Hi there, @stephreiger138, how are you today? 

I've merged you into this current thread since you faced the same error as the OP. Can you try the steps my colleague, Walter, provided above? 

Let me know how it turns out!

[Fran29]

I have this problem too. I have already gone through the suggested tick box exercise. How do I do an advanced reinstall? Thanks for your help. (BTW I tried using the BOT and it thought I wanted to delete my Dropbox - not helpful!)

[Walter]

Hey @Fran29, sorry to hear about this.

You should be able to perform an advanced reinstall as outlined here.

Let us know if you have any other questions.
