Civil 3D 2009 w/ LDC

[Anonymous]

One of my users running Civil 3D 2009 w/ LDC and Civil 3D 2012 is getting this trying to load LDC, it was working fine until yesterday afternoon.  This came up before and to fix it the entire computer was reimaged but now it's happening again.  Is there an issue running the two versions simultaniously?

Regenerating model.

I have both applications installed and they both work fine together.

Hvae you tied to repair the install of LDC from the control panel?

The repair is running right now on the computer.  We did run the repair the last time this happened as well as a complete uninstall and reinstall without success before reimaging the computer completely.

These may help you avoid completely reformatting the HD in the future.

Did you apply all of the updates to LDC and C3D?

Do you have custom programs running in C3D or LDC? Does the issue go away if you uninstall them?

Can you reproduce the error with a new user on the same PC?

Yes, it is all up to date, we don't have custom programs that i know of ( I am the IT tech, not an autocad user), and no, this is the only person having this issue, it hasn't been seen on any other users we have running 2009 and 2012.

Which OS? Are all users on the same OS? Do they all have the same user rights? If your on Vista or Win 7 can you get the app to run if you right click on the icon and choose Run as Administrator?

These are things I would look to rule out before reinstalling. If it came to that and if I really wanted to start clean, I would do a clean unistall as per the docs above for both apps. If these were the only Autodesk programs installed I would consider a registry cleaner to verify the Autodesk entries were all removed. Reboot and make sure all systems are go. Install LDC and update. Verify install. Install C3C. Verify both installs.

...but make sure you remove that registry cleaner after removing adsk entries.  These cleaners DO NOT get along well with Autodesk products.

Good point Matt and thanks. I was careful with the recommendation as well. Running a reg clean with other products/versions installed could mess things up pretty bad. As always with these apps, use at your own risk 🙂
