When I try to start up Thunderbird, I get an error message that says:

Error: Platform version '38.4.0' is not compatible with minVersion >= 38.3.0 maxVersion <=38.3.0

The file version listed is 38.3.0.5749 and the product version is 38.3.0; last updated on 10/5, apparently.

Chosen solution

just reinstall, your mail and setting will be unaffected and whatever file is corrupt will hopefully be replaced.

It looks like the error is from an add-on not compatible with Thunderbird 38.4.0. Try to start Thunderbird in safe mode. https://support.mozilla.org/en-US/kb/safe-mode-thunderbird

Unfortunately, Thunderbird does not launch in safe mode either - I get the same result. I try to open it as your linked article says, by holding the shift key down.
