Hi Pete,
There may be several issues - you may need to do a custom installation,
and change the default location to C:\DataCAD 11. (Some older versions
of DataCAD installed to C:\Program Files by default.)
You probably need to get the latest hardlock driver installer:

It is also possible that DataCAD 11 won't work in Windows 10? DataCAD 11
is at least 15 years old, and Windows XP was the newest version, at the
time. I was still using Windows 2000, and only switched to WinXP after
SP2 came out.
