Finally, after 6 hours of spinning my head to install Dell bluetooth 355 on Dell Inspiron 1420 with Vista Home... I am able to install it... yay - what a relief..

 

Okay, here goes;

 

Download the updated drivers from http:///support.dell.com site i.e. (# R140135).  Click run to extract the files.  Default extracted location is C:/dell/drivers/R140135.  Cancel the automated installation, go to /win32 and execute BTW.exe.  When it asks for the press Fn+F2 to enable the bluetooth; just cancel it; and let it complete the bluetooth software... Right click on the bluetooth icon on the System tray and enable it. 

 

It's that simple.

 

 

P.S.  I re-installed the vista OS, and was unable to install the bluetooth device as it was hanging at enable the device point.

 

I hope it helps.

 

Cheers

Usman.
