Digital Camera Software v7.1: "Could not connect to internet" on install

[pen7cmc]

Trying to install Digital Camera Software v7.1 on Windows 11 Home, fully patched.  After selecting a region, and then Easy Installation or Custom Installation, it tells me "Could not connect to internet. An Internet connection is required to install this from CD.  Check your Internet connection, and try installing again."

I can only click OK, and go no further. Clearly I am connected to the internet, and have only one internet connection from this computer.  I had to turn off anti-virus before the installation attempt as this program (dcsw-7-1-0-1-9l downloaded from Canon 27 Dec 2025) gets blocked as malware otherwise.  I also turned off the firewall. Selecting a different region results in the same error.  Running as administrator results in the same error.  No luck.

Any ideas?  Thank you for any assistance.

Digital Camera Software v7.1 is not supported on the Windows 11 platform.  The supported application is Image Transfer Utility,

I'm having the same issue ...  While I understand Digital Camera Software v7.1 is not officially supported on Windows 11, it seems odd that the install can be launched and only several steps later does it report "Could not connect to internet. An Internet connection is required to install this from CD.  Check your Internet connection, and try installing again."  Hopefully we can get someone from Canon Support to provide an answer to this post ...

Installers are written by Microsoft.  The default installation dialog is just a plain box.  Developers can customize the dialog window.  All developers have to do is tell the Installer the name of the app file and where to find it.

So, yes, the Installer can be launched.  It’s built into the OS.  The install failed when it came time to retrieve the app file and install it on your OS.

Something just occurred to me.  The installer could be attempting a web install.  Meaning the app you downloaded is not the actual application.  The actual application is saved somewhere on the web. 

The camera is no longer supported, so the application might not still be available.  Web installer apps tend to be smallish files, just a couple of MB.  The actual application could be a couple hundred MB, or far more. 

The message might be saying something else, that it tried to connect with the download and could not find it. !!!

A while ago, some Canon installers came with a checkbox on the installers splash screen that allowed you to disable checking for a newer version of the software on Canon servers.  If available in this install, you can try that.  If that's not present, then its not an option for you,  Since the software is from 2016, it may not run or install under W11 unfortunately.

Understood but, I downloaded the software installer from the section of the Canon support site specifically for the SX620 HS camera.  So, I would expect that if the software itself is no longer available for download they would have removed the ability to download the installer.  Anyway, I'd still like to hear from Canon on this matter.

Here’s another thought.  Do you have any antivirus software enabled?
