I have been subscribed to UHH for a couple of years. I finally got around to joining so I could reply to your question. Windows 10 has a safety feature in that it will not allow programs to automatically install unsigned drivers. A driver is a piece of software which interfaces between the program and your hardware. An unsigned driver is one that Microsoft has not reviewed and deemed to be safe. Microsoft operating systems prior to Win 10 allowed programs to automatically install unsigned drivers, which could cause problems if the driver was poorly written or malicious in nature. Microsoft charges a fee to "sign" drivers, so companies will sometimes bypass this step. Also, older software written before Win 10, are obviously not prepared to deal with the Microsofts new procedures.

When you install software that has unsigned drivers, the installation program will run but those drivers will not be installed. This includes USB drivers. Conveniently, Win 10 does not mention that these drivers are not installed, so when your program needs them, and can't find them, things go wrong.

Microsoft did include a method to allow software to automatically install unsigned drivers, but they forgot to mention it in their documentation.

In order to enter this mode, you have to reboot your computer into a special mode. Save all your work.

Wow, Allen, thank you so much! You are much more computer literate than I am but tomorrow I will share this with my computer guru. Many thanks!!!!

There are a couple of ways to get into this mode. The one that I use I found on the web, and the text within quotes was written by this guy: Copyright 2011 - 2015 Raffael Herrmann - All Rights Reserved. I cannot find a link to share.

"First, the computer must be restarted into the so-called “options menu”. The easiest way to get there is via the “Run”-dialog, which is opened by means of the key combination Win+R. The command you have to enter, to boot into the Options menu is as follows:

1 shutdown.exe /r /o /f /t 00
Caution: This command starts the reboot process immediately! No ifs, no buts! If you still have programs open, save everything from the stuff you want to save, before you execute the command.


Because nobody likes to executes commands, he does not know, you’ll find the explanation of the individual parameters below:
• shutdown.exe – It’s a Command-Line application which is inclusive with Windows. It does various kinds of restarts and shutdowns.
• /r – means “restart”
• /o – means “the PC should start in the Option menu”
• /f – means “restart directly and close all opened programs immediately”
• /t 00 – shows the time until the restart happens (in seconds). In this case 0 seconds, which equals an immediate restart."

Your computer will reboot and you will be presented with some options. Click on "troubleshoot".

Click on "advanced options".

Click on "startup settings".

You will see a list of options, which include "disable driver signature enforcement".

Click on "restart". The computer will display a list of options.

Press "7 disable driver signature enforcement".

The computer will reboot, enter your password normally, and install your cameras software. Test.

Reboot your computer, which will put the computer back into the state of refusing to automatically install unsigned drivers, and test again.

If the software works BEFORE the reboot, but not AFTER, this means the software installs the drivers when needed (automatically) and not as part of the program. If the software works before and after the reboot, then the USB drivers are installed and things should work normally.

I hope that this information helps you solve your problem. I service a number of older pieces of equipment which require that I maintain an XP laptop. Some pieces of newer equipment require Win 7. Still others have unsigned drivers and I have to use Win 10. Computers are getting harder to deal with - not easier.

NOTE: I just found the "Browse" button and will try attaching the file which I took this information from.

Sometimes the links can be tricky, since the web page detects and defaults to your installed operating system. Try starting here:

http://www.usa.canon.com/internet/portal/us/home/support

Enter EOS 10D

When you get to the software download page, change the operating system from Windows 10 (detected) to say, Windows Vista 64, and then you can download DPP v3 and EOS Utility v2.7.3.. You may need your original install disk, since the EOS Utility is an updater, not the full package, but there are workarounds for that if you don't have the disk.

If that doesn't work for you, let me know...

Good luck!

Thanks. So if you want to experiment with device drivers if you can find them Windows Vista 64, Windows 7 64, windows 8.x 64 drivers can work for some devices. It's a matter of trial and error, but I have several obsolete and unsupported devices working just fine with Windows 10 Pro 64 that worked, but not as well with Windows 7 64.

As for the Canon software, you may need DPP v3.15 and EOS Utility v2.x. You can download that from the Canon website, and may need to select Windows XP. It may or may not work, but it may work even though it is not supported on Windows 10. It is worth a try.
