Hi, I have hit the same problem in one of our hosts, but not in the other, both the same OS version and Oracle 11.1.0.6 so when checked the package SUNWmfrun the following: KO hosts PKGINST: SUNWmfrun NAME: Motif RunTime Kit CATEGORY: system ARCH: sparc VERSION: 2.1.1,REV=10.1999.12.02 OK host PKGINST: SUNWmfrun NAME: Motif RunTime Kit CATEGORY: system ARCH: sparc VERSION: 2.1.2,REV=10.2002.03.13 Our system team has upgrade the package version to 2.1.2 , and runInstaller runs again. Hope it helps you ana
