Do you have the SDK stuff on the menu bar.
In older versions, when installing. One used to get an option for Full install, or compact install. (or some words like that). If I remember correctly, if the full install was not done, the SDK stuff was not installed. But I don't know what other things were left out. I always did a full install. I just checked windows Xp, Win 7 and Win 10. all show the part tree palette.
Maybe time for a clean install.
Hello again Andy,
I "think" I may have figured out what's wrong.
I'm installing v11 Pro on windows10.
It seems windows10 does not want to install certain options even though they are selected in the Install dialog.
On Windows 7 it seems to work fine.
I may play around with the Administrative rights and Compatibility.
But it may be that I need a Windows 7 machine to get the tool pallette to work.
Oddly, other than that, everything else seems to work (No SDK), but I can design drawings just fine.
