AutoCAD 2011 LT crash at startup

[crioced]

Hi,

i was installling Autocad 2011 LT on a machine where i was using previously Autocad 2012 LT.

I did the uninstallation of acad12lt and after a reboot i disabled the AV software.

Then I started the installation of the 2011 release and all was working well.

After all when i try to start Acad11lt it crashes on startup without any popup...

I tried several things checking the forum with no result:

1° flexnetlicensingservice put in "automatic"

2° I put at the end of the short cut link quota “/nohardware”

3° Updated Nvidia Quadro 600 drivers

Still doens't work. Any more suggestions?

Thank you for your help

I FOUND THE SOLUTION!!!

First of all you need to uninstall every version of AutoCad you installed before, and delete every file that is associated with AutoCad, that means and those files that are located in Regedit, here is  a link how to do uninstall all that and delete all these files:

And then after you uninstalled everything and deleted all files, you install your latest version and everything works.
