[FIXED] Dropbox won't start when Boxifer is installed


I have a Windows 7 computer where Dropbox works normally until Boxifier is installed. With Boxifier installed, even if it’s not running, Dropbox won’t open. I can get Dropbox to launch by renaming the .exe to “Dropbox - Copy.exe”, but then Boxifier gives the error “Boxifier Core is not running”. Uninstalling Boxifier allows Dropbox to launch normally again.

Additional symptoms: When Boxifer is installed, launching Dropbox creates one process in Task Manager that uses about 3 MB of RAM. The system tray icon does not show, no syncing happens, and Boxifier says “Waiting for Dropbox…” Normally, Dropbox will create three processes, two of which use about 2 MB RAM and one that uses 100-150 MB RAM.

I’m on Boxifier 1.6.16, Dropbox 40.4.46, and my antivirus is AV Defender by Bitdefender.
I have uninstalled Dropbox and Boxifier and reinstalled both. I also tried Dropbox version 39, but got the same result. Do I need to be on an older version of Dropbox?

Any help or troubleshooting ideas are greatly appreciated!

Best Regards,


Hi Chad,

Could you please try this version and let me know if it makes any difference?
