Getting "Error occurred in deployment step 'Install SharePoint Add-in': Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)" but the add-in still loads

Question

In the past, I was able to use Visual Studio to install apps (add-in) on my SharePoint online development site. However my Windows credentials got corrupted and I had to remove and add back in my Microsoft work accounts (I have two of them).

Now when I try to install an app, I get an "Error occurred in deployment step 'Install SharePoint Add-in': Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)" but the app still loads and I'm able to use Visual Studio to set breakpoints.

I uninstalled and reinstalled Visual Studio and still get the same error. I know the problem is something wrong with my computer. I'm looking for a way to track down what additional setting I need to change to get rid of this error message.

Hi @Eric Shen
Please refer to following steps to fix the issue

1. Shutdown all instances of Visual Studio
2. Delete %LocalAppData%\Microsoft\VisualStudio\15.0_f4938f75\privateregistry.bin file (the ID after 15.0_ may be different per machines)
3. Start VS as normal user

Before I uninstalled and reinstalled Visual Studio, I did run Repair on Visual Studio.
