I am the system admin helping the accounting guy with his peachtree software. I just installed Peachtree premium 2009 on his computer as a separate install rather than an upgrade by instructions from tech support because the upgrade kept failing. The data converted and it seems to be working fine now. He still has version 2006 and 2003 installed on the computer and I would like to remove them but he is paranoid about any futher changes to his computer. I think it might cause problems to leave the old versions there. What do you think I should do?
