IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS
You may not be able to install Windows 95 DDK after you install the Microsoft Windows Platform Software Development Kit (SDK).

Windows 95 DDK requires that Win32 SDK be installed before you install the DDK. The DDK Setup program looks for specific keys in the registry to confirm that Win32 SDK is installed.

CAUSE
Microsoft Windows Platform SDK doesn't create the registry keys that are required by the Windows 95 DDK Setup program. Earlier versions of the SDK (called Win32 SDK) create a key called "Win32SDK" in the system registry. The DDK Setup program searches for this key; the newer versions of the SDK (called Platform SDK) create "Platform SDK" instead.

RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).

You can correct this problem by installing the latest the Platform SDK. To correct this problem without reinstalling the Platform SDK, create the required registry keys manually. Please note that different registry keys are required depending on the target operation system (Microsoft Windows 95, Microsoft Windows 98, or Microsoft Windows NT).

To install Windows 95 DDK on a computer that is running Windows 95 or Windows 98:

  Create the following registry entry: "HKEY_USERS\.DEFAULT\Software\Microsoft\Win23SDK" Note the period (.) that precedes DEFAULT.  Create the following registry entry: Add a string value named Install Dir. Note the space between Install and Dir. Type the folder where you installed the Platform SDK (for example, C:\Platform SDK) as the value data for Install Dir. Run the Windows 95 DDK setup program.

To install Windows 95 DDK on a computer that is running Windows NT:


 * 1) Create the following registry entry:
 * 2) Create the following registry entry:
 * 3) Add a string value named Install Dir (note the space between Install and Dir).
 * 4) Enter the directory where you installed the Platform SDK (for example, C:\Platform SDK) as value data for Install Dir.
 * 5) Run the Windows 95 DDK Setup program.
