VSPackage did not load correctly; How to revert "continue to show this error message" status?

Question

Today the VSPackage I'm developing failed to load, and Visual Studio prompted me to check ActivityLog.xml. It also asked "continue to show this error message?" And accidentally I pressed no.

The window I'm referring to looks similar to this:

How can I revert pressing "No"?

I couldn't find any switches in Tools>Options. This seems like a difficult phrase to search on google.

Answer 1

When you press No, Visual Studio creates a registry key HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\VS_VERSION\Packages{YOUR_PACKAGE_GUID} (e.g. HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\Packages{9A7EBB7F-B08C-4E35-9898-A7B73468A624}) with a value SkipLoading=1.

You need to delete this SkipLoading.

Just start Visual Studio with this switch:

devenv.exe /ResetSkipPkgs

For Visual studio 2017 or newer this is slightly trickier.

Close all instances of visual studio. Open regedit.

Select "HKEY_USERS".

From "File" menu select "Load Hive".

and locate visual studio's private registry hive file, which should be named "privateregistry.bin", could reside for example:

%LOCALAPPDATA%\Microsoft\VisualStudio\15.0_014d6a62\privateregistry.bin

15 = vs2017
16 = vs2019

rest of version is installation / configuration specific.

If you get error like this:

[Window Title]
Load Hive

[Content]
privateregistry.bin
This file is in use.
Enter a new name or close the file that’s open in another program.

[OK]

Need to wait visual studio to shutdown or close / terminate them manually.

in appearing dialog give some name, for example "vs2015_reghive"

Browse under path

HKEY_USERS\vs2015_reghive\Software\Microsoft\VisualStudio\15.0_014d6a62\Packages

and scroll all Packages in there and delete all "SkipLoading" keys there.

Then select your main key HKEY_USERS\vs2015_reghive, and from menu - "File" > "Unload Hive".

Start Visual studio normally.

I tried these steps and although they worked correctly, I was unable to find any SkipLoading keys, searching through. This is Visual Studio 2022 (there was only a packages folder in the config folder for that version). – Penitential
