Visual Studio 2015/2013 installation failed: A fatal error occurred during the installation of the Microsoft Visual Studio Assemblies Shell (Minimum) Interop

This error occurs when you reinstall the VS2015 when you have changed the unload load several times during installation:

Serious error occurred while installing Microsoft Visual Studio Minimum Interop Assemblies

Can not continue, online search for a very clear solution to view the log file to learn the error code and error messages:

0x80070643,could not open key:unknown\components\d2e60322f7884d115a04000972a8b18b\ C5fee661699fe093196fddd6df00e8b9

The decision is due to the fact that the registry does not have permission to access, which may cause some permissions to be set incorrectly, causing the next access to fail.

The workaround is to delete the registry key that accesses the error directly;

The corresponding registry location is Hkey_local_machine\software\microsoft\windows\currentversion\installer\userdata\s-x-x-xx\components\, Find the corresponding item;

The reload may have multiple local errors (that is, the item name, that is, d2e60322f7884d115a04000972a8b18b may be different), using the System Registry Editing tool regedit to open the path of the error is not accessible, you can one of the troubleshooting items cannot be accessed all deleted, You can also repeatedly install, encountered the failure in the view error log file to delete, anyway is trouble, perhaps a tool to quickly search is also good.

Because regedit cannot be accessed, operations such as changing the owner of a permission change will fail, so the pchunter is found on the internet (which is said to be done over the drive layer or using an undisclosed API), and the final reload succeeds.
