If You Have Trouble Installing X(PLORE)

Some users have reported getting the message "Configuring Windows(R) installer" while installing, followed by nothing. The installation fails. If you get this or any other error, you can manually install X(PLORE). 

  1. Create a folder for X(PLORE). Using Windows Explorer, open the folder C:\Program Files and create a new folder XPLORE within this folder.
  2. Download the file X(PLORE)_Files.zip, a compressed file that contains all the files you need to run X(PLORE). To download the file, click here (2.4MB, 3/27/02), and save the file in the folder you just created.
  3. Use Windows Explorer to find the file X(PLORE)_Files.zip and unzip it. This will cause all the files compressed in X(PLORE)_Files.zip to be expanded and stored in the same directory. Windows Explorer will show all these files in the directory C:\Program Files\XPLORE\. You can delete the file X(PLORE)_Files.zip if you wish.
  4. X(PLORE) uses an ActiveX component that you must register with the operating system. The component is tbc.ocx, and the program that registers it is regsvr.exe or regsvr32.exe.  To registers your component, click on Start, then Run... , then enter the following string into the box labeled with "open:"

            c:\winnt\system32\regsvr32.exe "c:\program files\xplore\tbc.ocx"

  1. then click on "OK".  You will have to adjust this entry to fit your computer.  The quotation marks around the path to tbc.ocx are necessary. Any path name that includes a space must be placed in quotes.

With this manual installation, you won't get an icon on your desktop or Start Menu, but you can click on xplore.exe in the folder C:\Program Files\XPLORE\ to run X(PLORE), and by right clicking and dragging the program to the desktop, you can create an icon there. 


To download a copy of X(PLORE) for DOS (with help file but without manual--286KB) click here. (If your browser has difficulties downloading an executable file, try shift-click, then select "save this program to disk" or a similar option.

To install X(PLORE), place the downloaded file XPLDOS.EXE in a directory created for X(PLORE) and run it. All the files you need will appear in your directory. To run X(PLORE) for DOS, execute XPL.EXE .

X(PLORE) for DOS is a small, fast program that will run effectively on any 486 or greater CPU. I have run this program successfully on all versions of Windows through NT4.0 and 98. This is the original 1993 Prentice Hall X(PLORE) that is limited to 640K of memory. Later DOS versions that use extended memory unfortunately do not run under the most recent incarnations of Windows 98 or Windows NT.
