In order to be able to repair an installed program, WINDOWS stores information in a folder called: C:/ProgramData/Package Cache
In one of more subfolders you will discover current or previous installation CAB files and the Prepar3D.msi. Depending of previous installation you will find File folders in the C:/ProgramData/Package Cache/ that look like folder names as below and contain 10 GB each:
{92B3FF8A-3C33-4EFC-850D-CF29E54292D9}v2.2.10437.0
{92B3FF8A-3C33-4EFC-850D-CF29E54292D9}v2.3.11345.0
{92B3FF8A-3C33-4EFC-850D-CF29E54292D9}v2.5.12942.0
