TeamViewer Again
« on: December 17, 2021, 08:49:09 pm »
I noticed that I had not received any TeamViewer updates in a while.  I checked.  The version that I had was 15.22.3.  I run UCheck every Friday before I backup my computers.  Both are running Windows 11 Pro x64, 21H2, fully updated.

I launched TeamViewer and "Check for Updates" and found that the current version was 15.25.6.  I updated to that version via TeamViewer.

There have been issues in the past with TeamViewer changing its update protocols so that the UCheck "scraper" does not find them.  I suspect that has happened again.

Submitted for your information.  Have a great weekend.

Hi Phil,

At first sight, we didn't spot any issue on our side.
Could you please attach a scan report before you manually updated TeamViewer ?

Thanks and have a nice week-end too.

Regards.

Curson,

I have attached the scan report from the previous Friday.  I looked at it myself, and I saw that I had the 32-bit version of TeamViewer installed rather than the 64-bit version.  I uninstalled the 32-bit version and installed the 64-bit version.  If that was/is the issue, you can ignore my post and I apologize for wasting your time.

Have a great weekend.

Hi Phil,

Thanks a lot.
No, the 32-bit version being installed should not have caused the issue. We will investigate this and come back to you as soon as possible.

Have a nice week-end too.

Regards.

Hi,
It seems to be an issue with TeamViewer CDN.
In North America, where our server is located, the version on their website is old. And UCheck relies on that (indirectly).
We have contacted them, hopefully they are willing to fix that soon.

EDIT: They answered this will be fixed soon, UCheck should pick up the correct version once they deploy their fix.
I'll try to confirm by checking from time to time.

Thanks for the feedback

@Tigzy

Was notified by UCheck that there was a TeamViewer update.  UCheck was in batch mode (administrator), and the update appeared to install normally.  I launched TeamViewer and it said it was still the previous version.  I ran UCheck again, and this time it told me to uninstall my 64-bit TeamViewer and install it again.  I did not.  I updated TeamViewer successfully via TeamViewer.  Something strange is going on.  Scan logs and screen snips attached.

Thank you and Merry Christmas.
