virtualbox.org

I've just upgraded to 4.2.16 on Mac OS X.

Since the upgrade each time I attempt to logon to my VM I get the following error:

Failed to open a session for the virtual machine Windows.

No error info.

Result Code: NS_ERROR_CALL_FAILED (0x800706BE)
Component: ProgressProxy
Interface: IProgress {c20238e4-3221-4d3f-8891-81ce92d9f913}



Please help!!!!

Did you also upgrade the Extension Pack (I'm not talking about guest additions) ?

No, I don't believe so - how do I do that?

Thanks

I found the extension pack and installed OK, however the error is still the same when I try to start a VM

Thanks

The newly installed VirtualBox 4.2.16 will not run on my Mac OSX either. I turned to the internet for help and found this forum.

When I try to run a new virtual machine, this error crashes VirtualBox:
~~~~~~~~~~~~~~~~
Failed to open a session for the virtual machine New .

Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).

When I tried to install the extensions, this error crashes VirtualBox:
~~~~~~~~~~~~~~~~
Failed to install the Extension Pack /Downloads/06-08-2013/Oracle_VM_VirtualBox_Extension_Pack-4.1.26-84997.vbox-extpack.

Hope this helps someone identify my problem. Thanks for any help.

@ AlwaysLearning,
Run the Repair Disk Permissions using DIsk Utility on your MAC host then it should work.

Thank you, Perryg! That worked like a charm!

Repair Disk Permissions didn't fix the following error when installing the latest extension pack.

Extension Pack /Documents/Software/DMGs/Oracle_VM_VirtualBox_Extension_Pack-4.2.16-86992.vbox-extpack.

Failed to load the main module ('/Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib'): VERR_FILE_NOT_FOUND - dlopen(/Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib, 6): Library not loaded: /Applications/VirtualBox.app/Contents/MacOS/VBoxVMM.dylib
Referenced from: /Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib

Reason: Incompatible library version: VBoxPuelMain.dylib requires version 4.2.16 or later, but VBoxVMM.dylib provides version 4.1.23.
---------------
If the version of VBoxVMM.dylib is 4.1.23, which is later, shy should that throw an exception during installation, if
it passes the rule of 'VBoxPuelMain.dylib requires version 4.2.16 or later'?

The version of the extension pack must match the installed version of virtualbox. Do they?

Not sure. The download page has v4.2.16 VirtualBox and v4.1.26 for Extension pack.
I tried installing the v4.1.26 Ext pack and was successful.
Will see if the usb v2.0 support works with my vm.

Thanks.

You are not reading the download page correctly. Look for the link at the end of the first line in the Extension pack section.
