OK)
This issue happens only to my computer in workplace.
It had worked OK before I cleaned up my system.
I tried :-
install, uninstall and repair Visual Studio 2017 several times.
https://github.com/Microsoft/VisualStudioUninstaller
%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe -full then reinstall (can remove "(2)", but not other symptom)
update to the latest version 15.9.17
(Thank comment from Jeaninez - MSFT) Make sure my .sln start with this at the first line:-
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 15
I believe the issue is related to Microsoft Visual Studio Version Selector.
This symptom might come after I uninstall VS2019.
My system might be broken?
Perhaps, the cause may be somethings very deep in OS. I am considering reinstall Windows 7.
Reference:
Why I think it is Version-Selector-related : Can't install the extension on Visual Studio 2017 after installing Visual Studio 2019
Similar question (2014) : How do I add versions to “Visual Studio Version Selector”, my list is empty (repair not help)

To install extensions, try to find VSIXInstaller.exe on your disk. Normally it is installed here:
c:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VSIXInstaller.exe
I have been using Vs 2017 for several months on dev machine. This fine morning says setup incomplete. Am I missing something?
In this case you need to go to Control Panel => Programs and Features and choose Visual Studio and update it.
VS 2017 (15.6.6) was fine for me on Friday 6/1/18 on Windows 10, but same issue as OP today after a restart.
As suggested by the dialog and Retired Ninja, I ran the Visual Studio Installer (to 15.7.3 after updating VS Installer) and that fixed it.
Note that the 15.7.3 update was a 7.73 GB download. Your download size may vary.
This has happened to me for the last 3 upgrades in Visual Studio Enterprise 2017 (now again on upgrade to 15.9.21).
The fastest fix (and I'm not sure why) is simple and doesn't bomb your settings or take for ever.
In the Visual Studio Installer, click on Modify.
Click "Modify" on the bottom right corner.
Yes it says "Total space required 0 KB".
Yes you didn't really change anything.
It will then act like it is downloading something. (not sure what)
It will then act like it is installing something. (again, not sure what)
Open Visual Studio 2017 and it works.
Hope this helps.
If you have an offline installation like me and can't simply re-run the Visual Studio Installer you can edit devenv.isolation.ini and change the last line to read SetupFinished=true. It will detect your trickery and complain, but at least it will launch again.
Edit: I ended up getting the Visual Studio Installer to fix the issue after choosing the "Download then Install" option. Maybe I was too impatient when I initially stopped the update? My above answer is useful when you need to get work done that isn't affected by the broken features, but you will likely encounter problems later on.
just had the same problem (without any reason with) vs 2019 prof, after googling and reading on that topic, just went to vsix, looked for some individual component to install/uninstall, randomly picked cloud explorer, uninstalled it and some dependent components and VS 2019 prof started normally
decided to leave this here. may be it helps somebody
Solved: I did following steps, run the visual studio and it works for me.
In my case visual studio was working fine , I just restarted the PC, this popup was keep coming when I try to open visual studio.(in my case I was using VS 2019)
Go to this path "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE"
Open devenv.isolation.ini, set SetupFinished=true and save.
Now open visual studio.
Cheers!
In my case did following steps:
Clear temp files (you can %temp% in run command and Shift+Delete files)
Restart your computer
Open visual studio it will work properly.
Update: Faced problem again after couple of days, This time I go to C:\Program Files (x86)\Microsoft Visual Studio\Installer.
Click on retry.
Select one more feature which I had already installed on my Visual Studio
Click on modified and after installation it worked again.
This happened to me after I canceled a plugin update.
I solved by going to this site that has the latest update of Visual Studio.
https://learn.microsoft.com/en-us/visualstudio/releasenotes/vs2017-relnotes
I downloaded and upgraded it.
After that, Visual Studio worked.
If your VS is already upgraded, there´s an option to "repair" on the installer.
For this problem, goto uninstall screen in control panel right-click visual studio and select option change, Installer page will open now, In that window without changing anything click modify. it will solve the problem. I'm using VS Professional 2017
I got the same error today morning. This is what I did:
I ran the visual studio installer then I clicked on Modify.
The installer was showing 0KB Required. I continued and then it downloaded and installed. (Not sure what).
After that installation, it was able to launch.
I hope it works for you as well.
I was using Vs 2019 professional 16.6 and happened to me this issue one morning. I modified the installation by adding Azure Development tools even though I was not using it. This fixed the issue.
I just updated to 15.9.24 and I got this yet again, as I have my resolution above, and Visual Studio 2019 seems to be a lot better with avoid this issue. The installer for 2019 you do have to change something and do the modification, 2017 you don't have to change anything.
I reported this issue through Developer Community:
Setup not complete since 15.9.21
I don't know why but sometimes its buggy
it's up to date but after launch visual studio this error prompted !
you have to click modify in vs installer and just modify it.
its not going to download anything.
after a moment launch vs and enjoy :)
For VS2022, WIN11:
Control Panel > Programs > Programs and Features > Microsoft Visual Studio Installer
Then, click on Change and resume the previous process.
I wanna install Visual Studio 6.0 on my Windows 10 computer but I have some problems. If you can help me, I will be great. Firstly, I click to Setup file to install, and than I saw this screen below
I click "No". After that, I saw This screen below
And I click "Tamam (its mean "OK")" and than I saw this screen
And, after I wait 45 min, screen is shown like this in below
How can I install it on my Windows 10 computer ?
Computer is waiting like be locked as shown as like last picture
Install it on a Windows XP Virtual Machine. I think this is the last officially supported OS.
UPDATE
I could not find anything explicitly stating this, only this Visual Studio 6.0: Installation and Setup and this Microsoft Visual studio 6.0 on Microsoft Product Lifecycle
I think VS 6.0 was released in 1998 - Microsoft Visual Studio 6.0 on Wikipedia. I remember using it til 2004 when we upgraded to Visual Studio 2005. Which we now still have in some good old Windows XP MVs.
Visual Studio 2017 version 15.4 was released but my VS instance does not offer the update yet. How can I manually trigger an update?
Launch the visual studio installer (hit the windows key and type the name, you'll find it). It will then ask you to allow it to update itself, after which you will be offered the update.
You can update it from Notifications Hub left side of Visual studio.
In Notification Hub/Pane click on "Visual Studio Update" is available.
Or You can also update it from Visual Studio Installer.
https://learn.microsoft.com/en-us/visualstudio/install/update-visual-studio
Tools -> Extensions and Updates -> Updates
To update the core , let say from 15.4 > 15.9 , you need launch Visual Studio then
Help > Check for updates
To add\remove\update other sub component , you will need to run the Visual Studio installer and pick the require option.
Use the Visual Studio Installer
1-Open the installer.
2-In the installer, look for the edition of Visual Studio that you installed.

I've installed Visual Studio 2017 and I was playing with Diagnostic Tools. suddenly, after some restarts, the window does not open anymore and I don't figure out how to do it. Anyone knows how can I open it again ?
The selection is a bit hidden, it's in Debug, Windows, Show Diagnostic Tools. It should be with other window settings really to be easily found.
I just searched for hours for the Diagnostic Tools and did not find them in Visual Studio 2017. There was no menu entry in Debug --> Windows for me.
Finally, I wrote 'Diagnostics' into the Quick Launch bar and Visual Studio offered me to install this missing feature... I guess I forgot to check the tools on first installation!
If you're after a hotkey, the Diagnostic Tools can be reopened by default by pressing Ctrl+Alt+F2.
For other people struggling to find this. Microsoft might have changed how to open the Diagnostics window. Currently for Visual Studio 2019 I went to Debug > Intellitrace to open the missing Diagnostic window.
