After installing KB4507460 on Windows 10 version 1607 and Windows Server 2016, when you launch the Logic App Editor from Visual Studio Cloud Explorer, it only displays a gray page without loading any content.
Microsoft has released KB4512517 to fix this issue. This is the recommended way to fix this issue.
This is a known issue of KB4507460. Microsoft has provided a registry key to work around this issue:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main Value: Disable Script Debugger Type: REG_SZ Data: no
However, this won't fix the issue of Logic App Editor because Visual Studio reads the registry key from a private hive. Even though we changed the registry key in
HCKU hive, Visual Studio would still get the value:
yes from the private registry hive:
We need following extra steps to change the value in Visual Studio private registry key file.
Ensure Visual Studio is closed.
Open Registry Editor, select HKEY_USERS, click File -> Load Hive.
%userprofile%\AppData\Local\Microsoft\VisualStudio, you will see one folder indicating the Visual Studio version,
15.0_566df79cin my case. Go inside this folder, choose privateregistry.bin.
Note: If you keep receiving warning that this file is in use even though you have already closed Visual Studio, please try reboot the machine.
Give the private registry hive whatever name you want:
vs_private_registryshould be the name you specified in step 4 and the
vs_versionshould be the same folder name as you found in step 3. Then change the value of
Disable Script Debuggerto no.
Then choose the root of
vs_private_registry, click File -> Unload Hive.
Then launch Visual Studio again, you will find the issue get solved.
Note: this is just a workaround for this issue, I will update this article once an official fix is available.
