Error loading dll

Hi

 

I'm integrating ProjectWise with Lotus Notes - so far so good.  My code is running well on my machine, however when testing my code on a user's machine and I get the following error "error in loading .dll". 

 

The ProjectWise path is in the "Path" in environment variables (same as on my machine). I'm calling the aaApi_Initialize Lib "DMSCLI.dll" in my code.   Does anyone have any clues? 

 

Many thanks
