I'm using WiX toolset to create my msi file from a C++ codebase with cmake and cpack. This setup works great for the past 6 months, but now i'm getting sporadic bad behaviour.
My Setup uninstall older products with the same upgrade-code to guarantee that there is only one version of my product installed (always major upgrade). I rolled out the newest version to my users (via SCCM) two days ago and in 10% of all installations I have the following problem.
The uninstall of the old installation seems to be sometimes wrong. The uninstall process remove the files, but left the root directory and the bin directory but all files are removed. When I query for the installation of the old product via WMI it say that it is installed, which is strange. The other 90% of the instllations everything works great. I also can not reproduce that locally.
I have a log file, but i'm not sure if it is from an misbehaving installation or not.
The logfile is very long, so I post only snippets which makes me sceptical.
MSI (s) (0C:9C) [15:21:35:083]: Component: CM_CP_runtime.bin.main2.exe;
Installed: Absent; Request: Null; Action: Null
...
MSI (s) (0C:78) [15:21:43:591]: Executing op: FileCopy(SourceName=-dbqfin2.dll|FreeImage.dll,SourceCabKey=CM_FP_runtime.bin.FreeImage.dll,DestName=FreeImage.dll,Attributes=512,FileSize=6201856,PerTick=65536,,VerifyMedia=1,,,,,CheckCRC=0,Version=3.17.0.0,Language=1033,InstallMode=58982400,,,,,,,)
MSI (s) (0C:78) [15:21:43:591]: File: C:\Program Files\LDS Studio\bin\FreeImage.dll; To be installed; Won't patch; No existing file
The Action: Null means that there is no operation (but it should be local), but I'm not sure why. When I start the installation a second time everything works fine (because there is no old version). I had that behaviour a year ago (but only for two single files) when we are porting from Visual Studio to cmake and forgot to add a version to our dll (previous dll had a version, new one had no version, so msi think that's not a new version and skip it in REINSTALLMODE default mode 'omus'). Since then we have changed nothing and everything works fine until 2 days ago.
Here is my wix_main.wxs file

I've found some blogpost where people deal with the OnlyDetect mode in but I'm not sure if it can help me or not because I'm not able to reproduce it on my machines.
Switching to REINSTALLMODE amus (https://msdn.microsoft.com/en-us/library/windows/desktop/aa371182(v=vs.85).aspx) maybe is my last resort, but that would be my last resort.
I've found this blogpost https://jpassing.com/2007/06/16/where-to-place-removeexistingproducts-in-a-major-msi-upgrade/ => could it be that i have to change from
<RemoveExistingProducts Before='InstallInitialize'>
NOT REMOVE
</RemoveExistingProducts>
to
<RemoveExistingProducts After='InstallInitialize'>
NOT REMOVE
</RemoveExistingProducts>
???
Maybe somebody can help me with the problem
