How to register PaintDotNet.ShellExtension.x64.dll manually?

[xchellx]

How do I register PaintDotNet.ShellExtension.x64.dll manually? regsvr32 does not like it (missing `DllRegisterServer` entry point),and regasm requires a C# DLL.

[Disk4mat]

Im figuring there is some reason for not installing the app. Did you open the command prompt as an admin?

Yes, from Windows Key + R -> cmd.exe -> Ctrl + Shift + Enter -> UAC Prompt:

C:\Windows\system32>cd C:\Users\xjonx\AppData\Roaming\paint.net

C:\Users\xjonx\AppData\Roaming\paint.net>regsvr32 PaintDotNet.ShellExtension.x64.dll

C:\Users\xjonx\AppData\Roaming\paint.net>

I get:

---------------------------
RegSvr32
---------------------------
The module "PaintDotNet.ShellExtension.x64.dll" was loaded but the entry-point DllRegisterServer was not found.

Make sure that "PaintDotNet.ShellExtension.x64.dll" is a valid DLL or OCX file and then try again.

OK

And from Start -> Visual Studio 2022 -> Developer Command Prompt for VS 2022 -> Right Click -> More -> Run as administrator -> UAC Prompt:

And yes, I do have paint.net installed portably so I can move it to a new computer (copying over %APPDATA%) without having to reinstall it (makes setting up a new PC easier).

This is for registering the thumbnail handler for a portable copy of the app

[Rick Brewster]

When you install the app with the regular installer EXE, it will create a log file called C:\Windows\SystemTemp\pdnSetupActionsInstall.log. This contains, among other things, all of the registry entries it creates (or deletes, if updating or uninstalling).

 

Start with the line containing the text RegistryHandler::Register and you'll see what registry entries are created, and how it is associated with each file extension. You won't need all of them but it should be reasonably obvious.

Is there any way I can "dry run" the installer to figure this out? I do not want to modify my current environment just to figure this out. Or can you list the specific entries it modifies?

[Rick Brewster]

No, there's no "dry run".

 

Here's what it produces on my system though. Not all of it is needed for the thumbnail handler, such as the entries for the "protocol"  and RegisteredCapabilities. None of it would be harmful, however. All strings are surrounded in double-quotes, so if you see a string with double-double quotes like ""this"" that just means that the string added to the registry is actually "this". There's no other escaping or formatting for the strings beyond that.
