On running new ionic1 project i get error in my gulp file

I downloaded and installed ionic2 project it worked fine but when i run an ionic 1 project i get this error

Not a valid win32 application

Could someone help me to fix this issue, If i download a fresh project in ionic 1&2 everything works fine, but when i try with a old ionic 1 project i get this type of err
