Drivers For Windows 7 64-bit Free Download

[Alana Fekety]

Provideboth 32-bit and 64-bit compilations of all kernel-mode drivers, device installation application, class installers, and co-installers. For more information, see Porting Your Driver to 64-Bit Windows.

If you are writing a device installation application, the 32-bit version must be the default version. That is, the 32-bit version should be invoked by Autorun (described in the Microsoft Windows SDK documentation), so that it starts automatically when a user inserts your distribution disk.

The 32-bit version of the application must check the value returned by UpdateDriverForPlugAndPlayDevices. If the return value is ERROR_IN_WOW64, the 32-bit application is executing on a 64-bit platform and cannot update inbox drivers. Instead, it must call CreateProcess (described in the Windows SDK documentation) to start the 64-bit version of the application. The 64-bit version can then call UpdateDriverForPlugAndPlayDevices, specifying a FullInfPath parameter that identifies the location of the 64-bit versions of all files.

This is only a half-way programming question. First of all I have a PCI-Express card and 32/64 bit drivers. The target operating system has to be a Windows 64 bit system. I read that under Vista64 all drivers have to be certified 64 bit drivers. Is this a general restriction under 64 bit operating systems and does this also apply to "XP 64" or any Linux system?

So for simplicity let's say I use a 64 bit driver for my PCIe card under Vista64 and have a bunch of 64 bit DLLs to use the cards functionality. On the other side there's a large, legacy 32 bit exe program which needs to use the PCIe device. Converting the program to 64 bit would be a really huge effort.

So what can be done to bring that 32 bit program and the 64 bit driver together? I read that mixing 32/64 bit binaries and DLLs is not possible at all but this is hard to believe for me. I'm sure you can print out a document under Vista64 from within a 32 bit app and Windows will somehow wrap this around to a 64 bit printer driver.

64-bit certification is only required under Vista; there is no certifying authority for non-Windows platforms, and I don't believe that XP or Windows Server checks for certification (not sure though, and it may depend on which service pack you're on).

If you're using the driver via the Windows API, then there shouldn't be any problem; Windows will do the 3264-bit translations in the kernel. If you're trying to load the driver inside your own process, that probably won't be possible. As Dirk says you'll have to run it inside its own process and communicate through a COM server. I'm not sure what hoops you'll have to jump through if you have to run your driver in a higher-privilege execution level and want to make calls to it from user mode.

The only way to communicate between 32-bit and 64-bit dlls is to write a COM server that manages the communication (read: wrap EITHER the applications calls OR the 64-bit driver responses) in between.

One thing that came back to bite me: When I first wrote this COM server (yes, I too had to bear many sleepless nights before I came to know of this trick) I only built the 32-bit version of the (auto-generated) proxy/stub dll. Another bout of sleepless nights ensued before I came to know of the solution: Build the proxy/stub dll for both 32-bit and 64-bit. The 32-bit side deals with the 32-bit side (in your case the application) and the 64-bit with the 64-bit side (the driver). COM manages how the differnt versions of the proxy/stub talk to each other. And oh, do get the server registered on your system. Easy, right?

I think the whole point of a driver is to abstract away the actually workings of the hardware and present a common interface to the software. In this case, the PCIe driver needs to be 64-bit so that it can act as a go-between for Windows and the hardware, but I would think that a 32-bit application could then access the device without any troubles at all.

What's meant by that incompatibility you read about is that 32 and 64-bit assemblies can't be part of the same application - an application has to target either one or the other, though 32-bit application will generally run fine on Windows x64 using WoW64, which just acts as a translator.

You can use an ODBC connection to connect to your Amazon Redshift cluster from many third-party SQL client tools and applications. To do this, set up the connection on your client computer or Amazon EC2 instance. If your client tool supports JDBC, you might choose to use that type of connection rather than ODBC due to the ease of configuration that JDBC provides. However, if your client tool doesn't support JDBC, follow the steps in this section to configure an ODBC connection.

Amazon Redshift provides 64-bit ODBC drivers for Linux, Windows, and macOS X operating systems. The 32-bit ODBC drivers are discontinued. Further updates will not be released, except for urgent security patches.

You install the Amazon Redshift ODBC driver on client computers accessing an Amazon Redshift data warehouse. Each computer where you install the driver must meet a list of minimum system requirements. For information about minimum system requirements, see the Amazon Redshift ODBC connector installation and configuration guide.

Use the following procedure to download the Amazon Redshift ODBC drivers for Windows operating systems. Only use a driver other than these if you're running a third-party application that is certified for use with Amazon Redshift and that requires a specific driver.

After you download and install the ODBC driver, add a data source name (DSN) entry to the client computer or Amazon EC2 instance. SQL client tools use this data source to connect to the Amazon Redshift database.

We recommend that you create a system DSN instead of a user DSN. Some applications load the data using a different user account. These applications might not be able to detect user DSNs that are created under another user account.

For authentication using AWS Identity and Access Management (IAM) credentials or identity provider (IdP) credentials, additional steps are required. For more information, see Configure a JDBC or ODBC connection to use IAM credentials.

Enter a name for the data source. You can use any name that you want to identify the data source later when you create the connection to the cluster. For example, if you followed the Amazon Redshift Getting Started Guide, you might type exampleclusterdsn to make it easy to remember the cluster that you associate with this DSN.

Specify the endpoint for your Amazon Redshift cluster. You can find this information in the Amazon Redshift console on the cluster's details page. For more information, see Configuring connections in Amazon Redshift.

Enter the name of the Amazon Redshift database. If you launched your cluster without specifying a database name, enter dev. Otherwise, use the name that you chose during the launch process. If you followed the Amazon Redshift Getting Started Guide, enter dev.

Under Authentication, specify the configuration options to configure standard or IAM authentication. For information about authentication options, see "Configuring Authentication on Windows" in Amazon Redshift ODBC Connector Installation and Configuration Guide.

Choose a mode for handling Secure Sockets Layer (SSL). In a test environment, you might use prefer. However, for production environments and when secure data exchange is required, use verify-ca or verify-full. For more information about using SSL on Windows, see "Configuring SSL Verification on Windows" in Amazon Redshift ODBC Connector Installation and Configuration Guide.

Under Additional Options, specify options on how to return query results to your SQL client tool or application. For more information, see "Configuring Additional Options on Windows" in Amazon Redshift ODBC Connector Installation and Configuration Guide.

In Logging Options, specify values for the logging option. For more information, see "Configuring Logging Options on Windows" in Amazon Redshift ODBC Connector Installation and Configuration Guide.

Under Data Type Options, specify values for data types. For more information, see "Configuring Data Type Options on Windows" in Amazon Redshift ODBC Connector Installation and Configuration Guide.

Configure TCP keepalives on Windows to prevent connections from timing out. For information about how to configure TCP keepalives on Windows, see Amazon Redshift ODBC Connector Installation and Configuration Guide.

Use the steps in this section to download and install the Amazon Redshift ODBC drivers on a supported Linux distribution. The installation process installs the driver files in the following directories:

When you have finished installing the drivers, configure them for use on your system. For more information on driver configuration, see Use an ODBC driver manager to configure the driver on Linux and macOS X operating systems.

You install the driver on client computers accessing an Amazon Redshift data warehouse. Each computer where you install the driver must meet a list of minimum system requirements. For information about minimum system requirements, see the Amazon Redshift ODBC connector installation and configuration guide.

Use the steps in this section to download and install the Amazon Redshift ODBC driver on a supported version of macOS X. The installation process installs the driver files in the following directories:

If your macOS X system uses Intel architecture, download the macOS X Intel driver version 1.5.9. If your system uses ARM architecture, download the macOS X ARM driver version 1.5.9. In both cases, the name for this driver is Amazon Redshift ODBC driver.
