I am having a problem installing VDMSound 2.1.0 (thats the version my download file says).

I installed it from sourceforge (several times), unzip it, and double click the icon to start installation. I get the installation files unpacking and it always always always gives me an error about 2/3 of the way thru: Error opening file for writing: "C:\Program Files\VDMSound\LaunchPad.dll"

and without further explanation I am asked to abort, retry (which only repeats the little error window) or ignore. When I ignore the installation finishes but I get no computer restart prompt, as the 'vdmsound for beginners' post here mentions, just a prompt asking if I want to view the readme file (which also contains no info about this, though I have not read it thoroughly). I find no way to access VDMSound on my system- nothing on the desktop or on my start menu.

I have tried redownloading it and reinstalling it several times - and selecting all the components to install, and even installing dosbox first (FYI I am trying to play Master Of Orion 1, and got it working without any dosbox). This is really frustrating especially that I found so little on the web regarding this issue. What am I doing wrong? My OS is windows XP (SP2) and I am making sure my antivirus (mcaffee) and antispyware (webroot spysweeper) are off/disabled when I try to install.

Help me please~
