Hello,

We use Appeon's Packager to build an MSI for deploying PowerBuilder's RunTime for our applications.  For the most part it's working fine with one exception.  After installing the PB RunTime and then installing our applications, we need to copy the libeay32.DLL from C:\Program Files (x86)\Appeon\Shared\PowerBuilder to our applications' install directory.  Each application needs its own copy of the DLL.

I found that this is documented when searching on the internet, but why can't Appeon "find" the DLL on its own.  After all, C:\Program Files (x86)\Appeon\Shared\PowerBuilder is in the path of the machine when the MSI is done.

Just a curiosity, that "bothers" me.

Thank You,

Christopher

If a required file isn't being included by the packager, you should report it as a bug.

It is being included by the MSI and placed in C:\Program Files (x86)\Appeon\Shared\PowerBuilder, as are the rest of the PB RunTime.

However, I then have to copy libeay32.DLL to my application's directory.

For example, if my application's exe and PBD files are located in c:\testProgram, I have to put a copy of libeay32.DLL in c:\testProgram even though there is a copy of it in C:\Program Files (x86)\Appeon\Shared\PowerBuilder and C:\Program Files (x86)\Appeon\Shared\PowerBuilder is in the path.

Hi Chris;

 FYI:  The " libeay32" dll is used for SOAP web service processing.

Hi Chris,



I already knew that the file was part of web service processing, but my question is why does it need to be local. Is it just "that's the way it is and always has been", is the a technical reason, is it just an oversite? Why, not what.



Thank You,

Christopher

Yes, that is very strange. I have lots of Apps that perform SOAP processing and do not require a local copy of that DLL.

What build of PB2017 are you using?

Ok, now that is scary. None of our webServices worked until there was a local copy. We are deployed on PB 2017 R3 1858.
