The desktop app on Windows isn't starting up, why?

Hi rjsnow, thanks for bringing this to our attention.

Could you copy and paste the contents of that txt file in your next reply in order to see what could be causing the startup issue of the Dropbox desktop application?

This will help me to assist further!

Thanks for getting back to me.  Here is the content of the txt file:

Have you changed the username on your computer on the new machine?

I am not sure.  I just had Geek Squad transfer everything to this one, so I didn't think I did.  Is there a way to find out?  I still have my old computer.

If you're not on a Dropbox Basic plan with more than 3 devices connected, could you try an advanced reinstall of the app using the steps in this link?

I could not find Dropbox in any of the files you mentioned.  I am not sure it is on my computer at all.  I did unistall my app.  I checked for the files in the instructions and could not find any of them, so I restarted my computer and reinstalled the app, but when I clicked on open after the install, I got the same message that I could not open Dropbox with the same issue showing as originally.

Hey rjsnow, sorry to hear about that!

Often, the antivirus (not only your firewall) or security software on your computer will block Dropbox from completing the install or startup process. To see if this is the issue, follow these steps:

Temporarily disable any antivirus or security programs on your computer. Reinstall the Dropbox application using our offline installer.

If you still get the same result let me know. Thanks!

Hi Megan,

My computer no longer gets the error message!  When I go to my app, it does show a file Dropbox file.  When I click on it, it has two items - (1) The Dropbox app logo and (2) Dropbox Website.  When I click on the app logo, I get a small circle on my screen for a few seconds, and then it goes away and nothing happens.  When I click on Dropbox Website, the Dropbox site does open.  Is this what is supposed to happen?

Hey rjsnow, good thing that the error is gone!
Now onto the app itself. It shouldn't behave like that. 
Can you clarify if you're clicking on the little Dropbox icon on your taskbar, next to your WiFi?
Also, it might sound trivial but have you tried restarting your device at all?

Hi Megan,

I do not have any icon near my Wi-Fi symbol.  I have to click on my start icon and go to all apps and find Dropbox in there.  I did pin the Dropbox icon to my task bar, but when I click that, nothing happens.  Also, I have restarted my device since I installed it.
