Parallels Tools installation rolls back

APPLIES TO:
  • Parallels Desktop 9 for Mac

Symptoms

Parallels Tools installation rolls back without returning any error message or giving general Parallels Tools update error message.

To determine the cause of the rollback, you need to open the log file at C:\Windows\Temp\parallels-tools-setup.log. It will contain the following string:

    Error code 0xE0000100: The style of the INF is different than what was requested.

Sample:

    DIFXAPP: INFO:   Installing INF file 'C:\Program Files\Parallels\Parallels Tools\Drivers\prl_dd\prl_dd.inf' (Plug and Play).
    DIFXAPP: INFO:   Looking for Model Section ...
    DIFXAPP: INFO:   Installing devices with Id "PCI\VEN_1AB8&DEV_4005&SUBSYS_04001AB8&REV_00" using INF "C:\Windows\System32\DriverStore\FileRepository\prl_dd.inf_x86_neutral_caed5e8e38ace253\prl_dd.inf".
    DIFXAPP: INFO:   Will force install because driver is not better and force flag is set.
    DIFXAPP: INFO:   ENTER UpdateDriverForPlugAndPlayDevices...
    DIFXAPP: ERROR:  RETURN UpdateDriverForPlugAndPlayDevices. (Error code 0xE0000100: The style of the INF is different than what was requested.)`

Note: The component here, prl\_dd.inf\_x86\_neutral\_caed5e8e38ace253 is just an example. You need to check the parallels-tools-setup.log in order to find the exact component that cannot be installed in your case.

Cause

One or several files containing the cache for Parallels drivers are damaged as a result of an incorrect virtual machine shutdown or crash during Parallels Tools installation.

Resolution

Note: We highly recommend that you back up your virtual machine before continuing with these instructions.

Note: This solution applies to Windows 7 only

Section 1.

  • Upgrade your Windows 7 to Windows 7 Service Pack 1.
  • Restart Windows and check to see if the issue persists. Proceed with Section 2 if it does.

Section 2.

  • Remove Parallels Tools via the Control Panel.
  • Reboot Windows in your virtual machine.
  • Install Parallels Tools again using Parallels Desktop menu (Virtual Machine --> Install Parallels Tools).
  • Refer to Section 3 if the problem persists.

Section 3.

Try using DPInst:

3.1. Download dpinst.exe (or dpinst64.exe for 64-bit Windows) and place it somewhere you can access it inside Windows.

3.2. Open Command Prompt (in Windows, go to Start menu and find Command Propmt).

3.3. Type:

    cd /d <path to directory with dpinst>

3.4. In Windows Explorer, open C:\Windows\system32\DriverStore\FileRepository folder.

3.5. Multiple driver folders will be shown. Locate prl_pv* folder (there may be more than one):

prl_pv folders

3.6. Enter this folder.

3.7. In Command Prompt window, type:

    dpinst /d /u 

or dpinst64 for 64-bit Windows`.

3.8. From the Windows Explorer window, drag the .inf file from prl_pv folder onto the Command Prompt window so that it writes the path automatically:

DnD

3.9. Press Enter. A confirmation window may appear - press Yes.

3.10. Repeat steps 4.6. to 4.9. for every prl_pv folder found.

3.11. Reboot the virtual machine and attempt Parallels Tools installation again (you may also attempt to use msconfig to disable all 3rd party services and startup items as well as isolating Windows from Mac before rebooting).
