When running defrag, error "MMC cannot open the file c:\WINDOWS\system\dfrg.msc.

When I run the defrag I get a message that says "MMC cannot open the file c:\WINDOWS\system\dfrg.msc. It is perhaps because the file does not exist, is not the MMC, or was created by a later version of MMC.

Hello

I tried the steps before I posted my question, but it did not work. However, I downloaded SP3 again and it seems to work now.
Thank you

  • Error Msg: cannot open the file "Windows XP Professional - 000004.vmdk.

    The hard drive on my iMac crashed while my virtual machine is running.  When I try to open the virtual machine 'suspended', I get the following error message: could not open the file "Windows XP Professional - 000004.vmdk"; The system cannot find the specified file.  This file is listed in the contents of the packaging of the XP machine, but it notes the date, the iMac has crashed, which is the last day of work of the virtual machine.  I have read through discussions and tried a few things from the knowledge base, but I can't go past the error msg for the virtual machine to run.  Any suggestions?

    After selecting OK, I then received the second attached message, "Current Message.png", which reads... "your virtual machine has not returned because of an error.  If you believe that the error is correctable and you want to keep the suspended state, so you can correct the mistake, after that the virtual machine is turned off, select Preserve.  To ignore the waking state, select reject. »

    I didn't do anything since getting this second message because I do not know which to choose.

    In this case I'd throw away them.

    If after following your excellent detailed instructions & explanation (thank you!), here is what happened...

    As the machine has begun to resume in a suspended state, that asked me if I moved or copied and I selected, copied.

    In cases like this (restore a Machine virtual sauvegardΘ) the correct answer to this question is "I moved it" even thought "I copied it" seams more logical, it is not the right answer but with the advent of the second error message, not caused by the answer to the first question, no answer would have mattered.

    (if I can just get my prospects for work with this virtual machine files, your help would be invaluable!)

    This Virtual Machine is always recoverable, however if you are only interested in the recovery of data from the user then after reading the following quit VMware Fusion and try to mount the virtual disk to the Virtual Machine using the information below.

    Take a look at: VMware Fusion (menu bar) > help > Search > type VMDKMounter, and then select use VMDKMounter to mount a virtual drive as a Mac Volume

    Notice, ignore the parts on "to add support for reading / writing to NTFS volumes, you need to install NTFS - 3G separately." as it is not necessary for recovering files within the VM using VMDKMounter, because you only need read access to retrieve data from the user.

    After obtaining your user data disassemble the virtual hard disk on the desktop and then after that you want to retrieve the VM using methods from another just let know us and additional directions can be given.

    Hi JRCLNSIN100,

     

    Welcome to Microsoft Answers Forums.

    We would like to get some more information from you to help solve your problem. You better, please answer the following questions.

    ·         What is the disk you use to reinstall?

    ·         Is this a recovery or reinstalling the disc you are using?

    ·         When exactly do you get this error message?

    ·         What is the edition of Windows Vista, you try to install?

    ·         How old is the drive that you are using?

    ·         How are you starting the installation process?

    After researching the error 0x8007000D code is essentially due to file corruption and a problem with the drive itself.

    First check if you have scratches or dust on the disc and clean the surface and try again.

    To check if the disk is wrong, you will need to copy the contents of the DVD to the hard drive and try to install using that.

    To perform a flat installation of Windows Vista, follow these steps.

    Note The hard disk must have at least 3 GB of free space on the disk for the Windows Vista installation files. The hard disk must have at least 15 GB of additional disk space to install Windows Vista. For more information about system requirements for Windows Vista, see the Microsoft Web site at the following address:

    http://www.Microsoft.com/Windows/products/windowsvista/editions/SystemRequirements.mspx

    1. Insert the Windows Vista installation disc.
    2. Start Windows Explorer.
    3. In Windows Explorer, click to select the drive for the Windows Vista installation disc.
    4. On the Edit menu, click select all.
    5. On the Edit menu, click copy.
    6. Click to select the hard disk you want to contain the flat installation files.
    7. On the file menu, point to new, click the folder, type Windows Vista Setupand then press ENTER.
    8. Double-click the Windows Vista Setup program, and then click Paste on the Edit menu.
    9. Double-click Setup.exe, and then follow the instructions that appear.
