D4:pb installshield ask files datapump.exe .hlp .cnt

Why installshield ask me files DATAPUMP.* witch are nowhere?
The program was created with D3 and recompiled with D4.
Install does dot work, on another computer i get an error $3E06 (language
not found)
Databases are paradox.
I have tried to copy all files i have on my directory BDE but il still does
not work.
On my computer it works well.
What is missing on new computer?
