驱动程序安装问题 [复制链接]

我的板子在第一次接电脑时显示成功安装驱动程序（COM5），但是后来几次插上去之后电脑都没反应，用IAR下载程序就报错Thu Oct 25, 2012 12:52:31: Fatal error: Failed to initialize.  Check if hardware is connected. Check if drivers are installed. Try to restart the computer. Tools using the parallel port are not supported on Windows Vista   
求大神指导啊
