mysql for visual studio 1.2.6 can't be deleted in registry

[wikywin]

I use the latest version of uninstaller to clean up visual studio 2013 from windows 10.
then I installed visuals studio 2017 enterprise and mysql for visual studio 1.2.8
but mysql for vs 1.2.8 failed to be installed(always prompted by "visual studio 2012, 2013, 2015 must be installed)
I googled all the solutions on the internet. none of them can solve my problem

finally I found a solution:
open registry to search mysql for visual studio in HKEY_LOCAL_MACHINE
deleted searched item for "mysql for visual studio 1.2.6"
then problem solved.

so uninstaller should deleted that registry item automatically.
