I have migrated my application code and created an executable.
While login in, I am getting below error message:-

 "Error loading client library DLLs. Unable to connect to server".


Thanks in Advance

Hi Ankush; When you deploy your PB App's, you also need to deploy PB's db driver plus you'll need to install your DBMS's db client drivers as well. The message your receiving sounds like your missing the DBMS db client drivers. That is what PB's db driver would be trying to communicate with. Regards ... Chris
Hi Chris,

I tried it on my machine, where I have all the DLL's.

I also used Appeon's "Powerbuilder Runtime Manager" and has copied all the DLL's to below location:- 

C:\Program Files (x86)\Appeon\Shared\Powerbuilder

​After which, I am getting an error message as "LOGIN FAILED".
