I performed a DMA uninstall.
- C:\Skline DataMiner folder was deleted
- C:\Progam Files\Cassandra folder is deleted
- C:\ProgramData\Cassandra folder is deleted
- Cassandra HKEY is delteted with the following: Run regedit as Administrator and delete the registry key “cassandra” in HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Apache Software Foundation\Procrun 2.0
When I do a new install, Cassandra files are not installed. The installation log indicates that Cassandra was detected. I am guessing there is some installation check that thinks the Cassandra db is already installed when it is not actually installed.
I also tried the manual delete instructions.

I had the same problem recently, ended up trawling the registry to find any mentions of Cassandra and removed them.
After that, the install completed correctly

Did you also delete the Cassandra service ? It is mentioned in point 5 in https://docs.dataminer.services/user-guide/Advanced_Functionality/DataMiner_Agents/Uninstalling_a_DataMiner_Agent.html#uninstalling-a-dma-using-a-manual-procedure
