Hi I am saving this for future reference. If the Updates in the Native Instruments account do not install correctly try this:
This error is caused by corrupted registry entries/system folders (-> missing msi- files). Please carry out out the following steps in order to fix this issue:
1) Click on Windows Start, type the word “regedit” and press Enter. The Windows Registry Editor should open.
2) In the left-hand browser column choose the following directory
HKEY_CLASSES_ROOT\Installer\Products
3) Press [Ctrl + F] to open the textsearch and enter the name of the product causing the issue (e.g. Absynth) and hit “enter” to search
4) As the first search result a folder in the format
{49AC4825-549F-4C80-8CAE-EE6D550095B1} <-- Example should appear under HKEY_CLASSES_ROOT\Installer\Products\*Folder Product-GUID* 5) Delete this folder (for example: HKEY_CLASSES_ROOT\Installer\Products\{49AC4825-549F-4C80-8CAE-EE6D550095B1} ) 6) Close Windows Registry Editor and run the installer again.
