I found a solution for the people that reinstalling and renaming the files did not work.
1: Pull up run and type in services.msc
2: Ckick on the standard tab at the bottom.
3: Find FLEXnet licensing service.
4: Right click on it and press propoties.
5: Make the start-up type Automatic.
6: Under “service Status”, press start.
Your 3ds max should now work fine. The way I have found this out was when I used to use 3ds max 9 32-bit, the licensing service sometimes became disabled so I had to change it like that. From previous comments talking about FLEXnet, i saw that in services.msc and fixed it.
Hope this helps! Chris

I installed the Education Suite for Entertainment Creation 2011 as stand-alone license with serial and key under Windows 7/64bit (completely new) and I’m getting the error 20 too. I tried every solution in this thread - nothing worked for me. Does anybody know a different way to solve this problem? Thank you for your time!
(Windows Vista and Mac® Boot Camp® operating systems only) A valid license cannot be obtained by the network client when the client and server are on the same machine (IPv4).
Workaround: To workaround this issue, do the following:
Obtain the IP address of the machine. (You can obtain it using the ipconfig command or with the the “System setting” of LMTOOLS.)
Open the hosts file which is located on C:\Windows\System32\drivers\etc folder.
Add the IP address and hostname to the hosts file, such as “10.148.220.50 ACRDLICENSEQA1”
Save the hosts file.
You can now obtain a valid license.
It worked fine for me, you just have to add a line to the hosts file with you info on ip adress *ipv4* and hostname of your computer. My machine was the host of the Network license and I also use max on the same computer, so I need to do that, hope it will help
I have the same problem but with Maya 2011 64bit standalone. I have tried everything on this forum with no success. Initially I was getting error 20, now I am getting error 41. Maya quit working after I upgraded my motherboard. Any other thoughts or solutions to this problem?
Post in the appropriate Maya forum - this one is Max specific.
