Fix Pack 5 also updates the embedded Notes/Domino JVM to 1.6 SR16 FP15 to address security vulnerabilities (technote 1971361)
Subject: Fix Pack 5
FP5 inicorporates all of the previouse Hot Fixes and Interim Fixes, But you must remove any Hot Fixes previously installed prior to installing FP5.
Subject: Remove HF71?
It’s generally been my experience that one needs to remove any hotfixes before installing a later Fixpack.
Have you tried removing HF71 first?
Subject: Buggy fix pack installer
Unfortunately it doesn’t seem to recognize all of the previous hotfixes:
This Incremental Installer can only be used with a properly installed
Domino installation.
Not valid Domino version was detected:
901FP4HF71
That was as patched by https://www-304.ibm.com/support/docview.wss?uid=swg21657963 https://www-304.ibm.com/support/docview.wss?uid=swg21657963
Subject: Yet is installs fine over IF3
Is that IF1? I had 9.0.1 FP4 IF3 installed and and FP5 install worked fine. IBM really need to get this stuff fixed. It should just work and if it needs to uninstall any IF or Hotfix, it should do so.
However on my Notes client with IF2 installed it failed.
