I purchased and downloaded ADDSv10 earlier this afternoon. I attempted to install it on a Win 2000 server. A DOS Window popped up for a second then disappeared. Nothing else happened. I then tried to install it on an XP Pro box just to see if it would and got the same result. I assumed the download was bad so I followed the instructions for downloading a second time. The new file was identical and so were the results. Am I missing something? Thanks in advance for your help.
