When I open up Inventor 2014 the Vault tab is visible in the ribbon; however, when I create a new file (of any type) the vault tab disappears from the ribbon. I can retrieve it by right clicking on the ribbon, clicking ribbon appearance and selecting reset ribbon. This fix is only temporary because if I close out Inventor and re-open it I must go through the same steps to retrieve the Vault tab in the ribbon. Does anyone know a way to make it stay in the ribbon so I don't have to reset the ribbon every time?
UPDATE: After digging a bit more I came across the answer: http://www.inventortales.com/2013/05/autodesk-vault-ribbon-disappears-when.html
Worked for me too
It was driving me nuts
Out of the 32 machines I installed Inventor on mine was the only one to have this issue
