用DS开发PCI驱动，在安装时出现问题，请指教

我用DS开发PCI驱动：一开始写的一个版本可以安装，且功能正常；随后又用ds的wizard生成了一个新的针对该PCI板的驱动，此时安装新驱动时出现错误。

错误：
An error occurred during the installation of the device
The name is already in use as either a service name or a service display name.

两个版本的inf文件

;--------- Strings Section ---------------------------------------------------

[Strings]
ProviderName=\"Your Company Name here\"
MfgName=\"Name of HW Manufacturer here\"
DeviceDesc=\"Description of Device here\"
;下面这两行得改一改
DeviceClassName=\"my pci class\"
SvcDesc=\"my pci service\"

否则就会报你这样的错。

我试试先。

Wonderful, it\'s working now!
But, would you be kind enough to explain it or provide some document about INF?

Thanks a lot!
