i have recently done a format on my C drive leaving my D drive.And in that case i had DOWNOAD ACCERALATOR PLUS(DAP) but that vanished off as i had format.But now i have downloaded DAP again.and then usin DAP i have downloaded QUINTESSENTIAL PLAYER.But after running the setup FILE of QUINTESSENTIAL PLAYER - IT started a commant promt and then closed too.Now it no more a set up file ..

GOING back i wanna tell u that i had many of the softwares to be downloaded when i didnt format my hardisk C . and there were mane incompleted software which saves in DAP .I also want to download those softwares.Ok, retype and rephrase your question, and then I can help.

By the way, where did you get DAP from?I have downloaded DAP from speedbit .com. DAP downloads software
too fast then simple download.
whenever we click to download then DAP does by itself ..

so i have downloaded QUINTESSENTIAL PLAYER...

Which is downloaded in a FOLDER which is created by DAP itself .

the Que is that the player which i have downloaded should start installing
wheras it is opening with MS DOS.... I have downloaded DAP from speedbit .com. DAP downloads software
too fast then simple download.

so i have downloaded QUINTESSENTIAL PLAYER...

the Que is that the player which i have downloaded should start installing
wheras it is opening with MS DOS....OK, does this happen with everything you download with DAP? If not, then it is something to do with the QUENTE... player itself.

Anyways, what happens after you download the Q Player? You said it OPENS into MS-DOS, what does it say?not it happens when i download any software.......................

well its not the case with any MP3 file


am amazed why does it happens with an installation file?The program is not written to run in DOS...
