Using TBIView in Windows to open the backup results in the following error message:<\/p>\r\n  <blockquote>\r\n    <p><font color=\"#ff0000\">You don't have permission to open this file.<br \/>Contact the file owner or an administrator to obtain permission.<\/font><\/p>\r\n  <\/blockquote>\r\n  <p>Double-clicking on the image file in Explorer to launch TBIView results in the following error message:<\/p>\r\n  <blockquote>\r\n    <p><font color=\"#ff0000\">Insert media 1 containing file [backup path and filename]<\/font><\/p>\r\n  <\/blockquote>\r\n  <p>Clicking OK will repeat the message. Clicking Cancel will display two additional error messages:<\/p>\r\n  <blockquote>\r\n    <p><font color=\"#ff0000\">Unable to open file<\/font><\/p>\r\n    <p>and<\/p>\r\n    <p><font color=\"#ff0000\">Error 6 opening file [backup path and filename]This usually means the file is not accessible or the file is invalid.<br \/>Ensure the file exists and the user has read permissions; Update to the<br \/>latest version of TBIView; Consider checking or replacing system RAM.<\/font> <\/p>\r\n  <\/blockquote>\r\n  <p>Attempting to open the backup using TBIMount results in the same errors. Trying to copy or delete the backup will usually result in permission errors. <\/p>\r\n  <p>Similar errors and access issues can also occur with other files created outside of Windows. Trying to access a drive that originated on another system will usually just report an <em>Access denied<\/em> message (the drive will not show normally in Explorer).<\/p>\r\n  <p><strong><font color=\"#ff5500\">Cause:<\/font><\/strong> <\/p>\r\n  <p>The drive, folder, or file does not have the necessary access permissions. Additionally, the ownership of the item may be incorrect.<\/p>\r\n  <p><strong><font color=\"#ff5500\">Solution:<\/font><\/strong><\/p>\r\n  <p>For image files, it may be possible to access the file by running TBIView\/TBIMount as an administrator. To do this, right-click on the program icon or shortcut and select <strong>Run as administrator<\/strong> from the pop-up menu.<\/p>\r\n  <p>To take ownership of the drive, folder, or file and set the permissions to allow normal access, follow the instructions below.<\/p>\r\n  <p><strong>Note:<\/strong> If you are logged in as a standard user you will need to provide an administrator password to perform several of the steps below. Alternatively, you can log in as an administrator before you begin (recommended).<\/p>\r\n  <p><font color=\"#005858\"><strong>Using Explorer<\/strong><\/font><\/p>\r\n  <p>&nbsp;&nbsp;&nbsp;<strong>To take ownership:<\/strong><\/p>\r\n  <ol>\r\n    <li>Open Explorer and browse to the drive, folder, or file. Right-click on it and select <strong>Properties<\/strong> from the pop-up menu. <br \/><br \/><\/li>\r\n    <li>Click the <strong>Security<\/strong> tab. <br \/><br \/><\/li>\r\n    <li>Click the <strong>Advanced<\/strong> button. The Advanced Security Settings dialog opens. <br \/><br \/><\/li>\r\n    <li>In Windows Vista and Windows 7, click the <strong>Owner<\/strong> tab and then click the <strong>Edit<\/strong> button.<br \/><br \/>In Windows 8.x\/10\/11, click the <strong>Change<\/strong> link at the top of the dialog where the Owner is displayed. <br \/><br \/><\/li>\r\n    <li>Select the new owner. If changing ownership on a drive or folder and you wish to include all subfolders and files contained within it, select the <strong>Replace owner on subcontainers and objects<\/strong> option (on Windows 8.x\/10\/11, this option is available under the <strong>Change<\/strong> link after you change the owner). Click <strong>OK<\/strong>. <br \/><br \/><\/li>\r\n    <li>If a Windows Security message box is displayed informing you that you need to close and reopen the properties, click <strong>OK<\/strong> to close it. When setting ownership on a drive there may be message that permissions will need to be modified (allow it to make the changes). <br \/><br \/><\/li>\r\n    <li>Close the Advanced Security Settings dialog and the Properties dialog. <\/li>\r\n  <\/ol>\r\n  <p>&nbsp;&nbsp;&nbsp;<strong>To set file permissions:<\/strong><\/p>\r\n  <ol>\r\n    <li>Right-click on the drive, folder, or file in Explorer and select <strong>Properties<\/strong> from the pop-up menu. <br \/><br \/><\/li>\r\n    <li>Click the <strong>Security<\/strong> tab. <br \/><br \/><\/li>\r\n    <li>Click the <strong>Edit<\/strong> button, then the <strong>Add<\/strong> button. <br \/><br \/><\/li>\r\n    <li>In the Select Users or Groups dialog, enter the new user or group to which permissions need assigned. For example, you may enter your <em>username<\/em>, <em>Users<\/em>, or <em>Everyone<\/em>. Click the <strong>examples<\/strong> link if necessary. Click <strong>Check Names<\/strong> to verify the entered name is valid if you're unsure. Click <strong>OK<\/strong> when finished. <br \/><br \/><\/li>\r\n    <li>Back in the Permissions dialog, you can now select the user or group you added and then select the permissions to allow for the file (e.g. Allow - Full Control). Click <strong>OK<\/strong> when finished. <br \/><br \/><\/li>\r\n    <li>Close the Properties dialog.<br \/><br \/><strong>Note:<\/strong> If you need more control over setting permissions (e.g. specifying recursion for a folder) you can click the <strong>Advanced<\/strong> button on the <strong>Security<\/strong> tab (Step 2, above) and make the changes from the <strong>Permissions<\/strong> tab. <\/li>\r\n  <\/ol>\r\n  <p>You should now be able to access the drive, folder, or file normally. If you changed a drive or folder and didn't recurse folders you can repeat the steps above as necessary to gain access to the desired files.<\/p>\r\n  <p><font color=\"#005858\"><strong>Using the Command Prompt<\/strong><\/font><\/p>\r\n  <p>The instructions below use a sample image file (<font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>D:&#92;System Backup.tbi<\/strong><\/font>) and folder (<font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>D:&#92;Backups<\/strong><\/font>). When running the commands make sure to use the drive, folder, or file that needs modified on your system.<\/p>\r\n  <ol>\r\n    <li>Open an Administrator Command Prompt.<br \/><br \/><\/li>\r\n    <li>To take ownership of the file run the following command. The new owner will be the current user\/administrator.<br \/><font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>takeown \/f &quot;D:&#92;System Backup.tbi&quot;<\/strong><\/font> <br \/><br \/>To give ownership to the Administrators group specify the <font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>\/a<\/strong><\/font> option:<br \/><font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>takeown \/f &quot;D:&#92;System Backup.tbi&quot; \/a<\/strong><\/font><br \/><br \/>When taking ownership of a drive or folder you can recurse directories by specifying the <font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>\/r<\/strong><\/font> option. For example, to take ownership of the <font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>D:&#92;Backups<\/strong><\/font> folder, subfolders and files, run:<br \/><font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>takeown \/f &quot;D:&#92;Backups&quot; \/r<\/strong><\/font> <br \/><br \/>For more information on using takeown, run <font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>takeown \/?<\/strong><\/font> at the prompt. <br \/><br \/><\/li>\r\n    <li>To set the file permissions run the following command:<br \/><font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>icacls &quot;D:&#92;System Backup.tbi&quot; \/grant users:F<\/strong><\/font><br \/><br \/>The above command grants Full Control (F) to the <em>Users<\/em> group. You can also specify a user if you wish. For example, if the username is John:<br \/><font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>icacls &quot;D:&#92;System Backup.tbi&quot; \/grant John:F<\/strong><\/font><br \/><br \/>If you need to set permissions recursively, specify the drive or folder and the <font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>\/t<\/strong><\/font> option:<br \/><font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>icacls &quot;D:&#92;Backups&quot; \/grant users:F \/t<\/strong><\/font><br \/><br \/>For more information on using icacls, run <font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>icacls \/?<\/strong><\/font> at the prompt. <\/li>\r\n  <\/ol>\r\n  <p>You should now be able to access the drive, folder, or file normally. <!-- END COPY HERE -->If you changed a drive or folder and didn't recurse folders you can repeat the steps above as necessary to gain access to the desired files.<\/p><hr \/>\r\n  <p><strong><font color=\"#ff5500\">Additional Notes:<\/font><\/strong><br \/><\/p>\r\n  <ul>\r\n    <li>Be careful when using recursion to change ownership and permissions since it may change many files\/folders on the drive. Make sure the target drive or folder is correct before running the command. Note that all folders and files may not be changed (some System files\/folders will usually be blocked).<br \/><br \/><\/li>\r\n    <li>Advanced users may wish to create a CMD script to run takeown and\/or icacls on a specified path. For example, if backups are regularly placed into <font color=\"#008800\" face=\"Courier New, Courier, monospace\"><strong>E:&#92;Offline Backups<\/strong><\/font> using Image for DOS and they require fixing, a script could be created to run takeown and icacls on the folder.
