InfoMaker is trying to find the imstylecomtemp125.pbl under C:\Users\Public\Public Documents\Sybase\InfoMaker 12.5 folder. On Windows xp, win2003, the directory structure would be C:\Documents and Settings\All Users\Documents\Sybase\InfoMaker 12.5.
If you do not have this folder structure, you can create it and then copy the imstylecontemp125.pbl
and imstyletradition125.pbl from the ..Shared\PowerBuilder to the C:\Users\Public\Public Documents\Sybase\InfoMaker 12.5 folder.
