for example, when try installing the video driver ( "2-Win7Vista15177" on my eMachines e725, Windows 7 ) , I get two error messages. 1st - <system cannot find the file specified > , than I press ok, and the second message, with the red icon alert - <Unable to open the self-extracting executable file. The file is locked or in use by another process. The install will terminate.>
then I tried to install the audio driver. - The program may not have installed correctly. And the options next..as in all win 7 OC's. And some other software with such kind of messages. Otherrs work well. These, copied to C , work well to.. I remeber same issue, when was using XP SP3 of a friend..and had the same situation.
