Ressource.dll missing all of a sudden?
Hi at all,
every few weeks my TeamViewer (newest version, paid license) is not responding anymore. I cannot start it again because "ressource.dll" is missing?!
Reinstall works fine, but only lasts a few weeks until I have that error again.
PC is completely fine, not other problems whatsoever. Can anyone give me a hint?

Hello, I tried to use the tickt that support tells us to do. They took a long time,
the solution I found was as follows.
With a working TeamViewer program, you will copy all the files from the teamviewer folder:
it will probably be under Program files > TeamViewer. Once you copy the files, paste them into the
TeamViewer folder that is not working.

Hello @Naddel81,
This sounds very much like something unusual on your computer that currputs a TeamViewer installation string.
I'd recommend processing a full uninstallation (by deleting all TeamViewer items from the registry) and reinstall the latest version.
You'll find here how to process a full uninstallation here:

I can tell you in a few weeks since the problem shows up unregularly after a few days. longest period was 2 weeks until TV refused to start up because of a ressource.dll error.

Similar problem when Bitdefender Advanced Threat Detection inadvertently marked new another .dll as suspicious and moved it to quarantine every time it performed full scan, resolved by re-installing - fixed temporarily, marking as safe and permitted in BitDefender resolved permanently. May be worth checking antivirus settings before going too far.... Good luck.

Thank you for the update, Naddel.
@CrackedQuackNo1 this is very clever! That's an aspect that we haven't discussed yet.
Naddel, did you check if the issue might be related to the Antivirus you are using?
Maybe adding TeamViewer in the "Exceptions" of the antivirus program could help...
Let us know how this goes!

good suggestion. I do not use antivirus software. I even have windows defender disabled. that should not be the culprit.

Same procedure as every month. I am honestly considering to cancel my paid subscription. I have attached the errors.

Hi @Naddel81,
For security reasons, I had to remove the changelogs as they contain private information.

For what it is worth, I have recently begun to have the exact same issue on my Windows 10 desktop PC. Everything works fine for a few weeks and then when I try to access that system from my Linux laptop the desktop is reported as "offline." Further investigation on the desktop PC shows TV no longer running and when I try to restart I get two dialogs reporting a generic problem and then the specific "teamviewer_resource.dll is missing" message. My only recourse is to uninstall, restart, and then reinstall.
On the Windows 10 desktop PC I have defaulted to Windows Defender and am having difficulty finding the configuration page where I can white list teamviewer_resource.dll. Any suggestions as where to drill down in the Windows 10 settings to find the white list configuration?
I would think the TV developers would survey popular anti-virus packages and work with those vendors to white list all of TV's files appropriately "out of the box." When I developed Windows software for HP (now retired) that was standard procedure prior to every software release.
Thank you!

I'm facing the exact same problem on two different PCs now. This is ridiculous, a (paid!) remote access software that fails to run on the remote computer. It passes no more than a week before we have to fully reinstall. [removed per Community Guidelines]. Shameful, total disgrace.

I have server suffering the same symptoms.
Thanks for any enlightenment.

Same issue here, it's about a year now. Had to reinstall TV multiple times. I have Win Defender turned off too, no other antivirus is up. The teamviewer_resource.dll cannot be found on my PC now.
As i see this issue isn't new, i saw it on the M$ support page too since 2017??

Same issue here with Windows 10 with Bitdefender and Windows 11 with McAffee.
On both devices all files TeamviewerResource.*.dll were simply deleted. Don't know why. None of the files can be found in quarantine of BitDefender or McAffee. There are no reports in both security applications, that something was deleted, moved to quarantine or similar.

Was facing the same issue. I tried this and issue seems disappear now:
Added Teamviewer installation folder to Windows defender exclusion.
Steps:
Windows Security/Defender -> Virus and Threat Protection -> Virus and Threat Protection Settings -> Manage -> <Scroll Down till> Exclusions -> Add or Remove exclusions -> Add exclusions -> Folder -> Add TV installation folder (C:\Program Files\TeamViewer - In my case) .
That's it.. :)
But, this should be used with caution/own risk as it will keep your TV on risk.
Please try and update if issue fixed at your end..
Happy remoting.. :)

This is not a solution. After the error with missing dll, i did the copy back to the folder. 2 weeks later went missing again. Lot of files are missing. TV has only 1 purpose: when my vpn dies due network issues, i can restart it over TV. But when my vpn dies, TV fails to work. Pretty much useless.
