Hi there,

I am using Window XP Profession and recently i can't seems to open up my device manager (Start->My Computer->Hardware->Device Manager).

It pop up a message "Windows cannot find 'mmc.exe.' Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search."

Note: I do not have the Win XP disc coz my friend DIY this com for me.

What i have done myself:
-Reboot my com (Doesn't work)
-tried Start->Run->devmgmt.exe (popped up the same message)


Can you please help me solve it?

Thanks in advance.

Note: I do not have the Win XP disc coz my friend DIY this com for me.

Use this link to Kelly's Korner. Go to line no. 107, on the right. Click the link and follow the installation instructions that are written at the top of the page.

I understand you don't have XP CD but I am afraid you must get one, of the same version, even if borrowed, to run further processes.

Placed the CD in the drive and click Exit when windows show up. Click Start > Run. In the command line type sfc /scannow (please note the space in the command) and press Enter. The computer will start now a long process of repairing corrupt or missing files. Let it run to the end.

Hi Skeptic,

My problem is solved. Thx. I contacted my friend who DIY my com and he transfer the missing mmc files to me thru TeamviewerQs. He said that i accidentally deleted the file somehow.

Well, i remember i read from somewhere that some spyware or norton actually delete these files from system32 because of threat risk or something like that. Or may i did accidentally delete it. Anyway its ok now.

Thx for your prompt reply tho

Regards,
Josh

My appologies for digging up an old thread but i noticed this was the exact problem i was having and all other forums have been stumped

after i enter sfc /scannow the windows file protection window appears and tells me its verifying all protected files are intact .....

now when the machine reboots i get no option of how to boot (cd or hdd) instead the machine automaticaly boots from the XP installation disc without me telling it to and from there there is no obvious method to fixing the problem as i do not want to overwrite the install i currently have loosing all my user created files etc

Take the cd out and reboot. The cd is not needed once the sfc is done

Once the scan has finished the system automatically reboots itself.. so in that time peroid i need to eject the win XP disc and then when the system boots up the process will continue?

I take it you have a Genuine Microsoft Xp cd you are using?
We can try a Repair Installation which will keep you data intact while fixing the OS system itself.
