#3. Type cmd and press Enter on your keyboard to open the command prompt.
4. Copy and paste the following lines into the command prompt, one at a time, and press Enteron your keyboard after each one.
- Be sure to copy and paste these commands, rather than typing by hand, as entering the command incorrectly could cause some harm to your computer
- Paste by right-clicking and then selecting Paste
icacls "%HOMEPATH%\Dropbox" /grant "%USERNAME%":(F) /T icacls "%APPDATA%\Dropbox" /grant "%USERNAME%":(F) /T
Scroll right to see the complete command line.
If the location of the Dropbox folder does not have C:\Users\YourUser\Dropbox as its path, modify the first command to point to it. For example, if your Dropbox is in D:\Dropbox, the command would appear as:
icacls "D:\Dropbox" /grant "%USERNAME%":(F) /T
The other commands should remain unchanged. Note that, depending on the size of your Dropbox, this operation may take some time to complete. Wait for the C:\ prompt to appear again before proceeding.
#5. Restart Dropbox by opening the Start menu, selecting Program Files, and then Dropbox.
