Troubleshooting the 'Guitar Hero 3 Manager Songs Already Running' Error 'guitar-hero-3-dlc'

Are you experiencing an error message that says 'Guitar Harmonies III Manager tracks are currently active' whenever you try and start up Guitar Legend III on your computer? Do not worry - this is a relatively common issue with the game's auto-run feature, which can sometimes become stuck or misinterpret another program as being open in the background. In this article, we'll walk through some simple steps to resolve this problem so that you can get back to shredding those virtual strings.

Step 1: Close All Open Programs

First and foremost, make sure all other programs - including any music players or media software - are completely closed down before attempting to start up Guitar Hero III. Sometimes, another application might be using a system resource needed by the game's auto-run feature, causing it to think that GHIII is already running.

1a: Press Alt+Tab on Windows (or Command+Option+Esc on Mac) and close any open programs or windows.

1b: On your taskbar at the bottom of the screen (Windows only), right-click anywhere within the Notification Area icons area then select 'Task Manager'.

2. In Task Manager, look for any instances labeled as 'Guitar Hero III.exe', 'gh3.exe' or similar sounding processes under the Processes tab.

3a: Right click on these entries and choose 'End Process(es) to Force Close'.

Step 2: Uninstall/Re-Install Guitar Legend III

If closing all running programs still doesn't resolve your issue, it may be worth trying a full uninstallation followed by reinstallation of Guitar Hero III. This will remove any potentially corrupted files or registry entries that might be preventing the game from launching correctly.

1a: Open up Control Panel > Programs and Features (Windows) / Applications/Utilities/Remove 'Program' (Mac).

2b: Locate 'Guitar Legend III' within the list, then select it.

3. Click Uninstall/Uninstall again to confirm removal of all associated files and settings.

4. Once complete, restart your computer by shutting down completely via Start > Shut Down / Apple menu > Restart.

Step 3: Use Safe Mode

If neither Step 1 nor Step 2 above has helped resolve the issue, you might want to try launching Guitar Hero III in safe mode instead of relying on its auto-run feature. This will bypass any potential conflicts with other programs or drivers that may be causing problems:

For Windows:

a) Hold Shift while double-clicking the game's executable (.exe file).

b) A black Command Prompt should appear asking if you're sure you want to start Guitar Hero III in Safe Mode - type Y then press Enter.

For Mac (using Terminal):

1. Open Applications/Utilities/Terminal.

2. Type 'sudo /Applications/Guitar\ Harmonies\ III.app --safe' followed by Return and enter your password when prompted.

3. If asked again, select 'OK'.

Step 4: Perform a Clean Installation of Guitar Hero III DLC

If none of the above steps have resolved your issue, it's possible that one or more Downloadable Content (DLC) packs may be causing conflicts with the main game installation:

1a: Open up Origin/Steam/Xbox Live/etc. and sign in to your account.

2b Locate 'Guitar Legend III' within My Games/Libraries then right-click on its entry.

3c Select Manage DLC from the context menu.

Step 5: Re-Install Individual Guitar Hero III DLC Packs

If Step 4 above didn't resolve the issue, you can try re-installing individual pieces of DLC separately:

1a. Launch Steam/Origin/etc., log in with your account credentials if prompted.

2b Navigate to My Library > Games and click on 'Guitar Legend III'.

3c In the resulting window, select Manage then click on 'DLC' at top right.

So there you have it - a step-by-step guide covering all bases for resolving the pesky error message that says 'Guitar Hero 3 Manager songs are already running'. By following these simple troubleshooting steps and ensuring your system is free from any potential conflicts or corruptions, you should be able to get back into playing Guitar Legend III with ease. Happy shredding!
