I'm having a problem with VMware and the CS50 appliance.

I don't have anything fancy, like Fusion - just VMware Player 6.0.1 build-1379776. My computer runs Windows 7 Home Premium.

The player itself works fine but when I open the appliance file it shows the message, "Error while powering on: Internal error" as shown in the image below. How can I fix this error?

  • I don't use VMware Player anymore, but when I was using it, I got this very same error and I simply restarted my PC to fix it. I honestly didn't search for any other solutions, so there might be one out there other than restarting your PC, but until you find it, you may try restarting your PC and try again!

  • I answered already... Deleted it though. Kind of annoying. Anyway, @Kareem's solution worked! Thanks for helping!

  • I'm having the same problem! I have already restarted my laptop twice, but it's not working anyway. Does anyone know any further method to fix this?

I started the VMware Player in Administrator Mode and it worked.

  • I am now having the exact same problem. The appliance ran fine yesterday, but continues to give me an Internal Error every time I've tried today, even after rebooting my computer. If anyone has any other ideas on how to solve this, advice would be appreciated.

  • Starshadow, I tried again the next day. It didn't work, even after rebooting the computer. Maybe leave off for a couple of hours, then try again?

  • I actually ended up having to to a repair on the VMware Player - I've had to do it twice now. So you may need to do that (and keep the download file because it may be necessary to do it often until you get finished with the course). Very frustrating.

  • @Starshadow Can you post the details of how to "do a repair on the VMware Player" as a separate answer? That way it is easier for people to find, and they can vote it up if it works for them.

    @Starshadow: Could you please tell how to do a repair. I find VMWare to be brittle and crashes routinely, and I find no tools for recovery or repair!

You can follow:

Start -> Services.msc -> VMWare Authorization -> Click Start

  • This assumes it's not already running--a bad assumption. And restarting doesn't help me either.

Starting up the Vmware application in administrator mode solves the problem . So try exiting and start it up in administrator mode

In my case, my computer has a power cut off probably exactly when the virtual machine saved the .vmx file, so I have one .vmx~ and one corrupted .vmx file. Everything I need to change the .vmx~ to .vmx and delete .vmem and .vmss because previously I suspended the machine.
