Silent install is working but not visible in Programs and Features

Question

I followed the procedure to silent install SDLTradosStudio2019_SR2_15.2.4.1693.exe using the MSI files but only "SDL TradoS Legacy Compatibility Module" appears in the Programs and Features window. 
 I am missing 
 * SDL WorldServer Components 15.2 
 * SDL Trados Studio 2019 SR2 
 
 If I use the EXE installer, I only miss SDL WorldServer Components 15.2 
 
 However with a previous version SDLTradosStudio2019_SR1_48878.exe this was working perfectly, all 3 components were visible in Programs and features. 
 Anybody seen the same behavior?

Hello Liantis MBSA , 
 I think it would be best to log a support ticket regarding silent installations. 
 The support team can then advise you best-

Found the answer myselve. SDL puts the key "SystemComponent" into the uninstall reg key 
 'HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{898B07E7-A993-4788-BD13-87BF0DAC3CA2}' 'HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{C40000D9-DA97-4748-8174-E102B16ECBE5}' 
 just remove SystemComponent from both keys and the applications become visible.

Hi, We have removed individual msi registration from add remove programs to simplify the uninstall experience. 
 If you need them back you can modify your installation command line for each MSI to unset the property ARPSYSTEMCOMPONENT , then each msi will register itself. So add ARPSYSTEMCOMPONENT= or ARPSYSTEMCOMPONENT=0 to the msi command line.
