New Install - Critical Error when installing Garmin software

[mdtenor22]

Hello,

I posted about this on Discord before seeing that you have a support forum.

I am a new customer doing a first time install.  When completing the first step, I get a "Critical Error has Occurred". I saw some advice in the Discord to try the standalone Garmin install rather than using the TDS manager, so I tried that. Same error.  I've tried to attach the log file, but can't, so I'll paste it below, but it doesn't really mean anything to me. 

I rebooted my computer and made sure nothing else was running. Tried as administrator. No anti-virus software other than Windows Defender.

I should also mention that I disabled Windows Defender's Anti-virus protection and tried again. Same result.

Hello,

As you have posted on Discord, we will continue the discussion there, as it is faster. There is no need to post the same question in more than one place, as it does not help in tech support.
