Need to Register After Every Launch

SourceTree (v3.4.12) forces me to go through registration after every launch of the application.

I've looked at a previous post and tried their solution:
------------------------------------------------
Sourcetree should not be re-running the registration process on every re-start.

Can I check a couple of things. Where are you running Sourcetree from? It should essentially be by running %localappdata%/Sourcetree/Sourcetree.exe. 

After you run the registration process it should create a file %localappdata%/Atlassian/Sourcetree/accounts.json, this should include details, not passwords, of the registration account. Does that exist?

Additionally Sourcetree should update two settings in the %localappdata%/Atlassian/Sourcetree.exe_url{hash}/3.0.17/user.config_

AgreedToEULA = true
AgreedToEULAVersion = 20160201

If both the accounts.json and the 2 user.config settings are there, then the welcome wizard should not run again
------------------------------------------------
I've added the settings to the user.config. However, the accounts.json file does not exist for me...

Please advise with solution/next steps
