Install WebFOCUS Installer 9.2.1 on RHEL 8. Once the installation is completed, check the folder "ibi/WebFOCUS_WFI/srv". If there are no files installed under SRV and it's empty, the issue may occur due to the absence of specific libraries. Although the system contains updated versions such as libncurses.so.6 and libtinfo.so.6, the server requires version libncurses.so.5.

To resolve this issue, follow the below steps:

1. While installing WFI, open a duplicate session.
2. Navigate to the directory /tmp where temporary WebFOCUS files are stored. Find the file with a random number, for example, (random_number).tmp file, and access the directory wfsrv.
3. Copy this file to your home directory using the command: cp -r wfsrv ~ (home directory).
4. Open the wfsrv directory and execute the ./isetup file to identify any missing files.
5. Change directory to /usr/lib64, where all system libraries are located.
6. Verify the presence of libncurses.so.6.2 libraries. However, note that the reporting server requires version libncurses.so.5.
7. Utilize the ln command to create symbolic links to existing files.
8. For example, execute the command: sudo ln -s libncurses.so.6.2 libncurses.so.5 within the /usr/lib64 directory.
9. Repeat this process for all the absent files. Once all errors are addressed, the installation window will become accessible.
