There are several blogs online detailing this current issue with Vault, so thanks Scott and Dave for taking the time to blog it. None of this work is my own – just paying it forward, as it helped me with my Windows 7 machine – it’s not just a Windows 10 issue.
To get Vault started, navigate to this location:
C:\Program Files\Common Files\Autodesk Shared\CLM\V3\MSVC14\resources\adlm folder
Copy the folder called ‘en-US’, paste it in the same location, and rename it to ‘en-GB’.
Vault should start as normal. Phew!
