DLL missing when installing a package (Delphi XE8)

I am migrating from Delphi XE2 to XE8
After compiling one of my own packages, I tried to install it
I get the error (I translate from french) : impossible to start the program because jastay.dll is missing on your computer.
That DLL is one of mine as well.
What shall I do (reference it ? copy it somewhere ?) to have to installation of the package OK ?

Dll should be somewhere in windows search path. Best is in your app folder. But, in XEx this is one of Debug or Release folders (when compile/run from Delphi) - not in app source folder. Go and search for exe.

Well, this is a package I wrote
I compile it, result (bpl) in its source directory
I put the jastay.dll there as well but when installing it, it still fails
In which Delphi XE8 directory should I put the dll ?
Sinisa VukSoftware architectCommented:
Your package call these dll? Did you link it statically?

Best position is windows/system32 folder in this case.

Thanks, I adapted the "path", pointing where the DLL is located and it works
