I just tried to load DataCAD 11 onto Windows 8 and it is saying the HLVDD.DLL file is missing. Is this DataCAD version just too dated, or is this a Windows 8 compatibility issue, or other?

Ron,

You probably need to download the latest hardlock driver from the DataCAD website:

Also, maybe you should consider upgrading to v15 - v11 came out before WinXP was out, I think?

Thanks to Ron asking this question and Neil answering it, I have resolved the same problem that I was having.
I had a computer crash and replaced it. When I loaded my legacy versions of DataCAD, I got the missing DDL message. I used Neil's suggestion and now I have the legacy versions when needed and my Version 15 for all of the important stuff.

I am having a similar problem. Where is the answer that Neil gave?

Thanks for the help.

Yes, I believe XP came out very shortly after V11 and made all the original CDs out of date. Trouble is, we all forget about it. I just set up V11 under windows 7 last week. It runs fine with the new driver.

I recently loaded my old datacad 11 on a new laptop with windows 8 and it loaded fine from the disc but when I try to load the last update (11.08.01) it won't load. I will see the installation window briefly but then it is gone and nothing happens. When I open task manager it shows the application as running but nothing happens. Is it possibly a 64bit v. 32bit issue?
Thanks.

Download the upgrade file from Datacad to your hard drive and run it manually. For some reason Windows 8 has a problem with Datacad's automatic update.

Thanks Paul. I did download and run the upgrade outside of datacad and had the same issue. The installer shows up for about a tenth of a second and then disappears.

Where is DataCAD 11 installed? If it is in one of the Program Files folders, then you need to uninstall it, and do a Custom installation to C:\DataCAD 11 instead.

It was installed in the Programs(86x) folder. Unfortunately I uninstalled it and now the install will not run from the disc as before. It gives me the administrator warning and when I clock ok it does nothing.
I think it may be a windows 8.1 issue. I originally installed it before i updated to 8.1. Unfortunately there is apparently no way back from the upgrade. any thoughts on getting it to load? the downloaded update won't load either.
thanks for your help.

Try turning off User Account Control. The easiest way to do this in win8.1 is to use the Windows key + S to bring up the search dialogue box, type in UAC, select Change User Account Control settings. I have mine set to never notify. You can always change it back later.
Next I create a folder called apps on whatever dive the mood took. Under apps I create a folder for datacad. On my machine I have
d:\apps\Datacad14
d:\apps\Datacad15
d:\apps\Datacad16

Now I haven't installed 11 on this machine but if I did I would then right click on the install file and select run as administrator - do a custom install - and just install the parts I require.

If the install program doesn't run try turning off the windows firewall. If that doesn't work I would normally use System Restore to restore the system back to just before you installed Datacad 11 the first time BUT since then you have installed Windows 8.1 so that won't be an option.

I just did a test install of x3 on my win8.1 virtual machine and it installed without any problems. Couldn't lay my hands on ver 11. Used system restore to remove it.

Hope you succeed but if you don't maybe an upgrade is in order.

Still no luck. I don't know if I should try to get back to Windows 8 or just upgrade to dadacad16 though 11 still works just fine for me.
Thanks.

Upgrade to V16 - DC LLC's added a TON of new functionality since V11 and it's well worth the upgrade price!
