Recently Oracle has released a patch for OBIEE 188.8.131.52.0 to upgrade to 184.108.40.206.2 with the major bug fixes. But once we upgrade the RPD version raises to 220.127.116.11.2 and then we cannot open this new version RPD from available OBI Client (18.104.22.168.0/22.214.171.124.0) Admin tool.
So we need to download another patch set for Admin tool (in fact, it is a full client tool for 126.96.36.199.2)
Download patch 13794002 from oracle support.
This patch contains a zip file called p13794002_111160_Generic.zip. Unzip this into a directory.
Then navigate to /obiee111162patches/13794002/files/clients/biserver
Here you can see two client tool installers for 32-bit and 64-bit Operating systems. Install them based on your system configurations.
biee_client_install.exe (for 32 bit Operating Systems)
biee_client_install_x64.exe (for 32 bit Operating Systems
