So I was able to load the software to my new Windows Surface Pro. But when I try to open the program I get a message saying "This program cannot start because HLVDD.DLL is missing from your computer. Try re-installing the program to fix the problem." So I've tried to reinstall to no avail. Any suggestion? Thankxx

Well, THERE'S the premier reason to upgrade to V16 if you want/have to move to Windoze 8!

I just got v11 running in Windows 8 on a new laptop.

I set the program "Compatibility" to Windows 7 and followed the "X3 Hlvdd.dll Windows 7 x64 Hardlock failiure" instructions for the hardlock workaround. Only difference was copying the new hlvdd.dll to "C:\Windows\SysWOW64" then making sure the hardlock was in a USB 2.0 port. Seems to be running fine so far.

Now to install v15 and see what happens....

Still a good reason to upgrade to v16, I'm only running v11 because a Client wanted me to. :shock:

Time to get a new client?

:twisted:

Thanks for adding to the knowledge base Stuart! Just another reason this forum (and program) are so great!

I agree with Stuart Jackson. Install the updated driver. Then find the Hlvdd.dll file in the "c:\windows\system32" folder and copy it into the "c:\windows\SysWOW64" folder. I also copied Aladdin Hardlock Key files in the SysWow64 folder too. Then I installed DataCAD 11.

Everything worked like a charm.

You guys keep finding ways to run ancient versions of DataCAD on your new hardware with its new OS and I'll be making my retirement plans sooner than I had hoped. :?
