My husband has a Dell Inspiron Zino HD that had the same problem.  I went to www.delldock.com.  They have a free download for dell dock.  I did the download and it fixed this computer.  No more Dell Dock errors.  It's worth a try and it is free.  Good luck.:emotion-2:
  Hi, I cannot tell you how much time and effort I put into trying to solve this but it seems impossible. I bought an Inspiron 1525 laptop just 4 months ago and was quite happy with the Dell Dock feature as it made life easier when working with Office. That was until the bleeding Dell Dock went bananas and doesn't run anymore. It's quite annoying because every time I turn on the computer I get the error message about 5 times in a row! And when I try sending the error report I get another error!!!! How frustrating...:emotion-12: I tried getting rid of it and reinstalling but it won't work neither. Called Dell and they told me they do not offer support for this and I'd need to pay ££ to get help. Now....this is ridiculous! I did not ask for the software, "Dell geniuses" decided to install this piece of faulty software in my machine and now refuses to offer help!!! Shame on you Dell!! Well, if you are a user and is having the same nightmare, please let me know if you found a solution, I'll be very grateful and might light you a candle.:emotion-5: :emotion-22::emotion-48:
"Dell Dock has stopped working" - Very annoying!
