Can you email me your IPT file. I can take a look and see why its crashing. If you open the IPT stand-alone, can you open it? If not, its probably not related to this hotfix and could be some other issue.
You can reach me at sundarsATautodeskDOTcom.
I got your file and can open it fine in R2012 SP1. The crash is most likely not related to this hotfix or R2012 SP1, but perhaps due to outdated graphics drivers or anti-virus or some other issue which is preventing the software from working normally.
Could you please try updating your graphics card drivers and let me know what you find.
Are you using and shadows or realistic visual styles as your default appliation options? I have found that on occasion with the application settings set a specified way that it will corrupt my user profile and the only way to fix Inventor is to delete my user profile with an admin account and then recreate it.
Updating the ATI graphics card with the most current version was the key. Seems to have settled the CRASH bug for good. I will know after I stretch it's legs for a while.
First of all, sorry for my english.. I have crashes all the time with Inventor Professional 2012 64-bit, if i want to open a larger assembly. Will be the problem, that my computer isn't good? The workstations in my workplace are worse, and they can open it.
OS: Windows 7 Ultimate 64bit
MB: ASUS M4A79XTD EVO
CPU: AMD Phenom X4 955 Quad Core 3.2 GHz
VGA: ASUS Radeon HD 6870
RAM: Kingmax 4GB 1333MHz (i know that this is few, but the workstations have 3,5 only..)
HDD: WD 1TB 7200rpm SATA
sorry if you already checked this but,
just firstly make sure that you have the latest service pack for your version of inventor and update your graphics card drivers at the same time.
then see how it goes.
