The serial number you have entered is not valid

When you attempt to open the freshly installed software it asks for the serial number of the product. You enter the serial number listed on the back of the product case/box, but it is rejected with the message "The serial number you have entered is not valid". So what's going on?

If this is an older version of AutoCAD/LT, usually when you see that type of error it means that the license has been marked upgraded or returned. To have your license status verified, please contact the Activation and Registration team directly:

1. Visit http://knowledge.autodesk.com/contactus
2. Select “Activation & Registration” or “License Management”
3. Select appropriate subtopics from the pull-down menus
4. Select “I Still Need Help”  if you need personal assistance.

Specifying a different TEMP folder for AutoCAD/LT

AutoCAD/LT defaults to your Windows Log-in Temp folder location for many items (including your Autosave files) it needs to run every time you use the program. While this is convenient to program for the, it becomes difficult for you the end user to find these items when you need them the most.

To access your default Windows TEMP folder, you can either use Windows Explorer to go to the following folder:
C:\Users\YourNameHere\appdata\local\temp\
or Click Start menu (Windows) then Run: In the Run dialog box, enter %TEMP% and click OK.

You can however set up AutoCAD/LT to use any other folder you may have or wish to create: this can me one single folder on your local PC that you can access quickly (in the screenshot example below I use a folder called TEMP located on my computer's C primary drive).

Or you can create multiple folders, one for each of the five categories in the screenshot above, or just one additional folder for your Autosave files for example. After you create one or ore of these folders in Windows Explorer, open OPTIONS command's FILES tab, select the entry you wish to change, select the folder name, tap the BROWSE button and browse to the new folder to select it.Just follow the sequence of numbers in the screenshot below.

You now can easily find your temp files and SV$ extention Autosave files quickly. ◦
