Cruzer SDC236-016G problem

I have used it on all types of computer and operating systems, but it would not work on a Dell inspiron Windows7.   It has worked on Windows 7 on my computers.  It still working on other computers that have Windows 7.  It show that it does not have the driver in the Dell.  The cruzer automatically put the driver in when you first plug it in.  I tried downloading drivers and using them it did not work.

I am puzzled.

Do you have any of these programs running on the Dell?
