Rollback from v15 to v14 under Win 10

RStocker

Hello,

I need to downgrade or rollback the TeamViewer installation on a Windows 10 system which was automatically updated to v15 this past January because I still need to connect to that system with v14. I can uninstall the existing installation. However, the current installer (TeamViewer_setup.exe) will only install v15. I've tried to get at the older v14 (setup or MSI) through the management console with no success. What now? Isn't there some way I can just simply get at and download the MSI in order to revert that system?

Thank you for any help!
