IIS Installation don't work

Hi

After a while I come back to InvoicePlane and two years after I can’t succeed to make the install starting on IIS8 (Windows 2012 R2).
I just read some topics about this, I tried to follow but all fails in a “digest” behavior that I can’t overpass.
I just remember that two years ago I have no issue to make InvoicePlane to work.
Have anyone a working experience with it on IIS?

Thnx
