The menu is an object now. You need to find the menu object (normaly in the template content) but it could be on other places as well (page). after finding it double click it to edit.

If the object is too small you will see the hamburger icon in it instead of the actual menu, just make it bigger in that case or doucle click the hamburgermenu

If you can't find it it could also be that there is no menu? Then you need to add it yourself.

I do everything right

And when i clicked twice to edit the menu, the screen turns white.

Hello,

For all purposes:

What is the size of the header? We saw this on the french forum...

If the header is at [0,0] the menu is not visible.

@+, J.P.

The size of the header is 1200 

Hello Valeri Radev P.,

Try to repair the .NET Frameworks by following these steps:

To repair the .NET Frameworks 3.5 and 4 you need as first to use following cleanup tool to remove .NET 4:
http://cid-27e6a35d1a492af7.skydrive.live.com/self.aspx/Blog_Tools/dotnetfx_cleanup_tool.zip
Once done go to Control Panel then choose Programs and Features and then click on Turn Windows features on or off. Clear the check box for Microsoft .NET Framework 3.5.1 and then click on OK. After Windows disables the feature you will need to go back to re-enable Microsoft .NET Framework 3.5.1
This procedure can take some time to deactivate and activate .NET 3.5.1 and once done reinstall .NET 4 after downloading it from following link:
http://www.microsoft.com/en-us/download/details.aspx?id=17718

Once done test it again also on a new project to see if then it appears.

Many thanks!

Firstly, please ensure you have backed up your projects in full to a standalone device (this also applies to anything else of importance to you eg docs, photos, music, email, etc), and if possible create and save an iwzip of each project through export project (step5) then copy it off the PC

Did you do a clean install of Win7 or simply try install over the existing copy?

My sad experience is that these frustrations do not go away unless I do a clean install (wiping out ALL content on the existing HD). If I attempt to keep existing data and installed programs I usually fail to repair the problem because the problem is invariably in the registry.

My experience is Win7 SP1 clean install + updates should give you a smoother run than does Win10

Good luck, please advise if you think we can assist.

Great!

Thanks for the feedback, hopefully this  will help other users as well.
