Hya!

Im being told by windows 8 that nvcuda.dll is missing and to reinstall the program, this is just after Nvidia upgraded their drivers for my GeForce GT 650M, the update came out yesterday I think.
Anyhow reinstalling didn't fix the problem.

Any suggestions?

Cheers and thanks!

I guess I should mention that this happens when I try to start the program and its preventing me from even running it.

Ok this is stupid:
The Nvidia control panel popped up and told me to update my drivers and I being an airhead did as I was told (I suppose they could have told me to do something much worse). This broke Octane, or at least its ability to run.
That was yesterday.
Today Windows 8 told me it needed to update my Nvidia drivers and being a total idiot I did, and it failed to complete for some reason.
Things were looking a little odd to me so I rebooted, now the Octane demo is working fine, Windows is telling me to update my Nvidia drivers and so is Nvidia's control panel thingy.
Is this normal stuff?
Which is right, and which if any should I blindly obey?

Is this something that happens often? And if so what do I do to keep from messing stuff up now?

You are being fed automatic updates by Microsoft.
New drivers can mess up the running of Octane versions. On top of that it might have been a screwed up cross pollinated install by the sounds of it. Best to stick with the version Otoy build against. To make sure everything is all present and correct it might be an idea to uninstall your driver and reinstall the Octane correct one using Nvidias' clean install option
There is a setting in Window.s 7 to turn those auto driver updates off and just get the security updates.
Windows 8 is probably much the same. Sorry I'm not I front of a Windows machine at the moment to give you directions to it...perhaps someone else who is passing can do that for you. :geek:
