Running a 16-bit Application in Separate Memory Space from a File Manager or Explorer Association (156360)

MORE INFORMATION

1. Create a file named Write.cmd or Write.bat. Contents of the file should be:
   

      @echo off
      start /separate C:\Directory\Write.exe %1%
   						

   
   NOTE: You will have to specify the drive letter and directory where the executable file exists, or place the batch file in a directory and add that directory to your path in your environment variables in Windows NT.
2. 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.
   
   Start Registry Editor (Regedt32.exe) and Edit the registry entry for the file association. Look for the file extension under the following registry key:
   HKEY_LOCAL_MACHINE\SOFTWARE\Class
   
   Using Write.exe as an example, you would look for ".wri" under this registry key.
3. Select this entry, and in the right-hand window of Registry Editor, you will see the folder or file type this extension is associated with. For example:
   HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.w
   
   The right-hand window will display:
   

   <No Name> :REG_SZ : wrifile

4. You will find this folder further down in the Classes subkey. For example:
   HKEY_LOCAL_MACHINE\SOFTWARE\Classes\wrifi
   
   To change the association in the registry, you must change the string located under the following key: (again using Write.exe associations for example)
   HKEY_LOCAL_MACHINE\SOFTWARE\Classes\wrifile\shell\open\comma
   
   The value that will appear in the right hand window should be similar to below:
   

        <No Name> : REG_SZ : Write.exe %1
   						

   
   In Windows NT 4.0 it will look similar to the following:
   

        <No Name> : REG_SZ : C:\Program Files\Windows NT\ 
                             Accessories\Wordpad.exe "%1"
   						

5. Double-click on the value that appears in the right-hand window and edit the string to reflect the new batch file or CMD file association. This will be the batch file you created in step 1.
   
   After you edit the string, it should appear similar to the entry below:
   

        <No Name> : REG_SZ : C:\<YourDirectory>\Write.cmd %1
   						

   
   In Windows NT 4.0 it should look like the following:
   

        <No Name> : REG_SZ : C:\<YourDirectory>\WRITE.CMD "%1"
   						

   
   NOTE: The quotation marks in the Windows NT 4.0 registry setting C:\<YourDirectory>\ reflect the drive and directory structure to where your batch or CMD file exists.
