Most, if not all, commercially available Autodesk software uses Microsoft's own MSI (short for Microsoft Installer) as a standard installer technology. Among the many advantages of using this standard installer technology, it also offers verbose log files. In other words, if you encounter an installation error at the end of a long installation, it rolls back and then displays the location of of the setup log files. when you open the log file it can be somewhat daunting to know where to start to look for the cause of the installation failure.
Perhaps one useful skill for troubleshooting installation issues for Vault client and server software, (and indeed any installation issue using the MSI, Inventor, AutoCAD, etc) is the ability to get to the heart of the problem quickly.
Searching the MSI log file in Notepad for "return value 3" will take you to a point in the log file just after the first error. Normally one error causes other errors to follow, so looking at the first one is normally key to solving the problem.
In the following example we were unable to install SQL 2005 SP2 in a Vault 5 to Vault Manufacturing 2010 migration project (migrating via 2009 as migration directly from Vault 5 is not supported ). Searching for "return value 3" in the log file showed that the solution was written in plain English and after following the instructions we were able to install SQL 2005 SP2 and continue the migration project.
