This application note will describe the process for removing MDAC, when the ODBC connection works, but when Spectrum or Satellite won’t connect to a database.
For information about what MDAC is and why you need to have it, see the application note describingMDAC.
ComCheck
ComCheck or component checker analyzes your system components and diagnoses possible problems. It checks for errors in two places. First, it scans the header information of all the .dll files in the Windows® registry and WindowsSystem file folder to determine if the .dll is the most up to date version. Current versions of many .dll files can be downloaded from the Microsoft® website. Second, it determines the version of MDAC installed. Often, there are program conflicts between different versions of MDAC. To download the version of ComCheck related to this application note, you can go tohttp://www.spcsoftware.com/download/msutils/cc.exe. If you want the newer version of ComCheck, you can get it from Microsoft athttp://support.microsoft.com/default.aspx?scid=kb;EN-US;q307255.
First, you need to have the MDAC component checker previous to version 2. To check this, open the component checker and the title bar should not say 2.0.
To remove MDAC, follow the instructions given below. This process will only remove MDAC versions up to 2.6. If MDAC 2.7 is already installed on the system, there is no need to install the redistributable.
The following is from the comcheck readme file:
This section describes how to determine which version of MDAC you are currently running on your computer.
To determine the MDAC version on your computer/how-to-extract-wad-files.html.
1.Run MDAC ComponentChecker.
2.In the ComponentChecker—Choose Analysis Type window, select Perform Analysis of your machine and automatically determine the release version, and clickOK.
The program attempts to identify the MDAC version on your computer, based on versions of the core MDAC files. If a given snapshot of the MDAC files has more matches for one version than for other versions, you receive the following message:
Mdac 2.7 Sp1 Windows 10
The version which closely matches your machine is XXXX.
The program then uses the identified version to complete the analysis. If the snapshot identifies more than one version of MDAC on your computer, the program notifies you and asks you to select a version from a drop-down list.
This section describes how to remove MDAC components from your computer.
To remove MDAC components
1.Run MDAC ComponentChecker using the /D command-line option.
2.In the ComponentChecker window, select the build that best matches the one on your computer, and clickOK.
3.When the analysis completes, click Delete or, on the File menu, click Remove MDAC Components.
This produces a warning message asking you to confirm your action.
4.Click Yes to proceed.
If there are components in use that would prevent the successful removal of all MDAC components, you receive an error message telling you so. When you dismiss the message, the in-use components are displayed in the Summary Report view. (See the 'Show Components in Use' section of this document for information about showing in-use components without performing a removal.)
When the program has verified that it can successfully remove the MDAC components, it prompts you for a redistributable .exe file, to be run immediately after the removal has completed. (See the description of the /NR option in the 'Command-Line Options' section of this document for information on how to skip this step.)
5.Specify an .exe file for the Install program for the version of MDAC that you want to use.
The program then removes your MDAC components and runs the redistribution program. When the redistribution program finishes, the ComponentChecker shuts down.
Note The files that the program doesn't remove are listed in the DeleteExceptionList.csv file in the Streams subdirectory in which you installed the program. This is simply a text file that you can edit to customize files that are not removed.
Once MDAC is removed, restart the computer.

-->The following are some frequently asked questions about the data access technologies included in Windows Data Access Components (Windows DAC) and Microsoft Data Access Components (MDAC).
What Is the Difference Between Windows DAC and MDAC?
Windows Data Access Components (Windows DAC) 6.0 is the version of the data access technologies—ADO, OLE DB, and ODBC—included in the Windows Vista operating system. Microsoft Data Access Components (MDAC) includes earlier versions of the same technologies, and version 2.8 was included in Windows XP and Windows Server 2003. There is also a redistributable version, MDAC 2.8 SP1, which should only be used with Windows 2000. Windows DAC includes some changes to work with Windows Vista, but is almost entirely functionally equivalent to MDAC 2.8.
What version of Windows DAC or MDAC is current for my operating system?
The followin Knowledge base article contains information about WDAC and MDAC versions for supported Microsoft operating systems: Microsoft Data Access Components (MDAC) release history.
Can MDAC be removed? It is causing problems with one of my applications.
MDAC can be removed in some instances where it is not installed as part of the Windows operating system. For example, MDAC 2.7 cannot be removed from systems that are running Windows XP, because it is a Windows component and therefore all its assemblies are system-protected files. The same is true for MDAC 2.8 when it runs under Windows Server 2003.
In most cases, you should use the Microsoft Component Checker (ComCheck) utility, which is available at no charge and can be downloaded from the Microsoft Web site.
For more information about how to use ComCheck to remove or repair MDAC installations, refer to the following Microsoft Knowledge Base article:

Why am I having intermittent problems with my C++ application that uses ADO components when it runs under 64-bit Windows?
When you compile C++ applications that import msado15.dll, make sure that the 64-bit version of msado15.dll is referenced and not the 32-bit version. This detail might not be immediately obvious for the following reasons:
Many developers must build their 64-bit applications on computers that run under 32-bit Windows operating systems. These computers typically do not have the 64-bit version of msado15.dll installed.
When you build a 64-bit application that is referencing the 32-bit version of msado15.dll, the Visual C++ compiler does not return any compile or linking errors. In fact, frequently, your application might appear to work. Occasionally, your 64-bit application might encounter misaligned data. This causes memory access violations when certain ADO properties are accessed.
Mdac 2.7 Windows 10
To avoid this issue, you can copy the 64-bit version of msado15.dll from the Windows installation media to any 32-bit computers that you use to develop, build, or test your application and make sure that you use that version when you compile your 64-bit application.
I get RDS errors after upgrading from Windows 2000 to Windows XP or Windows Server 2003 and it appears MSADC is no longer available on my IIS server. Why is that?
When Internet Information Services (IIS) is installed under Windows 2000, the default is to install data access components and create the MSADC virtual directory needed to support their use at the Web server after setup. Together, this configuration provides the support your Active Server Pages (ASP) applications might need to use Remote Data Services (RDS) and work as intended. After upgrading to either Windows XP or Windows Server 2003, however, the MSADC virtual directory is removed from IIS. This behavior is by design and is intended to provide added security where data access components are not available for use unless you intend to use them on your server running IIS.
After upgrade, if you try to access RDS, you might receive the following error message:
To resolve this problem, create a new MSADC virtual directory on the server running IIS. To do this, follow these steps:
Click Start, click Programs, click Administrative Tools, and then click Internet Information Services.
Expand the (local computer) and Web Sites nodes.
Right-click the Default Web Site node, point to New, and then click Virtual Directory. When the Virtual Directory Creation Wizard appears, click Next.
In the Virtual Directory Alias dialog box, type MSADC, and then click Next.
On the Web Site Content Directory page, click Browse to locate the following path, and then click Next:
On the Access Permissions page, click to select the Execute (for example, as ISAPI applications or CGI) check box.
Note
By default, the Read and Run scripts such as ASP check boxes are selected.
Click Next, and then click Finish to complete the wizard.

After you follow these steps, you might not receive the RDS error previously described.
