LLD 4.0 won't start

[skymapper]

Hi,

I have downloaded and installed the LDD 4.0 program. When i click on the desktop shortcut or go via the start menu, nothing happens. I can see LDD.exe appear in task manager, gradually eating up more and more RAM, until it gets to about 500Mb, then disappears.

When I click on the icon, i get nothing, nada. not a sausage.

My PC specs are:

OS: Windows XP Pro

Processor: AMD dual core processor 64bit @2Ghz

Memory: 2Gb RAM

Graphics Card: nVidia Geforce 6200 Zotac 256Mb (And yes, the latest drivers are installed)

Any ideas please? I've tried uninstalling and reinstalling, I've deleted the files in c:\documents and settings\ etc. but nothing. The official lego website for this is worse than hopeless.

Have you tried the suggestions here, here, and here?

Hi,

Yes, yes and yes.

The LDD program still does not work. It's not like it's an underpowered PC I have...I'm using it for Remote Sensing and GIS work...4 disk RAID 0+1 setup too!

I've installed MLCAD and that's working great...My mate said LDD was <censored> and not to bother using it. Seems he's right.

I've been looking on the interweb and it seems a great many people are experiencing this non starting issue. This is a fresh install for me, btw, I've not had any other version of LDD.

Think Lego need to pull their fingers out and get it sorted.

Can't help you there, then. Sorry.

I'm not sure what the real problem is, because a lot of people can get it to work. (myself included) EDIT: Well, to be fair, I run the Mac version, and I have yet to encounter a single person who couldn't run that. But I do know there are members of this forum who run LDD 4 on a Windows machine. Edited March 15, 2011 by Brickdoctor

Hi,

you can alway try SR3DBuilder. You won't be afraid!

Thanks for the help.

I'm not sure even Lego know what the problem is either! Their 'help' pages are worse than useless. Their only advice for the non starting issue is 'Install the latest graphics gard drivers' (!?) I already have the latest drivers from nvidia (which have openGL in them).

Eh, LEGO's help for LDD usually isn't the greatest. One of our members in the topics I linked to had to downgrade drivers to get it to work.

Thanks for that...I'll look into that as well. All I want is to be able to build something in CAD, then get a parts list and build it for real. :)

Holy Cow....now that is sad.... LMAO!

Yep, Lego really need to pull finger on this one!!

I have tried all sorts to get it to run on my laptop but it wont, fortunately works on my desktop so do all my work on there, though that doesnt have a net connection so I am a bit limited to what I can do.

I've given up on LDD. I'm using MLCAD now :)

I would encourage you to follow up on Sergio's suggestion and try SR 3D. It allows you to bend flexible pieces, rotate gears in-program, and align hinged pieces much more accurately than LDD, among other things. One of the demo videos shows the front axle for a car with independent suspension functioning in-program.

Hmm....today I installed LDD 4.0 on my Compaq Presario 2100 laptop with winders XP pro and it works...This laptop is several years old, and it generally struggles with 3D stuff, but it ran LDD 4.0 just fine...

I've tried again on my dual core super computer and it still won't run. I uninstalled flash player and let LDD 4.0 install it, still nothing. It starts and appears in task manager but nothing else.

Do any of the Lego techies read these forums? If so, can we have some sort of response please?

I had the same problem as you. All of a sudden, i couldn't start LDD 4.0 anymore (it "kinda" worked before... kinda as in ran with the problem of vanishing on very specific functions). When i ran it, nothing happened... LDD.exe was starting to fill up the memory (as you described) up to about 500 mb (same as yours) then dissapeared from process list.

I did manage to repair it by simply deleting everything connected to LDD (\Program Files\LEGO Company\LEGO Digital Designer, \Documents and Settings\<username>\Application Data\LEGO Company). After a "fresh" install of LDD 4.0, it started to work again.

The wierd thing is that after reinstall, when i work with LDD 4.0, i get the FFDShow icon in tray (might be connected with the default settings - LDD has by default enabled sound). When i disabled the sound, the icon disappears.

OH!!! I've got it working!!! :) Thanks!! Like you said, I deleted the folder in c:\..\<username>\Application Data\Lego Company and it's working fine!!! It seems this program drops folders in 3 different places...I only deleted them in two other places mentioned earlier.

I have no idea what's going on. I can only assume the first time I ever installed it and tried to run it, something went pear shaped which prevented it from running, because I saw the initial screen appear, albeit completely white, then it disappeared after a few seconds, since then nothing.

And it's nice to have this spread across two 19" widescreen monitors :)
