Problem Description

Hello, today I tried to update a bunch of plugins for Flow Launcher by pm update command and I've got an error of Explorer plugin:

Everything Search Exception:

When I tried to reinstall Explorer plugin by Plugin Manager, I've got the exception message:

Are you using the regular or portable version of Flow?

[Rhynorater]

I'm also having this problem - using the desktop version. Not portable.

[cccxp]

Got same issue on Flow Launcher 1.18.0 portable version.
pm update Explorer will break Explorer Plugin, and pm update Plugins Manager will break itself.

• Plugins Manager: 3.1.1 to 3.2.0
• Explorer: 3.1.6 to 3.2.0

[mossadforsale]

Are you using the regular or portable version of Flow?

portable

[deefrawley]

Yeah I'm getting this too since updating.

[royalishere]

I'm having the same issue on desktop version. Explorer plugin 3.2.0

[nanoraptor]

How to downgrade the plugin???

[Drigva]

Same issue:

Flow Launcher: 1.18.0 portable version.
Plugins Manager: 3.2.0
Explorer: 3.2.0

[nanoraptor]

For those who want to downgrade to the previous version for the time being, download Explorer v3.1.6 zip from here.

First Close Flow Launcher from the task manager (All procesess should be terminated)

For Regular users:
1)Go to C:\Users\{User_name}\AppData\Local\FlowLauncher\app-1.18.0\Plugins Delete Explorer-3.2.0 and create a new folder Explorer-3.1.6
2)Transfer/Extract all the 'contents' of the zip file to the newly created folder Explorer-3.1.6

For Portable users:
1)Locate the FlowLauncher\app-1.18.0\Plugins and delete FlowLauncher.Plugin.Explorer and extract the zip file in the same directory

Now start the flow launcher again from the start menu
You can do the same for plugins manager too. Download zip v 3.1.1 from here.

[taooceros]

You can install with pm install <url of zip> directly.

[nanoraptor]

You can install with pm install <url of zip> directly.

The manager itself seems to be broken

My apologies everyone, I bumped the Explorer plugin in the dev branch as part of the new release and it appears you updated to the latest Explorer version before I was able to finalise the 1.19.0 release. The updated Explorer plugin actually depends on parts of the Plugin API that is not released yet and that's why there were errors.

To resolve this issue, just upgrade flow to 1.19.0. Future default plugin releases will also follow the timeline of flow's new releases, so we won't get this problem again.
