我的服务器上有MS Office。
如何确定服务器上安装的是Office 2013的32位版本还是64位版本？
我需要使用C＃代码获取此信息。
关于获取32位或64位版本的Office 2013 C＃代码的方法是：
private Nullable<bool> IsOffice64Bit(string RegistryPrefix, string OfficeVersionNo)
{
Nullable<bool> isOffice64Bit = null;
string Bitness = GetRegKey64(HKEY_LOCAL_MACHINE, RegistryPrefix + OfficeVersionNo + "\\Outlook", "Bitness");
if (Bitness == "x86")
isOffice64Bit = false;
else if ((Bitness == "x64"))
isOffice64Bit = true;
return isOffice64Bit;
}
调用示例：
Nullable<bool> isOffice64Bit = IsOffice64Bit("SOFTWARE\\Microsoft\\Office\\", OfficeVersionNo);
if (isOffice64Bit == null)
isOffice64Bit = IsOffice64Bit("SOFTWARE\\Wow6432Node\\Microsoft\\Office\\", OfficeVersionNo);
if (isOffice64Bit.HasValue && isOffice64Bit.Value)
InstalledOfficeVersion += " (64 bit)";
else if (isOffice64Bit.HasValue && !isOffice64Bit.Value)
InstalledOfficeVersion += " (32 bit)";
else
{
InstalledOfficeVersion += " (Unknown bit)";
}
