where the following are suggested:

– install Update for Windows 7 (KB2533623) from Microsoft:

And an extra tip, in case you after the installation, when you try to connect via a meeting URL, you see this dialog:

then try enabling TLS 1.1 & 1.2 at your browser (e.g. was told Chrome on Win7 had then both off). See how to do this for various browsers at: https://knowledge.digicert.com/generalinformation/INFO3299.html

Regarding TLS 1.1 though, mind you that it is considered insecure – so you might decide to skip enabling it (and try just enabling TLS 1.2) unless you can’t find some other solution. Quoting recent article on TLS 1.0 and 1.1 protocols:

Microsoft announced today that it will delay disabling support for the insecure Transport Layer Security (TLS) 1.0 and 1.1 protocols from Microsoft web browsers because of the current global situation until the second half of 2020, with an estimated time of roll out during July. “For the new Microsoft Edge (based on Chromium), TLS 1.0 and 1.1 are currently planned to be disabled by default no sooner than Microsoft Edge version 84 (currently planned for July 2020),” Kyle Pflug, Microsoft Edge Developer Experience Principal PM Lead, said. “For all supported versions of Internet Explorer 11 and Microsoft Edge Legacy (EdgeHTML-based), TLS 1.0 and TLS 1.1 will be disabled by default as of September 8, 2020.” https://www.bleepingcomputer.com/news/security/microsoft-delays-disabling-insecure-tls-in-browsers-until-july/
