Cassandra db does not install after a DataMiner uninstall and a new install with 10.2

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.

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

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
