It appears from the answers to some bug reports that all of msvcp80.dll, msvcp100.dll, msvcr80.dll, msvcr100.dll, atl80.dll and atl100.dll are needed for deployment of PB 2017 apps. All of them are present in the C:\Program Files (x86)\Appeon\Shared\PowerBuilder folder.
I'm just curious about why two versions of each of those Microsoft DLLs are needed. Can someone please explain it? Thanks.
