The Updates Have Arrived - Service Pack 2 for Autodesk Inventor 2011

Chaos reigns within.
Reflect, repent, and reboot.
Order shall return.
~Suzie Wagner, 1998

I found out that Service Pack 2 for Autodesk Inventor is out today.  You can download it from the link:  HERE

Installing is usually pretty easy.  But there are a few things to know before you get started.

• There are different Service Packs for 32 bit and 64 bit installations.  Make sure you download the correct one for your operating system
• Autodesk Inventor Service Pack 2 is an "Incremental Update".  Translation:  You'll need to download and install Service Pack 1 before installing Service Pack 2
•  If you've installed the Subscription Advantage Pack, there's a different Service Pack 2 for you.

Don't worry, they're all located at the same link above.  It's just a matter of knowing which one to get.

If you don't know the answer to any of the above questions, you can check at at Help>About Autodesk Inventor

Finding the "About" screen

You'll see this dialog box come up, and this contains a lot of information about Inventor's current "Build". 

Autodesk Inventor information screen.  Note the "64 Bit" & Build Numbers

I've circled the Build Number and 64 Bit areas of my screen.  These are the ones worth noting.

Are you wondering which build number corresponds to which Service Pack level?  Autodesk has a tech document at the link HERE.  It's a great reference to help you out.

 Lastly, if you try to install the service pack, and you get this error:

This isn't as scary as it looks.  Typically, the "Wrong Version" or "Missing Program" the Windows Installer is referring to is caused by one of the following:

• You're trying to install a 32 bit patch to a 64 bit system
• You haven't installed Service Pack 1 yet
• You're trying to install a Subscription Advantage Pack SP2 on a system that doesn't have the Advantage Pack installed, or vice versa.

That's it!  Once you know the tricks, it's pretty straight forward!
