Using the Allow CORS: Access-Control-Allow-Origin Extension

Accessing the Extension Page

To begin, you need to access the extension page. Depending on your web browser, you can visit the dedicated web store (Google's Chrome Web Store, Firefox's Add-ons Manager, etc.) to find the Allow CORS: Access-Control-Allow-Origin extension. You can copy and paste the extension's name into the search bar at the top of the web store's webpage.

Adding the Extension to Your Browser

Once you've found the Allow CORS: Access-Control-Allow-Origin extension, click the corresponding "Add to Chrome" or "Add to Firefox" button. A dialog box will pop up, asking you to confirm the action. Read through the permissions the extension needs to function properly, and if you agree, click on the "Add Extension" button.

Confirming the Addition of the Extension

After successfully installing the extension, a new icon should appear on your browser's toolbar. This icon indicates that the CORS extension is now part of your browser and ready to use.

Logging into Your Minecraft Account

With the Allow CORS: Access-Control-Allow-Origin extension now part of your browser, launch a new tab on your browser and browse to the Minecraft login page. There, input your account credentials to sign into your Minecraft account.

Activating and Enabling the Allow CORS: Access-Control-Allow-Origin Extension

Since you've just installed the extension, you'll need to manually turn it on for the first usage. To do this, locate the new icon on your browser's toolbar (representing the newly installed extension) and click on it. A drop-down menu will appear. From this menu, ensure that the "Enable CORS" option is turned on.

Reloading the Minecraft Page

With the Allow CORS: Access-Control-Allow-Origin activated, return to the tab with the Minecraft login page and then refresh it. You should now be able to proceed with no issues.

Error Handling

If the error persists, consider toggling off and on the extension and reloading the page. You're also advised to clear any cache or cookies, as these could potentially be interfering with the functioning of the extension or the Minecraft website. Alternatively, trying another browser or device may help pinpoint the problem's source.

Restarting the Minecraft Launcher

Closing the Error Message and Quitting the Minecraft Launcher

The first step in troubleshooting the "Failed to create profile" error is to close the Minecraft launcher completely. Begin by closing any error messages that you may see. Then, quit the Minecraft Launcher by clicking on the 'X' button in the top right corner of the program window. If the launcher is not responding, you can use the Task Manager on Windows to end the task. To do this, right-click the Start Menu icon and select Task Manager from the menu. Locate the Minecraft process in the list, select it, and click the "End task" button.

Waiting and Relaunching the Minecraft Launcher

After closing the Minecraft Launcher, it's recommended that you wait for a few moments before relaunching the program. This gives your system time to completely end any lingering processes related to the launcher and ensures that you start anew when you reopen the program. To relaunch the Minecraft Launcher, locate the program icon on your desktop or your system's program list and double-click it.

Trying to Create a New Profile

Once the Minecraft Launcher has been successfully relaunched, attempt to create a new profile. During this process, the system will establish a new connection with the game server, which should resolve any transient issues that may have been present. If the error message still appears at this point, it may suggest persistent problems that require further troubleshooting.

Alternate Solutions

If restarting the Minecraft Launcher does not resolve your issue, consider other potential solutions, such as using a browser to create a new profile on the Minecraft website. Remember to disable all extensions and clear cache and cookies in your browser before attempting this. Alternatively, you can try this process on a different device, like your smartphone, to see if the problem lies with your primary device.

Running the Minecraft Launcher as a System Administrator

Locating the Minecraft Launcher in the System

If you're dealing with the "Failed to create profile" error, there is a possibility that running the Minecraft Launcher with administrative privileges will resolve this issue. You can find the Minecraft Launcher by inputting "Minecraft" in your system's search box. The quickest way to access this search box is by simultaneously pressing the Windows key + S on your keyboard.

Running the Minecraft Launcher as an Administrator

Once you've located Minecraft Launcher in the search results, you need to grant it administrative privileges.

1. Right-click on the "Minecraft Launcher" from the list of results.
2. Select "Run as administrator" from the drop-down menu.

Depending on your system's User Account Control settings, a prompt may appear to confirm that you want to allow the application to change your device. If this prompt shows up, select "Yes" to proceed.

Creating a Profile With Administrative Privileges

Now that the Minecraft Launcher is running with administrative privileges, you can try to create a new profile. Initiate the process as usual: Click the profile button, then "Add Profile," and provide the necessary details. If the issue stemmed from a lack of system permissions, running the launcher as an administrator should adequately address the problem.

Applying Further Error Solutions

If running the Minecraft Launcher as administrator does not resolve the persistent error, you may want to uninstall your current launcher version and replace it with the Windows 7/8 version, especially if you have been using the Minecraft Launcher for Windows 10/11. This method can bypass any unexpected bugs plaguing the newer versions of the launcher.

Using a Browser to Log Into Minecraft and Create a Profile

Opening a Browser and Accessing the Minecraft Login Page

If you're having trouble creating a new profile through the Minecraft Launcher, consider logging in and creating a new profile directly through your browser. First, open your preferred browser. In the URL box, type in the Minecraft website address or simply carry out a web search for 'Minecraft login' and select the appropriate page.

Logging in with Mojang Credentials or Microsoft Account

Once you are on the Minecraft login page, enter your account details. If your Minecraft account was created using your Mojang credentials, use those to log in. However, if your Minecraft account was created with your Microsoft account, use that instead. After entering your credentials, click the 'Log in' button.

Navigating to the Games Tab

Upon successful login, find and click on the vertical button on the screen's left-hand corner. A side menu should pop open. Look for the "Games" tab and select it.

Changing Your Minecraft Edition Profile Name

In the Games tab, find your Minecraft edition from the list presented and click on it. A new screen will open with a list of options related to your Minecraft edition. Look for the "Profile Name" option. Clicking on this should open up an edit field.

Saving the New Profile Name

In the edit field, type in your new preferred profile name. Ensure it complies with Minecraft's rules regarding profile names- no offensive words, appropriate length, unique, etc. Once you're satisfied with your choice of a new profile name, save the changes by clicking on the "Save" or "Change Profile Name" button.

Verifying Profile Change in Minecraft Launcher

After saving your new profile name, log out of Minecraft in your browser. Relaunch the Minecraft Launcher and log in again. Ideally, you should now see the new profile name in your Minecraft Launcher, indicating a successful profile change.

Logging Out and Logging Back Into the Minecraft Launcher

Finding Your Account ID

If you are having trouble creating a new profile in Minecraft, a simple solution might be logging out and then logging back in. This process can help to clear any misconfigured files in your account. To start, open your Minecraft Launcher and locate your account ID, usually found in the top right corner of the launcher's interface.

Logging Out of Your Account

Once you've found your account ID, click on it to reveal a drop-down menu. From this menu, select the "Logout" option. This will sign you out of your Minecraft account and take you to the default launcher page.

Logging Back into Your Account

Next, attempt to log back into your Minecraft account. From the default home page of the Minecraft Launcher, locate the "Log In" button and click on it. Click "Log In" after entering your account's credentials. Make sure to enter your account credentials correctly to avoid any login issues.

Checking if the Problem is Solved

After logging back in, attempt to create a new profile. If the problem persists, this approach has failed to solve the issue, and you might need to try more troubleshooting methods. But if you can successfully create a new profile in Minecraft, logging out and logging back in will resolve the issue.

Possible Further Steps

If the issue persists after this step, try the other troubleshooting methods, such as running the Minecraft Launcher as an Administrator, changing to a different Minecraft Launcher version, or possibly reinstalling the game if the issue persists after trying all methods.
