We want to help you, and we probably CAN help you, get ScannerCast running. It's running on hundreds of machines. I've, personally, never seen a Windows systems (from Win2K and later) that it doesn't run on.
The problem is that saying "it doesn't work" really doesn't give us any clues that might help us to help you solve the problem. Just saying "it fails to launch" is a bit like posting a question that reads "Please help me, my car doesn't work" -- WHAT doesn't work? Will it start? Will it run for a while? Is the battery charged? Does the engine turn-over? Is it getting gas? Is it getting spark?
It's the same with ScannerCast: What EXACTLY happens and when? What are the symptoms. What type of scanner? What type of sound card? What do the messages say? What does it say in the DETAILS tab of the messages that are displayed?
Also, in this case, immediately after the problem -- and before starting ScannerCast again -- there should be a file named scannercast_ERROR.log created in the same directory as ScannerCast.exe -- If that's the case, please post the complete contents of this file.
Also, knowing which version of ScannerCast you're having a problem with would be very useful. On the folder into which you've installed ScannerCast, right-click on ScannerCast.exe and select "Properties", and tell us the Product Version that's displayed on the "Details" tab.
