Can't install any plugin - hash mismatch
-
Hi,
I get the following error when trying to install a plugin from the Plugin Admin tool. I’ve tried several including Compare, JSON Viewer, 3P, HEX-Editor, JSON Tools.
This has been happening for several months across multiple app versions. I see there are several historical posts about this but not seeing a resolution. Any way to install plugins manually, or will I just run into the same issue?

Your Debug Info shows that you are using 64-bit Notepad++ version 8.8.8; Plugins Admin in that version should be offering Preview HTML 1.3.3.3. From your screenshot, it looks like it’s trying to load a 32-bit plugin with version 1.3.2.0.
I’m thinking that somehow your copy of the plugins list is not getting updated properly. Just to be sure… is this a regular installed version or a portable version, and exactly where are you getting the download?
Any way to install plugins manually, or will I just run into the same issue?
You can install plugins manually and there isn’t a hash check when you do that. Before we go that way, though, we need to figure out why your installation copy of the plugins list is messed up — I have to think it might not be the only thing that’s messed up.
