I have installed VS 2017. But the installer can't find it, which results in that I can't update and uninstall them

Question

This is my Visual Studio UI and installer:

Then, I try to open the installer from Visual Studio. But it shows an error message:

I think that there is no specific path of the vs in its config files. However, I failed to find it. Please share your advice and a solution for this. Thanks.

Answer 1

Let's try this way - Open CMD with admin privilage and go to this path

cd /dc:\\program files (x86)\\microsoft visual studio\\installer

Depend on which version of visual studio you have installed (Enterprise, Community or Professional) type :

for Enterprise

vs_installershell.exe repair --installPath="C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise"

for Community

vs_installershell.exe repair --installPath="C:\Program Files (x86)\Microsoft Visual Studio\2017\Community"

for Professional

vs_installershell.exe repair --installPath="C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional"

here is the source it has worked for some users
