IguanaTex: installation and test

I tried to install IguanaTex on my new laptop but failed. There are two possible problems. The first is that the Temp folder can only be accessed with administrator privilege. The second is that there are packages missing in MikTex, and a pop-up window says "the object is not found". In this later case click the "interactive mode" when using IguanaTex and MikTex should be able to install the missing packages.
