Debug in Visual Studio disabled 10.2.1.7

I’m trying to open a customization in Visual Studio. I have Visual Studio Professional 2017 installed on my machine. In Epicor I go into developer mode, open the application and am taken to the Select Customization dialogue. I can highlight any available customizations, but the “Debug in Visual Studio” is grayed out, disabled. What else do I need to have set/configured to enable the “Debug in Visual Studio”?

  1. Try rebooting (if you just installed VS and didnt reboot yet)

It should work - also see thread

What version of Epicor?
There are only certain version of visual studio that work with it.

I think the previous post leads to this but check if this key exists in the registry

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\DevDiv\vs\Servicing\15.0\Core

It does not—does the “15.0” in that entry refer to the version?

We are on 10.2.1.7.

That is not a valid Epicor version…10.2.100.7?

Doh! Sorry, 10.2.100.7

15 means VS2017. On a standard install you should have that key.

You can try manually adding that key - but make sure you have rebooted and it still does not exists.

Microsoft Blip:
You can also check simply that VS2017 is installed by verifying the key HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\DevDiv\vs\Servicing\15.0\Core@Install is set to 1

I will give that a shot, thank you

No, still nothing. Am I setting it correctly?

Should have added that it did not exist after reboot, so tried to manually add.

Sorry - add like this. Instead of 14 you should have 15

I’m sorry, still no go:
