APPLIES TO:
  • Parallels Desktop 10 for Mac
  • Parallels Desktop 9 for Mac
  • Parallels Desktop 8 for Mac
  • Parallels Desktop 7 for Mac
  • Parallels Desktop 6 for Mac
  • Parallels Access

Symptoms

I cannot install Parallels Tools. Installation hangs, rolls back, or stops with or without an error message.

Cause

  1. A process in Windows interfered with Parallels Tools installation. To minimize the risk of this kind of issue in the future, please do not perform any operations in Windows while Parallels Tools installation is in progress.

  2. There is a software conflict inside Windows.

Resolution

Follow these troubleshooting steps in this order:



Uninstall and install Parallels Tools

Note: We strongly recommend that you backup the virtual machine (See KB 4859) or create a snapshot(See KB 5691) before proceeding.

  1. Start your virtual machine and cancel the Parallels Tools installation wizard.

  2. Go to Start -> Control Panel -> Programs and Features (Add or Remove programs in Windows XP), then remove Parallels Tools from the list of apps.

  3. Restart Windows.

  4. Install Parallels Tools by clicking on Actions (Virtual Machine in Parallels Desktop 9 and earlier) -> Install Parallels Tools (See KB 112609 for guidance).



Disable antivirus and/or firewall software and third party services

If the issue persists, please try the following:

  1. Uninstall Parallels Tools per the instructions in the step 2, above.
  2. Disable, deactivate or stop any firewall and/or antivirus software installed in your virtual machine.
  3. Go to Start. Type the following in in the Search field: msconfig, then launch msconfig application.

  4. When the System Configuration window opens, switch to the Startup tab and uncheck all items listed there.

  5. Switch to Services tab, check "Hide all Microsoft services", then un-check all remaining third party services in the list.

  6. Click Apply, then OK.
  7. Reboot your Windows virtual machine and try to install Parallels Tools again.
  8. If the issue is fixed launch msconfig again and enable all necessary startup items and services.



Uninstall, clean up & install Parallels Tools

If the issue persists, please try the following:

  1. Uninstall Parallels Tools per the instructions above.
  2. Go to My Computer > "C" Drive > Program Files(x86) > Parallels folder and delete the Parallels Tools folder, if it's present.

  3. Go to Start. Type the following in in the Search field: regedit, then launch regedit application.

  4. In the Registry Editor, go to My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Parallels and delete the Parallels Tools entry. Then go to My Computer\HKEY_CURRENT_USER\SOFTWARE\Parallels and delete the Parallels Tools entry.

  5. Go to Start. Type the following in the Search field: cmd, then launch the cmd application with administrator privileges.

  6. At the Command prompt enter:

    sfc /scannow
    

    Hit Return and wait till the operation completes.

    if the sfc utility reports any errors, we recommend running it several times rebooting Windows after each attempt.

    Also try the solution in KB 117753

  7. Reboot Windows and try to install Parallels Tools again.



Uninstall, clean up, delete temporary files & install Parallels Tools

If the issue persists, please try the following:

  1. Follow the steps 1 through 4 from the previous section.
  2. Go to Start. Type the following in the Search field: %temp%, then hit Return. Select all files and folders in this Temp folder and delete them permanently (including from the Recycle Bin).
  3. Go to Start -> Computer -> Local Disk (C:) -> Windows and make sure it contains the "Temp" folder. Make sure a new parallels-tools-setup.xxxxxxxx_xxxxxx.log file (where xxxxxxxx_xxxxxx shows the date and time of file creation) created after each attempt to reinstall Parallels Tools.

    If the "Temp" folder does not appear inside the "Windows" folder you will need to create it manually.

    If a new parallels-tools-setup.xxxxxxxx_xxxxxx.log file is not created after each attempt to install Parallels Tools, rename the existing "Temp" folder (e.g.: "Temp.old") and create a new "Temp" folder manually.

  4. Install Parallels Tools manually by following KB 112609.



Note Launch PTAgent.exe or setup.exe files using the Run as Administrator option (right-click on the file, choose "Run as Administrator")
