Ignore this post. (I did a recovery of my computer and Blender is now opening.)
It was working fine the last few days since I dl’d it. But now I only get a C drive error message. I deleted Blender and downloaded it again. But I still have the same problem. I did delete an unwanted Browser bar that somehow got added to my Chrome browser yesterday or today. Right after that is when Blender failed to start up. Can someone tell me how to get Blender 2.66 to open?
