Question / Problem:
When attempting to install KTM 6.2, the following error is encountered:
There is a problem with the Windows Installer package. A Program required for this install to complete could not be run.
Answer / Solution:
You can run Microsoft Process Monitor during this process and then evaluate the ProcMon trace for permissions issue or other processes that may be interfering.
In one case we found a process called CylanceSvc.exe
This is an Anti-virus type program that can interfere with the installation process.
Disabling this process and then trying the install again was successful.
