Failed to add certificate to Third-Party Root Certification Authorities Store

The Twingate Windows Client fails to install. In the application log, I see two errors. Failed to verify the assembly signature reason Untrusted Root. Failed to add certificate to Third-Party Certification Authorities store with error access is denied. Can someone tell me how to fix or the name of the certificate so I can import from a different computer with the client already installed?


Hi Boundless,

Can you confirm the user doing the install was an Administrator on that machine? Access being denied suggests there might not be the necessary permissions to update the certificate store on that machine.

As well are you using the EXE or the MSI installer?



Yes, the user is an administrator. I tried both the EXE and MSI installer.
