When you install Vault Server you can get this error

In the Autodesk Vault x 201x(Server) install.log file, if you search for "return value 3" (a value indicating an install error in and MSI log file), immediately before that value you will see this message...
MSI (s) (AC!E8) [11:11:24:450]: Product: Autodesk Vault Collaboration 2012 (Server) -- 1: 5 2: adlmPITSetProductInformation failed. 3: 13
CustomAction adlmInstSetProductInformation returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
This happens because the wrong Product Key was entered.
You can obtain the correct Product Key by navigating to the root folder of the Vault Server installation. In there will be a file called MID*.txt (* because it differs depending on the version of Vault). If you open the file in Notepad you will see the following
MID: VLTC_SERVER_2012_64/32bit_EN_RTM
Product Name: Autodesk Vault Collaboration Server 2012
Platform: Windows XP/VISTA/Win7 / Windows Server 2003/2008

The Product Key is the first five digits of the Part Numebr highlighted above. If you use this, you should be able to get past this error.
