It's possible to encounter the "Sorry, there was a problem mounting the file" error message when mounting ISO file on Windows. What leads to this error message? How can one fix it? You're in the right place if you have the same questions. This tutorial from EaseUS will outline the main reasons for the error message. We'll then outline eight fixes you can apply to address the issue.
The error message implies that Windows has encountered setbacks when mounting an ISO or IMG file to make it available to the user. Only through file mounting can you view the contents of an ISO file on Windows.
Windows may fail to mount your ISO file due to the following reasons:
You'll need to fix these issues to mount your ISO file successfully. The next section will outline how you can do that.
Several ways exist to fix the ISO file mounting problem on your computer. This section will discuss eight fixes, including the following:
Sometimes, there could be a minor lag in File Explorer that is affecting the mounting process. You can restart it using the following simple steps:
Step 1. Launch File Explorer.
Step 2. Click on the Start Menu and select "Task Manager."
Step 3. Go to the "Processes" tab. Right-click on Windows Explorer (File Explorer) and select "Restart."
Step 4. Close Task Manager. Re-mount the ISO file to check if the error has disappeared.
You cannot mount an ISO file twice. If you try doing it for the second time, you'll likely experience the "Sorry, there was a problem mounting the file" error message. You must first confirm if you've already mounted the file.
You can do that by opening File Explorer and checking if a drive for your ISO file already exists. If the drive doesn't exist, that could not be the cause of the problem, so you can proceed to the next fix.
Some users have reported experiencing mounting error messages due to the existence of a Micro SD card. They say that ejecting the card helped in fixing the problem. If you're also experiencing the "sorry, there was a problem mounting the file" error message, you can try removing any SD card connected to your PC.
Making the ISO file "Read-only" could also fix the problem. Check the following steps:
Step 1. Find the ISO file. Right-click on it and select "Properties">"General."
Step 2. Navigate to "Attributes" and check the box for "Read-only." Click "Apply" then "OK."
Step 3. Repeat the mounting process to check if the error has disappeared.
Your system may sometimes block files downloaded from the internet without notice. Therefore, you can block such files automatically. Follow these steps to check if your ISO file is among the blocked components and unblock it.
Step 1. Find the ISO file and right-click on it. Select "Properties">"General."
Step 2. Check for a notification that your file "might be blocked" next to the "Security" option. Uncheck the "Unblock" box to change the setting. This will unlock your ISO file.
Step 3. You can repeat the mounting process to check if the error has disappeared.
If you've set your ISO image with a sparse attribute, it may fail to mount successfully. You can remove the sparse attribute via CMD as follows:
Step 1. Launch CMD as an Admin.
Step 2. Type these commands and press Enter after each of them (replace "PathToYouISO" with the correct drive path for your ISO file):
Step 3. The first command helps you determine if a sparse attribute exists, while the second removes it.
Note: You can also remove the sparse attribute by copying your ISO file to a different location and re-mounting it.
Your ISO file is usually assigned a drive letter after a successful mount. You'll encounter the sorry error message if there is a conflict between the drive letters assigned. You can fix this by changing the drive letter as follows to change drive letter:
Step 1. Right-click the Start menu. Choose "Disk Management."
Step 2. Find the conflicting drive letter and right-click on it. Select "Change Drive Letter and Paths."
Step 3. Select "Change" and pick a new drive letter. Hit OK to confirm your selection. Exit Disk Management and repeat mounting the ISO file to see if the error has disappeared.
The error message may also emerge due to a corrupted disk image driver. You can try repairing it via the Windows Registry Editor as follows:
Step 1. Hit Win + R. Type "regedit" on the Run box and press Enter. This will launch the Registry Editor.
Step 2. The first step is to create a registry backup. Visit the "File" tab and select "Export."
Step 3. Choose a name for your backup file. Set the "Export range" to All, then click "Save."
Step 4. Next, paste the following subkey and hit Enter:
Step 5. Navigate to the right panel and right-click on "UpperFilters." Select "Delete." Repeat this process for the "LowerFilters."
Step 6. Exit Registry and restart your PC. You can then retry the mounting process.
