Things I tried:
我尝试过的事情：
Added this at the end of php.ini:
[PHP_COM_DOTNET] extension=php_com_dotnet.dllAdded
extension=php_com_dotnet.dllin [PHP] section of php.iniRebooted IIS and also rebooted server itself.
Downgraded PHP to 5.3.27
在 php.ini 的末尾添加了这个：
[PHP_COM_DOTNET] extension=php_com_dotnet.dllextension=php_com_dotnet.dll在 php.ini 的 [PHP] 部分添加重新启动 IIS 并重新启动服务器本身。
将 PHP 降级到 5.3.27
Nothing seems to work. How do I fix this error?

In addition to adding
除了添加
[PHP_COM_DOTNET]
extension=php_com_dotnet.dll
to your php.inifile, you have to tell PHP where to look for the extension, and to enable extensions.
对于您的php.ini文件，您必须告诉 PHP 在哪里查找扩展名，并启用扩展名。
To tell PHP where to look for extensions on Windows just uncomment (remove the leading ;) following line:
要告诉 PHP 在哪里查找 Windows 上的扩展，只需取消注释（删除前导;）以下行：
extension_dir = "ext"
To enable extensions set the enable flag to On:
要启用扩展，请将启用标志设置为开：
enable_dl = On
