It probably not the problem, but the Wxp->x86 is not the right folder for Windows 2003. You should use the wnet folder.

I think that's the expected behavior, no? Windows should tell you that you have a newer driver already installed.

  Hi Gal,
     I don't think I install driver from wrong folder and please have a look on the following mapping tables.

We would like to close this bug
- A workaround for downgrade should be to uninstall first
- We try to avoid non-urgent 2003 work
Any objection?
Is it really a regression?

Hi All,
   If I did this "Not search and install driver manually -> folder -> Wxp -> x86",it worked well.
   Besides,I could get the same error to comments0 where using "search for the best driver in these locations"...
   Anyway,the search option doesn't work properly for this driver in my opinion,it should be a shortcoming while user want to install driver by this way.
   Any issues please let me know.Thanks.

Best Regards,
Min

The "Search for the best driver in these locations" should not be used to search for a driver under a directory tree that contains drivers for multiple OSes (the tree layout that we're using).

Hi Gal,

   Could you please double check the issue before close it as Not a bug ? 
I described as the following on the original info,
"search for the best driver in these locations" -> folder->Wxp->x86 (59).The driver is under folder "x86" directly but not contains a directory tree.
   Any issues please let me know.

Thanks
Min

My mistake, sorry.

It seem that you can't downgrade a driver using the "Search for the best driver in these locations" option because the newer (and installed) driver will be selected the as "best" driver.

So if want to force installation of a you should use the "Don't search" option and the "Have Disk" button to select the folder of the older driver. This method will allow you to install an older driver on a system that already have a driver installed.
