EOS utility does not start

paulogcarvalho — Thu, 09 Jul 2015 11:45:25 GMT

Running under W7, EOS Utility does not start anymore. Worked properly for a few monthes. Previously had some problems with wifi connection, corrected after unistalling and installing again. Now it wont start anymore (after a W7 update???) . Works fine in another computer running W7. Any suggestions?

Have you tried a "system restore", using a restore point when it worked. You could also try uninstalling the windows update you think may have caused the problem.

Yes.

Uninstall it and reinstall it, agin.

Did you do any other upgrades or additions to the computer recently? Anything?

EOS utility is initiated when windows starts up. When the 'link' is broken or corrupted the utility can not 'sense' the presence of the connected camera.

Assuming that you have the original software discs, uninstall EOS Utility from the control panel, reboot, and re-install the program. Otherwise, download the EOS Digital Solution Disc Software from Canon, supply your camera's serial number (gleaned from a pictures exif) and reinstall. Once installed update to its latest version.

Hope this helps.

Thanks to all. The problem was not a W7 update, but AVG 2015 antivirus. Windows restore function was blocked by the antivirus. When antivirus was removed to allow Windows Restore to work probperly, EOS utility poped up and worked fine. Now I have to stop antivirus when using EOS utility. I will notify the AV maker to find a solution.

PS: With the nice help of AVG support, I have created some exceptions (files that are not checked by AVG) and included the EOS Utility in this exception list. It is now working OK!

EOS Utility stopped working after AVG 2015 update (I have Windows 7 64 bits but I believe this applies for all OS).
I mean, when you try to run from Windows shortcut a message "application already running" appears, or when you try to run from the import windows after connecting the camera EOS doesn´t lunch.
It is related to AVG antivirus.
You can Disable temporarily protection or creating an exception.
I´ve created the exception as follows:
In AVG go to Options-> Advanced Configuration->Exceptions and create a new exception to the application C:\Program Files (x86)\Canon\EOS Utility\EU2\EOS Utility 2.exe for Identity Protection.

Confirmed that EOS Utiliy 2 is working without protecyion

Glad you're up and running.

I always...ALWAYS...disable my anti-virus program when using Windows system restore. I also create a full Windows OS Image backup every month after getting our monthly microsoft updates. That way if all else fails fixing any camera software issue, I can easily restore my OS (and camera software & programs) back to how it was before disaster hit. Sometimes windows system restore will fail for some reason or the other, most times from anti-virus protection being active. I cannot stress enough, the importance of an OS (operating system) Full image backup.

My EOS Utility, both 2 and 3, works when I disable AVG. But exclusion of the .exe or the entire EOS Utility folder do not help. So now I am looking for some other AniVirus. Any recommendations? Until now I have been satisfied with AVG.

Have Win 7 and Win 8.

I use Avast, it's free, and it does'nt hamper any of my Canon software. I'm surprised AVG would do that.

Are you saying you have EOS Utility 2 & 3 installed on the same Pc???

Re: EOS utility does not start

mad_marten — Fri, 10 Jul 2015 12:49:01 GMT

Yes, when I downloaded EOS Utility from Canon support pages i got new releases of 2 and 3 and both are running (with AVG disabled) on the same computer.

The thought occurred to me that having both installed may cause conflict. Is there a reason you need both installed? When any of my programs are updated, I usually either uninstall the older version, or the new version uninstalls the previous version when installing the newer version.

mad_marten — Fri, 10 Jul 2015 13:05:30 GMT

I had no choice. Both came with the download. But the ver. 3 does not recognize my 5D Mk II, but the Mk III works vitth ver. 3.

No, NO! When you install Version 3, it automatically installs Version 2, if you don't have it installed already. If you then try to use Version 3 on a camera that it doesn't support, it automatically fails over to Version 2. So you do want both versions installed. Just as you may want both Version 3 and Version 4 of DPP installed (although DPP lacks the automatic failover feature).

Hi,

I had the same problem and mailed Canon support - no answer yet - and then came across your solution. It worked for me.

But one important question.....what has Windows System Restore got to do with EOS utility? Do you know if AVG disable system restore all the time or is it only related to the EOS utilty? I would hate it if AVG is compromising my system automatic store points since I have already had store points that were infected.

Thanks a lot!

HI,

As far as I know, W7 Restore has no direct connection with EOS Utility failure.

I believe AVG will allways prevent a succesfull Restore, as it blocks changes in W7Registy.

I came to the solution by chance. As some users suggested, I wondered if a W7 update was the cause of the EOS Utility failure to start. So I was trying to restore W7 to a state before this failure. But AVG did not allowed me to a succesful restore W7, as AVG should be inactive when Restore was starting W7 in the version previous to the failure. To get to this point I had to uninstall AVG.

I believe (but I am not sure) that the exceptions are kept by AVG when the antivirus is updated or a new virus list is published.
