Hi,

I'm using Powerbuilder 2021.1509.

I have an old 32bit Powerbuilder application that works, it just needs updating. Everything migrated/updated, all looking good as a 32bit. I decided it was time to create a 64bit version to go with the 64bit Windows, uninstalled the runtime and create and installed the new 64bit runtime.  When I tried to open the application, I got the dreaded error message:

The program can't start because atl100.dll is missing from your computer.

This file isn't missing :(

My questions: Where should atl100.dll exist for a 64bit bit powerbuilder application?

The current locations of atl100.dll on my test computer are:

c:\program files\appeon\powerbuilder runtime packager\runtime 21.0.0.1509

c:\program files (x86)\appeon\powerbuilder runtime packager\runtime 21.0.0.1509

Many thanks for your help in advance
