thank you ed
but i think the whole operating system could be compromised(windows vista home premium)
actually these are drivers for a printer scanner fax copier from brother...but nothing is helping.....
I ran it as an Administrator..but either i get the message above or this error(difx driver package install error=1610154566.the exe's are 295-INST-A.EXE and 375-USB2KXPVISTA-32-A-US.EXE downloaded from Brother site...I don't know.Maybe i shall re install
the all operating system....this computer was my brothers...and he could have been compromised with today's viruses..I thank you for taking the time to answer me....
