First of all >> thanks a lot to Ulrich Krause for posting this helpful article.
For some reasons, some customer also have the IBM Notes Client installed on the same server where they run the IBM Domino Server. If you try to install the JVM Patch, the installer always comes back with the directory of the IBM Notes Client and you´re unable to install the JVM patch to the Domino Server.
Regarding the hint of eknori you can do this the following way:
D:\temp\jvmpatch>184.108.40.206_Server_w64_JVM_Patch_20150303_142312.exe LAX_VM d:\domino_program_directory\jvm\bin\java.exe -D$USER_INSTALL_DIR$=d:\domino_program_directory
It´s working great !!! Thanks again !!
