HLVDD Hardlock virtual driver
Several people have apparently had the same problem I had with failing
setup.exe (or other) programs which used the 16 bit susbsystem in Windows
XP. An NTVDM error is generated indicating a problem initializing the
HARDLOCK virtual driver.
The solution to this problem for me was to download the latest Hardlock
driver from www.ealadin.com. I do not fully understand why Windows needs
this, as I have never used a hardware dongle or other lock on this system.
However, it resolved the issue and may be helpful for others.
