Trouble Updating Firmware Version 1.0.8 [Windows]for RF 24-70mm f/2.8 Lens

[out of focus]

From Canon's website, I've downloaded the most recent firmware (version 1.0.8) for the RF 24-70mm lens and have extracted the files, but each time that I've tried it, I get a message stating that Adobe Acrobat Reader can't open the .afu file.
I'm wondering if anyone has had a similar issue and if there's a way around the problem.

The .afu is not an Acrobat file.

The method I use is:

Format the memory card.
Relocate the RF023108.auf file to the root directory of the memory card.
Mount the lens.
Set the camera mode to M (Manual)
Go in the menu and update the firmware.

After it has finished:

Double check the firmware version.
Turn the camera off.
Remove the battery.
Wait 10 seconds before reinserting the battery and turning back on.
Format the memory card.

Thank you for your reply, Dean. That's why I'm confused as to why I get the message that I do regarding Acrobat. After I downloaded the most recent version of the firmware, I'm given no option to open the .auf file any other way, and I've tried downloading it on multiple occasions, all with the same result.

 

[Dean Wilson]

The .auf file is NOT MEANT to be opened.


In the zip file you downloaded from Canon there is a File "RF023108.afu" and a Folder "update-procedures-pdf".

Open the Folder called "update-procedures-pdf". In that folder is a file called "lens-firmwareupdate-en.pdf"

Open the "lens-firmwareupdate-en.pdf" file and beginning on page 2 are the complete instructions.

I had read the instructions that were downloaded, and I never had this issue when I updated the firmware for the camera body, but the problem in trying to update the firmware for the lens lies with what gets downloaded.
All that gets downloaded is the following, and I can't seem to do anything with the RF023108.afu so that it's not identified as a .pdf:

It appears that you have the software file "associated with" Adobe.

Give me a couple minutes...

UPDATE:

The ONLY way I have discovered how to disassociate the .afu file is to uninstall Adobe Reader. I have tried various techniques, but this is the only way I have discovered yet that works.

There are many Readers that can open .pdf files. The one I use is Foxit PDF Reader (Free)

Thank you for your message, Dean. I think that I might end up having to uninstall it since I've also been unable to find a way to update the firmware.

I uninstalled Acrobat Reader that was creating all the trouble and updated the firmware successfully right after that. Thank you!

 

[Dean Wilson]

Remember. If you install Acrobat Reader in the future the .afu files will still be associated with it.

Yeah, I don't think that I'll be reinstalling Acrobat Reader because of this. I'm going to try something like Foxit PDF Reader and see how that does.

Hi Johnny,

Sorry to read you're having issues with the f/w update (updates always carry a certain level of anxiety without any additional snags).

Regardless of how your Windows system recognises the '*.afu' file, there is no need (or purpose) in trying to read it with your PC - the file is meant to be used by your camera to install the update to the attached lens.

Given this, as Dean suggested, have you tried just copying the '*.afu' file to the root of an SD card and following the update procedure as outlined in the pdf instructions? (i.e. Can the camera read the f/w update file?).

(I can't see why your PC system would change the 'afu' file extension, which is what the camera will look for when it carries out the update, even though Adobe Acrobat wants to treat it as an associated/ readable file).

It may be the update will work if you follow it through?

Hi Phil,

The only way this can happen is if you attempt to open the .afu file using Acrobat Reader. At that point Adobe associates the AUF extension as an Acrobat file.

Mistakes happened and the world survived. I haven't discover how to re-associate the AUF file back to the original file type, as your computer can easily reassociate it, but it needs to know what to associate it with! I never found any information on the Canon USA website (forums/support/knowledgebase).

Hi Dean,

Bear with me as I use a Mac for most stuff (and I’m lost in a sea of chaos with that much of the time), with my Windows PC reserved for gaming (the same comment applies).

Is it the case that Adobe Acrobat has renamed ‘Updatefile.afu’ to ‘Updatefile.pdf’ and it can’t be changed back? If so, .

If not, and it’s still ‘Updatefile.afu’, despite the fact that Adobe Acrobat wants to hug it on the PC, why can’t the file be copied to an SD card so the camera can use it to carry out the f/w update?

Perhaps I‘m missing something, but the good news is - dinner’s ready…

Once the computer tags an file extension as "Open With..." it remains that way until you tell to associate the file extension with a different program, that is, "Open with..." something else.

I image this is true no matter which OS you use: Windows, iOS, Linux, Unix, TRSDOS, or any other OS.

By the way....why can't I purchase Walker's Pure Butter Shortbread "Highland Cow" in the US? I'm all out!

Hi Dean,

There are many things which will forever remain an unexplained mystery to me - computers, football, the fairer sex, life…

(I try not to think about it too much).

Good luck to the OP - perhaps, if they find the answer, they’ll come back and let us all know? (One less thing to ponder).

Hi, Dean and Phil
Once I uninstalled Acrobat Reader, the file appeared as it's supposed to and I updated the firmware without any problem. I'm just going to try to use something else like Foxit PDF Reader that Dean had mentioned and see how that does for reading .pdf. Since making the change resolved the issue, I think that it's a fairly minor adjustment.

Hi Johnny,

Great to hear you got everything sorted, thank you for posting the update (your solution may help others).

Technology eh?
