The task script is locked by some application

This article applies to:

  • Acronis True Image Home 2012


  1. You open the Edit backup settings dialog or you are creating a new task;
  2. On an attempt to apply the changes by clicking Save, the product errors out with:

    Failed to deploy task


The product cannot receive exclusive access to the task scripts. As a result, an attempt to edit the task fails.

The backup task scripts have the *.tis file extension and are located at:

  • Windows XP: Documents and Settings\All Users\Application Data\Acronis\TrueImageHome\Scripts
  • Windows Vista, Windows 7: ProgramData\Acronis\TrueImageHome\Scripts

Most probably, you antivirus software has locked the task scripts.


  • Typically the script files can be locked by antivirus programs. To avoid locking in this case you will need to add the script files to the antivirus program exclusion list;
  • If the antivirus has not locked the script files, it could be some other process. You can try rebooting the machine to make the system release the script files;
  • You can also check what process has locked the script file by using the free Microsoft Process Explorer tool:
    1. Read about the tool and download it at Microsoft TechNet: Process Explorer;
    2. Once installed, click Find -> Find Hand or DLL (or just hit CTRL-F on the keyboard);
    3. Type in .tis in Hand or DLL substring;
    4. See what process has locked the file.
