searching for 2 files

I was onsite the previous week with a FP customer who will be using the SDK to integrate in with their internally developed sales app.

 

 

I just received an email from my tech contact that the developers are looking for 2 files and can't find them. That's all I know at this point. The files are

 

APPCTRLLib and AxAPPCTRLLib , both .dll's I'm assuming.

 

 

Any nudges in the right direction would be fantastic.

 

 

Thanks!
