Updating wireless card driver

Specifically, here is what happens when I run the latest driver download.  I had downloaded it to my Desktop.  When I double-click it, it asks if I want to run the file.  I click ‘Run’.  A window appears identifying the driver and the computers and operating systems it is compatible with.  Mine are on their, so I click ‘Continue’.  I select the folder to unzip it as c:\Dell\Drivers\R107434 and I click ‘ok’.  It unzips the files and says that it was completed successfully.  I click ‘ok’ and then a window comes up that has a heading of “16 bit MS-DOS Subsystem”.  The text in the window reads:

C:\DOCUM~1\Dad\APPLIC~1\SMBIOSSP.exe

C:WINDOWS\SYSTEM32\AUTOEXEC.NT.  The system file is not suitable for running MS-DOS and Microsoft Windows applications.  Choose ‘close’ to terminate the application.

 When I click on ‘close’, another window pops up with a heading of “iProInst”.  The text in the window reads:

 ERROR – This installer does not support installation on this computer.

Any suggestions as to how to get it to load properly?   I have rolled back to my previous driver for the time being.
