Pre-installed Prince not working on Windows

[branets-dasha]

I need a specific older version of Prince, so I installed it on my Windows machine and added its location to PATH:

c:\Program Files (x86)\Prince\engine\bin

npm install detects that Prince is installed and does not download a local version. But when actually running the app, it's not found:

Error: Prince#execute: cannot resolve binary "prince" to a filesystem path

I think it may be due to findInPath() trying to find c:\Program Files (x86)\Prince\engine\bin\prince instead of c:\Program Files (x86)\Prince\engine\bin\prince.exe
