Hi,

I need help. I have installed VS 2015 Pro and 2017 Pro. Everything work fine befor install Windows update 1607 (Win 10 Pro x64). I will restore system using restore from Windows Update, but didn't help. 

VS 2017 rus fine, but VS 2015 is crash.  

I need SQL Managment Studio 16.5 or 17.0 (base on VS 2015 IDE) and this SSMS also crash. I try uninstall and install VS 2015 and SSMS without any result.

I delete folder: C:\Users\xxx\AppData\Roaming\Microsoft\VisualStudio\14.0 and C:\Users\xxx\AppData\Local\Microsoft\VisualStudio\14.0

I try reset setting VS 2015 IDE without result.

My log:

Do know any solution for this problem?

Hi Piotr,

If you start windows 10 in safe mode, does the issue persists?

Error 0x80070002 often means the system cannot find the file specified, please repair visual studio 2015 firstly. Meanwhile, disable any Anti-Virus or Anti-Spyware software on your computer. If the issue persists, I need your help to collect the complete installation log. Please usehttp://aka.ms/vscollect to gather the installation logs. After using it, you will find vslogs.zip under %temp% folder. Please upload the file to https://onedrive.live.com/ and share the link here.

Best regards,

Joyce
