The box Reads Autodesk Inventor Series 11
Go to Help>About Inventor Product Information
That's not Inventor 11, you have Inventor 2011 series, find the correct SPs' for Inventor 2011.
Latest SP's for Inventor 2011 is SP2, there are a couple of hot-fixes, but no SP3 and SP4. These are only for Inventor 11.
According to the website, listed under Inventor Series 11, Both SP3 and SP4 are listed.
The Readme file for SP 3 reads as follows:
You must install Autodesk Inventor 11, Service Pack 1, andService Pack 2 before you can install Autodesk Inventor 11 Service Pack 3. This service pack updates Autodesk Inventor Series 11 and Autodesk Inventor Professional 11 for all languages.
You are using Inventor 2011. This is NOT the same product as Inventor 11 hence why you can not install the service packs in your link (Inventor 11 would have been called Inventor 2007 if Autodesk have change the naming scheme a year earlier).
You stated you have this:
Build: 553, Release: 2011 SR SP2 - Date: Fri 04/29/2011
This is Inventor 2011, not Inventor 11. Trying to install a SP for the wrong version of Inventor will never work.
Inventor 11 was released in 2006, which you are not running.
Here is what I know. The Box is labeled "Autodesk Inventor Series 11" The install disks are also labeled "Autodesk Inventor Series 11" . I have been on Inventor since Release 1 beta and am the only user here. I have every version released since. Due to rough economy we discontinued subscription after receiving Series 11. The first 2 SP's were downloaded and installed under the " Inventor Series 11" section of Downloads and service packs. Sevice packs 3 and 4 are listed there as well and the readme specifies Inventor Series 11.
Put yourself in my shoes.........
Build: 553, Release: 2011 SR SP2 - Date: Fri 04/29/2011 is what is shown on your Inventor session from your earlier post.
This build is Inventor 2011 with Service pack 2 and the Subscription bonus pack from the subscription website installed. You may well have a box on the desk that says 'Autodesk Inventor Series 11' but that is NOT what is this build is.
I thought from Inventor 2010 boxes had to be requested otherwise the delivery was by download from the subscription site. Maybe the version on your PC was a download rather than the box on the desk ?
How many other versions of Inventor are installed on your PC ? Maybe the 2 sevice packs for Inventor 11 installed because it is still installed on the machine but no longer in use ?
