Uninstall game goes to Control panel/Uninstall list

[SylwesterZarebski]

Describe the bug
When I choose Manage install/Uninstall uninstaller is not run, but Control panel/Uninstall list is shown.

To Reproduce
Choose any installed Origin game, then Manage install/Uninstall.

Expected behavior
Uninstall game - the same as in Origin.

This may be problem of Origin platform, not GOG nor plugin, but still reporting this to check it out.

Well, its intentional. Origin do the same, at least for some games, for example Need For Speed Shift.

We didn't found browser protocol command for uninstall, so just use simplified "uninstall" for all.

[SylwesterZarebski]

It is true for only some games. Most of them are uninstalled right off from the client (Origin) without going to control panel.
I've checked this with Battlefield V (5) game. It is uninstalled right off from Origin and GOG goes to control panel.

Thanks for information. If it is limitation of protocol, it may be resolved in future.

[FriendsOfGalaxy]

Sure, but usually foreign clients do not need to implement "uninstall" command in browser protocol, so if it does not exists now, I wouldn't suspect this to appear in the near future.

But maybe it does exist? You can try out to find - we're accepting any ideas and PRs :)

Another way is to parse uninstall registry and just call proper UninstallString

which in case of Need For Speed shift will result in:

or without warning prompt if box was selected (in this case it is MsiExec.exe feature). Can you check if uninstalling Battlefield V from control panel flow is the same as uninstalling from Origin client?

[SylwesterZarebski]

Checking Steam plugin it looks like Steam have desired functionality, maybe Origin will have it in future.

PS. Uninstalling from Origin sometimes do not show usual window but some internal/styled one and uninstall immediately then. I'll check with Battlefield V or another game when i'll be home.

@SylwesterZarebski how the situation with uninstalling Battlefield/other custom uninstalled game?

[SylwesterZarebski]

Sorry for delay. I checked few other games (B5 is too big to download just for uninstall :-/) and it looks like executing uninstall from EA client is the same as from Control Panel.

Uninstall from Control Panel:

Uninstall from EA client:

All games which i've checked was executing EA Installer Cleanup tool:

Thanks for checking! I'll research how EA Installer Cleanup works in spare time to handle uninstall properly.

During EA Desktop research I found this in their logs after trying to uninstall UnravelTwo (steam version).

    73  [2021-05-20T09:21:52.383Z]   19652  INFO      (eax::services::gameManagement::readManifestFile) Reading manifest file: D:\Games\SteamLibrary\steamapps\common\UnravelTwo\__Installer\installerdata.xml.
    74  [2021-05-20T09:21:52.384Z]   19652  ERROR     (eax::legacyInterface::content::fillCatalogLocalUninstall)  Could not parse uninstallCommandLine=[] of offerId=[Origin.OFR.50.0002520]

It resulted in opening Control Panel. Looks like opening Control Panel is a fallback for getting unistall command from installer manifest.

Attaching the game manifest that EA Desktop couldn't parse: installerdata.zip

I wonder if looking for __Installer\installerdata.xml can be safely hardcoded in all Origin games. I've checked 2 games and it is there.

I have no time (for now) to implement this enhancement but it shouldn't be very difficult. And we can do better than EA Desktop (and Origin?), if we can parse manifest properly each time:)

UPDATE I'm not sure how it relates to EA Installer Cleanup
