Create a zero-byte file

During the installation of Visual Studio 6 on Windows 7, it is necessary to create a zero-byte file called MSJAVA.DLL in the Windows directory. The mere presence of a file with this name will allow installation to proceed. Without it, installation dies.

I've been getting quite a few questions from folks lately, asking "Just exactly how do I create a zero-byte file?" There are several ways to do it. Read on to find out how to do it at the command prompt.

But first, why do we need to create this file?

One of the requirements of Visual Studio 6 is the installation of a "recent" version of Java, particularly of the Microsoft variety. The installation program for Visual Studio is kludged, so it simply checks for the existence of a file with the name MSJava.DLL in the C:\Windows directory.

If this file does not exist, the setup program will force you to install it. Further, it forces a reboot of the operating system in order for the changes to take effect.

Now, we don't want some moldy old Java from over a decade ago cluttering up our shiny Windows 7 machine, so to bypass this funky requirement, we will create a zero-byte file with the proper name and in the proper location by following these steps:

  1. Open an elevated command prompt (run as administrator).
  2. Type the following lines in the command prompt:
  3. After hitting enter, you'll just a blinking cursor. Just press F6 and enter, and your zero-byte file will be created.
There, mission accomplished. You can now run setup for Visual Studio 6, and you won't be forced to install stale Java.

Or open a .txt file using wordpad and save it without typing anything into it.

I'm sure there are about 400,000 methods for creating a zero byte file.... Thanks for the contribution.

I'm not very tech savvy. I've created a 0 byte file in C:Windows. So is that all I have to do to run setup successfully? Are there any other steps? I really want to learn programming. I've taken a VB6 book from the library and am also going to purchase a VB6 book from Amazon. Any pointers would be greatly appreciated.
Thank you!
