How to remove ddm.exe with SCCM?

Question

Hello, I am trying to create a package for DDM (Dell Display Manager) 2 with SCCM. Today most of our users have DDM1, so naturally I want to remove that version before DDM 2 is installed. However, no matter what I try ddm.exe is not removed (the actual .exe file in the \program files (x86)\Dell\Dell Display Manager\ folder). I've tried superseding, I've tried deploying with a dependency that runs a batch script to remove it. With the scripts I've tried both running the uninstall file as well as just plain deleting all files in the folder (both first closing ddm.exe in task manager). But no matter what I try the ddm.exe file is still there in the end. Anyone else been in this situation? How did you solve this? In advance, thank you.

For information in case others get the same problem.

We finally solved this by using a Task Sequence. I ran 4 command lines followed by a application install.

The lines were as following.

1: Task kill ddm.exe

2: Run uninst000.exe (If present)

3: If DDM.exe is present but uninst000.exe is not, then rmdir the Dell folder.

4: Remove EnTech from HKEY_Users (If present). This last step is to keep DDM2 from asking you to uninstall a older versjon of DDM.

All command lines were run with a IT Administrator account rather than relying on anything built in.
