GameBrowser: "An unknown error prevented this game from launching"

[kevinmd88 20]

I went to launch a game last night and again this morning. I keep getting this error when I select "Play" on the game:

 

"An unknown error prevented this game from launching"

 

Here's the pertinent logs:

GameBrowser client (classic) plugin version 3.0.0.28

GameBrowser server plugin version 2.9.5110.13936

 

Let me know if I can provide any further info...

 

[EDIT]

Forgot to mention that if I call the emulator from the Run dialog/command prompt with the switches supplied and {rom} substituted with the full path to the game, it works fine...

What version of mediabrowser classic?

What version of mediabrowser classic?

 

3.0.108.0 B1-7.1

[Redshirt 1487]

The issue looks like it's due to changes made to GB months ago. For starters, I would suggest deleting your 

C:\ProgramData\MediaBrowser-Classic\Plugins\Configurations\GameBrowser.xml

and then re-launching the MBC configurator to re-enter your emulator switches. Hopefully that will pull down the correct console mappings from the server plugin.

[kevinmd88 20]

Just tried it Redshirt, unfortunately same thing still happening. Also pulled down the 3.0.117 update to Classic no luck there eother

[Redshirt 1487]

Can you please post a link to the gamebrowser plugin configs for both the server plugin and client plugin.

[kevinmd88 20]

Client:

Server:

http://pastebin.com/3fTaCRrf

[Redshirt 1487]

So it looks like the server and client xml configs are correct. The game data itself is the problem. 

 

It sucks, but you'll need to shut down server and delete all the xml files in your game libray (console.xml, platform.xml, game.xml) and then delete your library.db located in

C:\Users\[you]\AppData\Roaming\MediaBrowser-Server\data\library.db 

Once you restart and the scan media library task is complete, everything should be up and running again.

[kevinmd88 20]

Just tried this as well. Deleted *.XML from my Games folder and all subfolders, as well as library.db in that AppData folder... Library scan completed, but unfortunately it's still happening

[kevinmd88 20]

What else could it be?

[Redshirt 1487]

I honestly don't know yet. The dialog says "an unknown error", but that's not actually true. The error is triggered when the game can't match the correct emulator. Can you provide a new client log of you trying to launch a game. I'm hopeful the information is more revealing now that you've deleted all the xml files and rebuild your lib.

 

Also, does this happen for all game platforms, or just a few?

[Redshirt 1487]

Try with this version of GB. I don't think it'll fix the issue, but there's more logging info.

It happens every time for all platforms. I tried each one individually to make sure.

 

Does the GameBrowser plugin use any external libraries? Any specific .NET framework I can try to reinstall? Etc.?

@@kevinmd88. I've been trying to recreate this for days. Due to other server related testing I've deleted my database probably a dozen times and I cannot recreate this issue. It works for me every time, for every system I configure. So to be sure, did you follow the directions I laid out in previous posts. 

 

1. stop server
2. delete library.db
3. delete servers GameBrowser.xml
4. delete all .xml files contained anywhere in your game libraries
5. delete MBC GameBrowser.xml
6. start server
7. re-add all game directories to the Gamebrowser server dashboard config
8. wait for scan to complete
9. launch MBC configurator and add emulators to the various platforms.
10. Play game.

[kevinmd88 20]

I will try it again tonight but that's exactly what I did. I'll even try to make a screenvid of the process. Maybe I'll end up reinstalling the server or formatting or something...

I'm also having a problem with GB3 and wii emulator and games. I'm not on my htpc but I get an unexpected parameter error from dolphin when trying to launch my wii games from mb3.

I've tried on 2 different machines and get same popup white box error. The emulator works fine outside of mediabrowser. Its fetching all metadata correctly. It's just the launching of the game that's the problem.

I've read a few posts and can't decide is this an iso issue or switch issue? It's a standard server/classic install.

 

Any ideas ?

[Toro 0]

ok so I replaced the switch in the classic configurator with --exec="{rom}"   as per thread by Mithra62 and it seems to work on test computer.

Why isn't this info in the tutorial/guide thread ?

[jordandparker 5]

Im  Having the same error on all emulators aswell. Only since latest updates!. I also tried to roll back both server and mbc but still the same result.  I tried all of the above is there a fix or this yet?

[jordandparker 5]

For me the fix was that i needed to make the rom locations local on mb server in the game browser plugin under platform configuration not unc as they where previously. Hope this helps

[kevinmd88 20]

I forgot about this but just took a look at the issue here again recently. The error I was receiving had changed from "Unexpected parameter" (or whatever it was) now to "ISO mounter not correctly configured" (or something). This prompted me to wonder why it seemed to be treating the ISO images (for GameCube, at least) as if they were DVDs that needed to be mounted via DAEMON Tools (as configured in MBC Configurator). Sure enough, when I set the correct location for DT there, it tried to autoplay it that way. So, it would appear the library location isn't properly being recognized as a games folder or something?

 

Furthermore, when I went to look within my Game Boy, Nintendo 64, and other ROM game locations, it didn't detect anything - instead, said "No items found".

[Redshirt 1487]

I dont think GB is being loaded. Possibly an outdated version. I'd reinstall the plugin to make sure you have the latest version.

[Drexyl 4]

I too have been having this issue with GBC 3.0.0.38.

[Drexyl 4]

Okay, I have sorted out my issues.  Was a problem with initial library scans.

 

All good now.

If anyone else is seeing the same issue you should check your game.xml file and if your game system does not match what is in the configurator that might be your issue.  For instance mine use to be NintendoWii and it changed to Nintendo Wii and then the games worked fine.  I ended up just deleting all the game.xmls and let MBS repopulate them.
