//查询Office2007

//查询wps

RegistryKey wps = rk.OpenSubKey(@"SOFTWARE\Kingsoft\Office\6.0\common\");

//检查本机是否安装Office2003

}

//检查本机是否安装Office2007

if (f07 != null)

{

string file07 = akey.GetValue("Path").ToString();

if (File.Exists(file07 + "Excel.exe")) ifused += 2;

}

//检查本机是否安装wps

if (wps != null)

{

string filewps = akeytwo.GetValue("InstallRoot").ToString();

if (File.Exists(filewps + @"\office6\et.exe")) ifused += 4;

}

return ifused;
