Robert,I decided to reinstall the runtime module using C:\Program Files (Custom install) to solve the problems I reported in my previous message. But now I receive this message at the same point (step 13):C:\Program Files\ObjREXX>rexx makebats.rex Created C:\PROGRA~1\ObjREXX\SW.BAT Created C:\PROGRA~1\ObjREXX\W2.BAT 1 archivos copiados Created C:\PROGRA~1\ObjREXX\W2WIN.BAT Sw.bat Properties not found - Aborting "1 archivos copiados" is "1 File copied" in English. Any suggestion?
