We have InstallShield 2012 Express on a computer since several months.
We change our Internet Provider, we have now a proxy with login
I have internet with the proxy, it's ok
At each start of the software, a window wonder mys proxy logins. If I write my proxy account credentials, it does not work and InstallShield close.
InstallShield is what works behind a proxy?
Is that a port be opened to establish this license verification?

Thanks to help me.
