First back up the registry first as the article suggests. I am running win 2000pro also but my symantec is antivirus and systemworks. I suspect my dll relates to the systemwork. As there is nothing to click on in the right panel I am not sure you will be able to edit it. I also did the steps in the other 2 articles that I posted just so I could follow along. They are not dangerous steps if you have not done them. On the second article I stopped after verifying that my ntvdm subsystem was running. Note the following: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ VirtualDeviceDrivers This key stores the device drivers to be used in a NTVDM session. These entries are created by Windows Setup when a device driver is installed.

Martin, Please post the names of those 2 programs you are trying to install. Perhaps we can find something out about them on the internet that will assist you.

Posting info on virtual device drivers for win 2000. searchwin2000.techtarget.com In Windows, a virtual device driver is a program for each of the computer's main hardware devices, including the hard disk drive controller, keyboard, and serial and parallel ports. They're used to maintain the status of a hardware device that has changeable settings. Virtual device drivers handle software interrupts from the operating system rather than hardware interrupts. interrupt An interrupt is a signal from a device attached to a computer or from a program within the computer that causes the main program that operates the computer (the operating system) to stop and figure out what to do next. Almost all personal (or larger) computers today are interrupt-driven - that is, they start down the list of computer instructions in one program (perhaps an application such as a word processor) and keep running the instructions until either (A) they can't go any further or (B) an interrupt signal is sensed. After the interrupt signal is sensed, the computer either resumes running the program it was running or begins running another program. Basically, a single computer can perform only one computer instruction at a time. But, because it can be interrupted, it can take turns in which programs or sets of instructions that it performs. This is known as multitasking. It allows the user to do a number of different things at the same time. The computer simply takes turns managing the programs that the user effectively starts. Of course, the computer operates at speeds that make it seem as though all of the user's tasks are being performed at the same time. (The computer's operating system is good at using little pauses in operations and user think time to work on other programs.) An operating system usually has some code that is called an interrupt handler. The interrupt handler prioritizes the interrupts and saves them in a queue if more than one is waiting to be handled. The operating system has another little program, sometimes called a scheduler, that figures out which program to give control to next. In general, there are hardware interrupts and software interrupts. A hardware interrupt occurs, for example, when an I/O operation is completed such as reading some data into the computer from a tape drive. A software interrupt occurs when an application program terminates or requests certain services from the operating system. In a personal computer, a hardware interrupt request (IRQ) has a value associated with it that associates it with a particular device. A list of sites for downloadable device drivers: microsoft.com In Windows operating systems, a device driver file usually has a file name suffix of DLL or EXE. A virtual device driver usually has the suffix of VXD. zdnetindia.com

since you do not have vdd, skip the delete step and just add it. This group of posts mentions having adjusting a 16 bit subsystem in windows that eliminated the error message. pub3.ezboard.com This tells it like it is(just substitute the name of your program)<g> "16-bit subsystem... Virtual device drivers format in registry is invalid" The Quicken installer contains 16-bit code and requires a functional 16-bit subsystem for a successful installation. If you are running Windows XP, NT 4.0, or 2000, and critical files that are needed to enable the operation of the Windows Virtual DOS Machine (NTVDM) 16-bit subsystem are missing or corrupt, your system will not be able to run 16-bit utilities, such as the Quicken installer, that require Windows NTVDM. When installing Quicken, the message "16-bit windows subsystem system\ CurrentcontrolSet\ Control\ Virtualdevicedrivers\. vdd Virtual device drivers format in registry is invalid" will occur. To resolve this issue, contact your computer manufacturer or Mircosoft. For more information, see knowledge base articles Q222975 and Q165214 on Microsoft's Web site. intuit.com
