Visual Basic, FineReader 5.0 & 8.0 Help !

I have a Visual Basic application that uses FineReader 5.0 as its OCR. I’ve upgraded my FineReader to 8.0, and now my application doesn’t run. It still references a librbrary file called FRENGINE.TLB. My FineReader 5.0 has a verison 5.0 of that file, and I assumed that installing FineReader 8.0 would also make FRENGINE.TLB version 8.0 available. Where can I download a copy of FRENGINE.TLB version 8.0? Help !
