EOS Webcam will not install EWCService.exe failed to start. Verify.....sufficient privileges

RichardZ — Sat, 11 Feb 2023 18:56:19 GMT

Windows 10, fully updated as of 2/10/23.

I borrowed some text from another thread but it describes the problem in detail..

"It flat out refuses to install. I go through all the install process, it unpacks, goes through install progress bar comes close to complete, it hangs for several minutes and then pops up with

EOS Webcam Utility

! Service EWCService' (EWCService.EXE) failed to start. Verify

That you have sufficient privileges to start system services.

Retry/Cancel

Try retry all day long and it just repeats only option is to cancel" .......which uninstalls the package.

I am administrator and right clicking and running the install as an administrator does nothing.

I have rebooted, updated the machine to the latest version available and installed GPEDIT.MSC and set privileges in it according to a web article. Still does this and it will not install.

The log that is generated is useless. The developer created an exception routine but didn't put anything in the log to say why the exception occurred.

Hello RichardZ,

What type of security/firewall are you using? This may be what's keeping the install from running properly. There are no known issues with the EOS WebCam Utility on a Windows 10 system. In fact, that's what we run in our support call centers with the software. If the issue persists, you may want to contact Microsoft or your computer manufacturer to troubleshoot the computer end.

Thanks for your response. I am using AVG, current free version, and I disabled it and had the same results with the install.

The machine having the problems is a Toshiba Satellite C55B, running Win 10 Home edition 22h2.

The BIOS is Toshiba 5.0

I sent the log to my son who manages (a group manager) IT support teams at a major insurance company. He looked at the log and was not impressed since it apparently does not offer any information regarding the cause of the fatal error. He is an acknowledged expert in his field in the insurance industry and regularly wins awards and accolades for his technical expertise trouble shooting software, computers, servers and network issues. The statement about the log was not made lightly.

Unless you have some other thoughts I will discard the idea of using this on the machine. We take it when we travel and it seemed like a neat addition to the machine. Thank you again.

Richard

I do not think your Toshiba Satellite C55B meets the minimum hardware and operating system requirements to run the latest Canon applications. Upgraded Operating Systems are known to be incompatible. Your screen resolution may not meet the minimum requirements, either.

You’re also running a Windows 8.1 machine that has been upgraded to Windows 10. Upgraded Operating Systems do not meet the minimum Canon specs.

Not sure where you are getting your info but this machine had Win 10 on it when I bought it new. I don't think the Canon software can look back and say...oh, this machine probably had Win 8.1 on it...particularly since it did not. Thanks for your input.

Features:

• Works with more of your favorite streaming apps

• Compatible with Windows 10 & Windows 11

This is where I am getting my information from….

https://laptoping.com/specs/product/toshiba-satellite-c55-b5302/

Is that the correct laptop that you have? The laptop was being sold with a free upgrade to Windows 10 back in 2014. I do not doubt that it was running Windows 10 when you bought.

However, there is a major hardware difference under the hood between a machine that runs Windows 10 and those that ran all previous versions. It is not a problem for a spreadsheet application to run on an upgraded Windows 10 OS. All a spreadsheet does is process data and R/W to memory.

The problems arise when the application interacts with the computer’s hardware like USB ports and such. While the desktop may look like Windows 10, Windows 8 is still what is running under the hood because of the hardware.

I have discovered that the Installer service is set to manual and is greyed out so that I cannot change it to automatic. I suspect that unless the install package starts that service it cannot install. I have found out how to get around this problem but, before I do, I thought I would ask if you had any information in regards to this thought......

I have been having the same problem. I have been able to download other stuff. I specifically bought my camera for using this feature. I made sure my brand new computer has all the specks it asks for. I am getting really frustrated and trying to find different off brand program to download that will work instead.

RichardZ — Sun, 19 Feb 2023 15:27:24 GMT

There is some nuance that the install process is missing. I actually ran the install until the error message popped up and then went into services and EWCService was actually installed, and started, (with Automatic setting) so this is a false error message. Something else is going on. I confirmed this by running the EWC Utility, since the shortcut remains until you cancel the install, and was able to see it as a camera option in Windows camera. However it would not feed video....I suspect the install is not entirely done. I powered down the machine using the long press on the power button (to exit without the uninstall process running).. When I restarted the laptop the service was still installed. The EWC still showed as a camera option but it would not feed video....again it was an incomplete install. I am at a loss as to get it working. It should. I am still pondering but may not have any more avenues to pursue.

BTW, thanks for posting. This confirms to me that it isn't an "old" machine issue since my laptop also meets the minimums as stated by Canon. Can I ask what machine and operating system you are having problems on? And, does your new machine have a built in camera?

I have the same error. I have an old motherboard with a q9550 processor, 1050ti graphics card and 8gb of ram. Could this be a problem? Or is the problem because I'm from Russia?))) I hope it's not so 🙂 Tomorrow I'll try to install the software on another computer, I hope the situation will change. I wish you all the best! 🙂

No luck so far. Haven't done much more. One of my posts in this thread explains that I believe the error is a bogus message since I could see that the EWCservice.exe had actually installed and started. Too much else to do rather than chasing this....

I appreciate your diligence in reporting and following up on this problem. I've encountered the same error—though, in my case, the error message was a correct report; i.e., the service had not, in fact, started successfully. Since it sounds like the error message was incorrect report for you, I've created a new thread for my scenario. As they're so closely related, however, I wanted to make you (and anyone else with this error) aware of that thread as well. In the meanwhile, I hope you've had more luck than me in getting this resolved.

Waddizzle, it is really presumptuous to suggest that because a machine was originally designed to support Windows 8 that,

the specific machine previously had Windows 8.1 installed on it, or
the hardware isn't supported by Canon's software.

There were a lot of very high-end machines on the market that well-surpassed Windows 8 minimum hardware requirements, and easily supported Windows 10's own hardware requirements upon its release.

(Source: I used to work in Windows support.)

If there are, in fact, such limitations, then Canon's minimum hardware requirements should clearly state what those specific limitations are. Some of those requirements may happen to match with the minimum hardware requirements for Windows 10, but that doesn't necessarily preclude machines that were capable of running Windows 8.1.

Given this, your response comes across as a way of shutting down a legitimate line of inquiry because you don't otherwise know what the problem is. That's not useful, and especially when other contributors have confirmed that they are experiencing this on what sounds like much more recent hardware.

Try the following.

When the error dialog pops up...

Windows+R key

Enter "services.msc" in the run dialog, press ok

Scroll to service EWCService. Right-click on it and select properties. Change start up type to disabled. Now select stop service. Once the service stops, press the re-try button on the error dialog. The install should complete. Change the service start back to Automatic, save. Restart the machine and test.

I have not tested this myself.

**Edit, there is a difference between the v1 and v2.0 versions of the software. (Device driver vs. application) v1 did not work when the EOS Utility was active. I'd exit this app from the system tray (temporarily) while I tested v2.0.

I’m just the messenger. I apologize for explaining why it will never work with an upgraded Win10 OS from Windows 7, 8, or 8.1.

Thanks for the suggestion. It will be later today but I will give it a shot.

Tried this and still get the same error. So, I tried to manually start the service and no matter what state (automatic, manual, automatic (with delayed start) I could not manually start it. Got a 1053 error, "The service did not respond to the start or control request in a timely fashion". So based on Googling I ran an sfc /scannow but no errors were found. The next step will be to edit the timeout in the Registry and see if it is set properly. At a loss beyond that. I see that a couple of others are now reporting the same problem with much newer machines.
