Run 3. 2- bit applications on x. Windows servers. The x. Windows is not capable of natively running 3. Because most applications are 3. By submitting your personal information, you agree that Tech. Target and its partners may contact you regarding relevant content, products and special offers. Microsoft has created a new folder named \Windows\Sys. WOW6. 4 that is used to store the 3. DLLs. In the 3. 2- bit version of Windows, DLL files are normally stored in the \windows\system. However, the x. 64 version of Windows uses the \windows\system. DLLs. As you can see, the WOW6. But keeping DLL files separated is only the beginning. The WOW6. 4 emulator performs file system redirection for several key components of the Windows operating system. Another location in Windows where file system redirection is used is the Program Files folder. Almost every application you install it gets installed to the C: \Program Files folder. Because each application is installed in a separate subfolder, the Program Files folder seems like an unlikely target for file system redirection. However, in the x. Windows, only 6. 4- bit applications are usually installed in the Program Files folder - - 3. Program Files (x. However, the Program Files folder may not always be in the same place on every computer. I have seen deployments (admittedly few and far between) in which Windows was installed on a secondary hard drive. As such, most application developers do not hard- code the c: \Program Files path into applications. Instead, Setup programs usually make a call to an OS function known as SHGet. Special. Folder() in order to determine the exact name and location of the Program Files folder. Because most applications are 32-bit, the x64 version of Windows makes use of an emulator known as WOW64 to allow 32-bit applications to run. Use the Office offline installer to install Office 2016 or Office 2013 if you don't have an active Internet connection or you're having problems with slow speed or. The Microsoft SQL Server 2014 Feature Pack is a collection of stand-alone packages which provide additional value for Microsoft SQL Server. Great article. A few notes on my experience in getting Excel 2013 to use ODBC to DB2 via MS Query on Win7 64bit First, had to use the 32 bit driver (think MS Query. Although this bit of information may seem trivial, it is useful in making sure that applications are installed to the correct folder. In the 3. 2- bit version of Windows, the SHGet. Special. Folder() function is used to determine the name and location of the Program Files folder. But in the x. 64 version, the function looks at whether the Setup application was running 3. Application installation is not the only time when the Program Files folder is referenced; it may also be referenced during application run time. Although there are several ways that an application can determine the name and location of the Program Files folder, environment variables are often used. In a 3. 2- bit version of Windows, the %Program. Files% environment variable contains the path to the Program Files folder. In an x. 64 version of Windows, this environment variable is still used, but it works differently. Tutorial: Accessing detailed file information provided by the Operating System. ![]() The most important rule of the x. Environment variables are often called from within scripts. That being the case, running scripts can get a bit tricky in a 6. Should Windows treat the script as 3. The answer affects not only the contents of the environment variables, but also which external programs the script can call. For example, a 6. Windows gets around these issues by offering two command prompts: one 6. Environment variables are set according to which command environment is being used. For example, if you open a command prompt by entering the CMD. EXE command at the Run prompt, Windows will open a 6. In most cases, the %Program. Files% environment variable for the command environment will be set to C: \Program Files. If you run a script, the script can interact with 6. On the flip side, if you enter the C: \Windows\Sys. WOW6. 4\cmd. exe command at the run prompt, you'll be running a 3. In that case, the %Program. Files% environment variable will be set to C: \Program Files (x. As you can see, the location of the Program Files folder is redirected depending on whether you're running 3. But there's one exception to this rule. If an application has the C: \Program Files path hard- coded, then C: \Program Files will be used, even if the application is made up of 3. Folder redirection does not occur for hard- coded paths. Fortunately, hard- coding paths is not a common programming practice. About the author: Brien M. Posey, MCSE, is a Microsoft Most Valuable Professional for his work with Windows 2.
