I downloaded the Neutralhazer demo version, and the install program error message says "No Photoshop installation found in the system."
I downloaded the Mac version. I am running OS X 10.7.3. I have Autopano Pro 2.5.2 installed, and I have Photoshop Elements 10.0 installed and open. I purchased Photoshop Elements from the Apple App store, instead of installing from CD.
