I can not find these folder or something equivalent in version 2012.
This folder is to locate DOT NET aplications
"Deploy the built files to %programData%\Autodesk\Vault 2012\Extensions\HelloWorldVB
NOTE: The %programData% variable may not be set for all operating systems.
In Windows XP and 2003, this is usually "C:\Documents and Settings\All Users\Application Data".
In Vista and above, this is usually "C:\ProgramData"
The %programData% folder should be there already as part of Windows. The \Autodesk\Vault 2012\Extensions might not be there if this is the first extension. So you will have to create that part.
Thank you very much.
Now i Have this error: "error loading extension hello world" when i try to lauch Vautl Explorer
