AutoCAD LT 2005 will not start...

I am having a very strange problem, and I am hoping that someone will have some insight for me:

After not using the program for a few months I went to start it up to make a drawing...And nothing happened. When I double-clicked on the icon, the HD light went on for a fraction of a second and then nothing. I tried clicking on a drawing file to start it up, but I got the error message, "Window cannot find '(null)', and the program never starts.

After looking around the knowledge base and not finding anything like this, all I could think of trying was uninstalling and reinstalling. I did the uninstall and followed the knowledge base instructions to remove all remaining files and registry entries. I reinstalled the program and downloaded the service pack. But it still does the exact same thing...NOTHING!

The program used to work fine, now nothing.

Does anyone have any insight into this problem?

I am running an AMD Athlon64 3500+ on an A8V motherboard. 1Gb dual channel RAM, WinXP Home Edition.

Thanks for any help,
Mark Abbott

Did you manually delete the Autodesk key from your registry?

As I stated above, I followed the instructions found in Knowledge Base to remove all the remaining AutoCAD entries from the registry.

The only way I was able to resolve this problem was to wipe my hard drive and reinstall Windows and reinstall AutoCAD. Gee fun...

I am presently having fun with this ‘exact’ problem.

I am running on an AMD Atholon64 3500+ on an A8N-E motherboard. 1.5Gb RAM, WinXP Pro with SP2.

This issue began after uninstalling the AutoDesk Land Desktop and Civil Design software and rebooting the machine. I have wiped the registry, uninstalled, reinstalled, and rebooted in every possible combination trying to get AutoCad LT 2004 to start again to no avail.

Looks like a full reinstall of windows for me as well… what a waist of time!

The problem described in this thread (see jebebara's 5/12/05 message)
started affecting my Autocad LT 2005. I spent much time searching the
newsgroup for a solution, but there was nothing useable in any of the
postings.

Here, now, is the solution that Autodesk Safety Net Support gave me. It was
easy to make these changes and Autocad LT started working again.

Background: My computer is an Asus Z80K with Windows XP SP2. I had been
using Autocad LT successfully for about 9 months. There was a lapse of
time, perhaps 1 month that I did not do any drafting. Then when I next
tried to start Autocad LT by double clicking on the icon, the hourglass
symbol showed momentarily and nothing happened, no error message, and no
Autocad LT opening screen. If I tried to open a drawing by double clicking
on the drawing name, I received an error message stating that Windows could
not find the file. I downloaded Autocad LT SP1 and installed it. Still,
got same results.

Analysis: The problem occurs due to Windows XP SP2.

Solution:
1. Go to Control Panel / System / Advanced / Performance / Settings / Data
Execution Prevention. Click to activate the bullet which says "Turn on DEP
for all programs... except ...". Click on Add, then browse to folder
Autocad LT 2005 and find the file aclt.exe. Select that file and click
Open. This should add the aclt.exe program to the list in the DEP window.
(Note: on my system the program name is "not applicable".) Click OK twice.
You should now be back in Control Panel.
2. Click to open Internet Options / Advanced. Scroll down to the Security
section and uncheck the box which says "Check for publisher's certificate
revocation." Click OK. You should now be back in Control Panel.
3. In the menu bar (of Control Panel), choose Tools / Folder Options / File
Types. Scroll down and verifiy that DWG is associated with File Type of
Autocad LT Drawing. If you select DWG, it will show in the details box (at
bottom) the Autocad LT icon and (at least on my system) the words "not
applicable". Click OK. You will now be back in Control Panel. Just close
it at this point.
4. Autocad LT should now work.

I have noticed that most of us who are having this problem are running AMD Athlon64 processors. Hmmm...

My problem is that after some pretty hard usage, especially if I am working on several drawings (opening and closing a lot), at some point ACLT2005 just fails to open, either from the icon or from clicking a drawing. Reboot and all is well. Really aggravating.

I will try the fix offered in this thread and see what happens.

AMD Athlon64 3400+ 1.5G ram Gigabyte MB & Parhelia256 w/ 3 flatscreens - It's a love / hate relationship.

Thanks,

Also somewhat late!

I am using an Intel Core 2 quad with 4GB ram Windows XP pro sp2 and had the same problem. No start with ACLT 2005.

Thanks Rusty, it now works.
Goodness knows how it decided to stop working. Now I have to restore the pgp file and all my aliases...
