Display Content Type in Forms Designer for Office 365

[RMIC]

Hi,

I work with the Forms Designer in Office 365.

I would like to create the forms within a library with multiple content types.
Now my problem:
Forms Designer does not display the column for selecting the content type. I want to change the content type on the forms.
Is this not available in Forms Designer for Office 365?

Many Thanks!

Small addition: within the Forms Designer dont displayed the column content type

Hi,
The Content Type field is available but only in the designer for windows. We stopped updating the Silverlight plug-in, so if you continue using it, you will not get new features.

Ok, I understand you. Thank you.

If I use the Designer for Windows, I can not log in.
It is an Office 365 environment of a customer. On their site collection I have full access. External users are enabled. My email address is in the Microsoft account system. I have the correct .Net version.

These errors occur:

Sign in failed: The username argument is invalid

Sign in failed: The Remoteserver returned an error: (403) is not allowed

Could you provide a screenshot with your inputs?

The Web URL field is: https://URL.com/sites/name_of_websitecollection

I have looked again because of .Net version.
I have the 4.0: see picture


If I want to install the 4.5, however, comes the .Net Framework 4.5 already part of the operating system is. So I can not install it.

Could you open the site in your browser and expand 'My account' menu by clicking your name in the upper-right corner? Make a screenshot and attach to the thread.

Do you have site collection admin permissions?
What about internal users: are they able to connection from the designer?
