Empty Device Manager and for error message "cannot create the enumerated device root need to install Parallels paravirtualization pilot".

Original title: Device Manager empty

I have Windows XP Service Pack 3 installed in a Bootcamp partition on my Intel iMac. I can detect and install new hardware such as USB keys. However, the Device Manager window is blank - how can I get the window to display the devices connected to the computer? I am also unable to install Parallels tools when I use Bootcamp as a virtual machine. The error message "cannot create the 'root-enumerated device' necessary to install Parallels Paravirualization driver.

Hey Harcjk,

For your first question, go through this article.

None of the items appear in the device list manager when you open

For the second question, here are some suggestions:

b. Click Start--> Panel--> Add / Remove programs and remove the Parallels tools in the list of applications.

c. restart Windows.

d. install the Parallels tools by clicking on the Virtual Machine--> install the Parallels Tools.

Method 2: Uninstall antivirus software

If the problem persists, try the following:

Temporarily uninstall all the antivirus software to the virtual machine and repeat steps of the "Uninstall & install Parallels Tools" section above.

Note: Don't forget to install the back antivirus software, once the problem is resolved.

 

Method 3: Uninstall, clean & install Parallels tools

  • Error message: cannot create the folder C:\Documents and Settings\Marlon\Local Application BVRP Software\NetWaiting\MoHlog.txt Settings\

    I recently had a problem with the virus 'Restore Windows'. I was able to get rid of it with Malwarebytes antivirus scanner, but when I turn on my computer I get this error message.
    Cannot create the folder C:\Documents and Settings\ of Settings\Marlon\Local Application BVRP Software\NetWaiting\MoHlog.txt

    I'm no expert, but I feel that my C drive disappeared, or at least has been hidden. My documents, pictures and music files are all empty. My programs (start > all programs) have been removed and deleted the shortcuts on the desktop. When I go to my computer, my personal and shared document files are not accessible. Under the description it says that they are hidden. My local disk (c) is also empty, but there is still very little space which suggests that programs and files have not been deleted.
    Is it possible to recover my files?
    Thank you

    Hello

    MoHlog.txt file is related to the software of modem on the computer, you can uninstall and reinsta it check if it works.

    Also scan your computer for any infection by virus still present on the computer using any scanner online.

    You can also try the system restore to the point before that the computer has been infected by the virus and check if it helps.

    Good luck!

  • Trying to install Zune. I get an error message 'cannot create the folder' and access is denied. Why.

    I just installed window7. reloaded many of my programs, but I am unable to load the Zune because it cannot create a folder. Why.

    [Moved from comments]

    I tried your suggestion. However, it did not work. I also did a disc clean after loading Win 7 32 bit and which did not help either. I solved the problem by creating a new folder in the program folder has no name but the left is like "new folder" Zune then installed in the folder. Trying to rename the new folder, it would not except Zune so I just named it 'Phone' Zune works well, thank you for your help.

  • ReferenceError: Error #1056: cannot create the title to the number.

    I have some problem with a table in one of my classes.

    Here are the details:

    JsonApi.as - my JSON class library and support wrapper functions for use with a Web service API.

    This is the skeleton of this file:

    (declaration of the class and constructor variables)

    // class variables
        static var apiRoot:String = "HTTP://";
        static var apiKey:String = "";
    
        public var MyArray:Array;
    
        public function QAPI()
        {
    
            trace("JsonApi => Constructor Called!");
    
        }
    

    the problematic function

    private function onComplete(e:Event){
    
     trace("JsonApi (onComplete) => Alive!");
     MyArray = new Array();
     trace("JsonApi (onComplete) => Array Made!");
    
     // get the data from the loader
     var loader:URLLoader = URLLoader(e.target);
    
     // we get errors here, so instead of Array type, must call it Object type
    
     var qData:Object = JSON.decode(loader.data, false);
    
    // for debugging, go through arrays to get the info we need
        for (var j:String in qData['items']) {
    
        trace("JsonApi (parsing) --> J is now: " + j );
    
        // get the ID from the sub array
        this.MyArray['id'] = qData['items'][j]['id'];
    
        // then fill in the rest of the data
        this.MyArray['id']['title'] = qData['items'][j]['title'];
        this.MyArray['id']['creator']  = qData['items'][j]['creator'];
        this.MyArray['id']['term_count']  = qData['items'][j]['term_count'];
        this.MyArray['id']['has_images'] = qData['items'][j]['has_images'];
    
        }
    }
    

    Now I forgot the code of this function which plots the data in the table of qData, but I know qData table is valid and that it has the information I need.

    My problem is the following:

    Error #1056: Cannot create property title on Number.
    

    that occurs on this line:

    this.MyArray['id']['title'] = qData['items'][j]['title'];
    

    I have google would be around, but cant figure try it as Google results say it has to do with the attempt to write in a private variable.  If you look at the decleration of class variable, you can see that I explicitly did PUBLIC.

    Please help me!

    (Thanks!)

    Hey,.

    I don't think you saw my second edition. Here is the code:

    private function onComplete(e:Event){
    
     trace("JsonApi (onComplete) => Alive!"); MyArray = new Array(); trace("JsonApi (onComplete) => Array Made!");
    
     // get the data from the loader var loader:URLLoader = URLLoader(e.target);
    
     // we get errors here, so instead of Array type, must call it Object type
    
     var qData:Object = JSON.decode(loader.data, false);
    
    // for debugging, go through arrays to get the info we need for (var j:String in qData['items']) {
    
      trace("JsonApi (parsing) --> J is now: " + j );
    
      // get the ID from the sub array  var id:int = qData['items'][j]['id']; this.MyArray[id] = new Object();   // then fill in the rest of the data  this.MyArray[id]['title'] = qData['items'][j]['title'];  this.MyArray[id]['creator']  = qData['items'][j]['creator']; this.MyArray[id]['term_count']  = qData['items'][j]['term_count'];   this.MyArray[id]['has_images'] = qData['items'][j]['has_images'];
    
      }}
    

    Copy and paste what it is and see if you get any change in the result. you always use the id as a string but use as the variable id with no quotes and remember to set up the table to a new object, so there dynamic fields. Good luck!
