Move TB profile backup (hy4v3mvb.default-esr) to new computer

This REALLY shouldn't be this hard. Created a TB profile backup (see subject) from my LAPTOP. Copied it to c:\users\username\appdata\roaming\thunderbird\profiles on DESKTOP. Trying to open TB, I get error: Your Thunderbird profile cannot be loaded. It may be missing or inaccessible

Must be something I'm doing wrong. Been on the interweb for 2 hours trying to get this accomplished. Tried everything I could find. Unsuccessful. Can someone help?

As an aside, c:\users\username\appdata\roaming\thunderbird entry is MISSING from my laptop. Can't find the profile directory. TB opens fine on the laptop, so profiles directory is available to TB, but NOT to me. Where would the profile directory be stored on the LAPTOP?

Yea. Think I installed using UNIGETUI. That may have made things difficult. Downloaded from Mozilla and reinstalled. Getting pretty familiar with TB setup settings. Have set it up about 5 times in the last week. Thanks.

If you installed from Microsoft, it will be in a different place. You should use thunderbird.net for the download.
