Programmatically create a restore point


I checked around and even utilized/tweaked several solutions including the following, but I keep getting one of two errors. I either get

************** Exception Text **************

The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

The code I am using currently is as follows:

    // select local computer
    ManagementScope ManScope = new ManagementScope("\\\\localhost\\root\\DEFAULT");
    // create system restore point
    ManagementPath ManPath = new ManagementPath("SystemRestore");
    // select default options
    ObjectGetOptions ManOptions = new ObjectGetOptions();
    // create management class with previous options
    ManagementClass ManClass = new ManagementClass(ManScope, ManPath, ManOptions);
    // load function parameters
    ManagementBaseObject ManBaseObject = ManClass.GetMethodParameters("CreateRestorePoint");
    // description
    ManBaseObject["Description"] = "Check-In Tool Restore Point";
    // type of the restore point
    ManBaseObject["RestorePointType"] = 0;
    // type of the event
    ManBaseObject["EventType"] = 100;

    ManagementBaseObject OutParam = ManClass.InvokeMethod("CreateRestorePoint", ManBaseObject, null);

    restLabel.Text = "Restore Point Set: Yes";
catch (ManagementException err)
    restLabel.Text = "Restore Point Set: No - Error";

Edit: I updated my code from err.Message to err.ToString() and got some new information. The issue, apparently, lies within this line of code:

ManagementBaseObject OutParam = ManClass.InvokeMethod("CreateRestorePoint", ManBaseObject, null);

Any ideas?
