Symptom

Opening a Version file leads to a warning:
"Neither 'Save' functionality nor procedure execution nor COM available, since max. license size is exceeded"
Can you open version files that exceed the license size?

Resolution

Yes, all license sizes (except of the smalllest) allow to read a Version file containing more network objects than the license allows, but with the functionality limitations the warning describes. Additionally the Graphics tools (e.g. Flow bundle), calculation and changes in the Scenario management are turned off.
Adding of network objects or additively reading of a network file is still possible. You can edit the network manually to underrun the licensed network size again.
