SARscape 4.4.001 is not officially supported on ENVI 5, because it was released significantly before ENVI 5 was ready to be tested with it. But it does seem to be possible to get SARscape 4.4.001 to run on ENVI 5. If you do not have ENVI 4.8, then you will run into problems during installation, when the installer tries to place some *.sav files in the ENVI 4.8 save_add directory. But if you do have ENVI 4.8, then all you need to do is move the SARscape *.sav files from the ENVI 4.8 save_add directory to the corresponding directory under classic ENVI 5, which will be something like C:\Program Files\Exelis\ENVI50\classic\save_add. I just did this, and then was able to import an ALOS PALSAR dataset into SARscape 4.4.001 in classic ENVI 5.0. - Peg
