I have this problem also.

I just did a clean install of Windows 8 Pro, 32 bit.

Installed SpeedFan 4.47 with no problems. When I run SpeedFan (even if "as administrator"), I get that error window.

There is nothing in the Windows logs about this error.

My "debug.nfo" file:

I'm having the exact same problem.

Clean install Windows 8 Pro x64 + SpeedFan 4.47. No problems installing SpeedFan. I also tried to run as administrator followed by installing SpeedFan 4.48 beta 2 but no luck.

I have an AMD GPU so I guess I can safely ignore the line "Error opening NVCPL.DLL".

Motherboard: Gigabyte GA-890GPA-UD3H
GPU: Asus EAH6850 DC/2DIS/1GD5/V2

I have the same problem.
Windows 8 Enterprise x64 (clean install) + SpeedFan 4.48 beta 2.
Motherboard P8Z77-V + Intel Core i5-3570
Debug.nfo file is the same as reported above by afie9329.
2012-11-20 07:36   
Omg, I have the same problem

Windows 8 Pro x64 + SpeedFan 4.47
2012-11-20 10:12   
I tested the latest beta on Windows 8 Pro a few days ago. I am going to build a new system right now and test it again.

thank you so muck. waiting you new vision. my cpu fan only 1200rpm .BIOS can not working for change it . 4PIN CON
2012-11-23 11:29   
I just built a new system with Windows 8 Pro 64 bit. Downloaded SpeedFan 4.47 from, ran the installer and started SpeedFan.
No issue whatsoever. Everything worked flawlessly.
Can you, please, reboot your system, uninstall SpeedFan, reboot again, download SpeedFan 4.47 and run the installer?
Please, send me a screenshot of the messages output on the installer's window.
2012-11-23 12:07   
Strangely enough, using the above steps, SpeedFan now works. I don't understand why. It's not like I did anything too different the last couple of times I tried to install it. Having seen the installer's output quite a few times I noticed it now included some lines about the SpeedFan service. I took a screenshot as requested but I'm guessing you're no longer interested in mine. I can still upload it though. Thank you for time.
2012-11-23 12:13   
Thank you afie9329. My best guess is that you previously tried to install SpeedFan without admin right. Is this possible?
2012-11-23 12:22   
The PC I run SpeedFan on is my dev machine. I always log in as admin. In fact, it's the only active account. You should also know that the first thing I do after installing Windows is disabling UAC. So no, that's not possible.

I see :-)

Hi all. I had the same issues, and try to find a solution so i went in this site but i saw no one knews how to work it. After a few attempts i solved it myself: for win8 you need to install the old 4.45 version of speedfan. I just register in this site only to help you all, i hope it works. Good luck

SpeedFan 4.48 beta 4 has just been released. This beta comes with a full installer and it should fix every issue related to Windows 8.
2014-01-27 22:56   
I've found another problem that seems directly related to this.
I'm running v4.49 (non-beta) and got this error at start up. Following the above steps to uninstall, reboot, reinstall solved the issue.
But I noticed that the problem reappeared once I switched video cards (ATI x1900XT and nVidia GTX 260). Following the steps would solve the problem, until I swapped cards again.
I hope this bit of information helps track down the underlying cause.

Same problem here, BUT:
- speedfan shows this message only on some boots - other times it work OK.
- also after displaying the message (and not starting up) when I run speedfan manually, it ALWAYS loads properly.

Could this be some issue of speedfan running too early during the boot?

reverted to 4.50, no more problems
 -- -- -- -- -- -- -- -- -- -- -- --

Same problem here ***WINDOWS 7***
- SpeedFan 4.51 on 2 systems.

SYS1: Win7 x32, fresh Windows installation
SYS2: Win7 x64, making comprehensive software updates (stable system)

- SpeedFan set to run on boot {all users\Startup} folder. i moved it to {user1\Startup}, still getting the error.
- SpeedFan previously ran fine on both systems
- error occurrence running 100% so far on both systems
