When trying to Open files from Vault, you receive this error message preventing you from opening the files.
"The process cannot access the file '<path>\<filename>' because it is being used by another process."
This can occur if a process has locked the local Inventor project file.
Solutions can include:-
Closing the application that may be using the file. It could be Inventor, Inventor Apprentice, Design Assistant, or maybe the Jon Processor client.
Delete the local file mentioned in the dialogue box.
