VMWare Player and incompatibility with BitDefender

I have a fresh install of Windows 7 64bit plus VMWare Player and BitDefender security software
VMWare player is able to install, but unable to open.

Here is the same error I have received and my replies.

Does anybody know why BitDefender would cause this?
Is there a workaround or configuration I should be aware of?

Any Links or assistance would be much appreciated :-)

Another thread ... (not resolved yet, although bitdefender seems like a likely culprit)

One thing to consider... I am presuming it is a BitDefender issue.

As I have performed a fresh install and also others are able to run VMware player on a Windows 7 64bit system, I have ruled out the OS as a consideration...

Try temporarily disabling bit defender
Your help has saved me hundreds of hours of internet surfing.

Disabling has no effect either :-(

I received this problem yesterday. Not with bitdefender and not with the new v4.0.4 update. Its a existing bug I havent looked at. Can you post your *.dmp file if it fits the limit?

Attempted using the trial version of VMware Workstation (an upgrade to VMware Player)

Similar problem occurred again?

Is the following link relevant? Appears to refer to USB controllers?


I cant take a look at the current dump until 3 days from now. Its possible that the VMware could not understand some of the drives instructions and caused it to go into a bugcheck. Disabling bitdefender only tells the driver to ignore filtering and does not remove the driver from memory.  Have you tried to actually remove all peripherals devices or disable those before VMware starts? You may have to try this several times to find out what is causing the problem. Until I get a chance to actually run the dump in a debugger I would definitely try running a few different scenerios with and without products added before the crash occurred. Are you saving snapshots to roleback with before you install new products like this?

No snapshots.

I looked at the dump. It looks like a threading issue, though I can't continue to check what exactly the problem is due to not having VMware Workstation, specifically "vmwarebase.DLL" as reported by the file dump. I also checked to see if there where any debug messages left and there was no trace of any. Sorry.
