I have an older application that I am supporting. The way it is installed currently, we do not lay down either of the Accessibility dlls, and we don't lay down a pb.ini file.
On most PCs where it is installed, we do not see any problem with this. On at least one PC (which happens to be a developer's PC), we see an error dialog pop up, saying: "Error Loading Library. Please check whether PowerBuilder Accessibility library can be located in the path." Once you click OK on this error dialog, everything seems to work fine.
I'm assuming there is something environmental happening where we are seeing this on one machine but not others, but I don't know how to figure out what that is.
