Hi,

you tried to install a Software Package and it stops with MSI Error: The System Administrator Has Set Policies to Prevent This Installation

3 possible reasons for this issue:

An previous or uncomplete installation
Check the registry subkeys of HKEY_CLASSES_ROOT\Installer\Products if there is already an entries for your product. If yes delete the whole Subkey.

Check if the Windows Installer is disabled
Look for the key
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer
DisableMSI Type: REG_DWORD
If DisableMSI is set to 1 then the Installer is disabled by a policy (local or domain). Try to set it to 0

Check if any Software restriction policy is active
You can recognize if a Software Restriction Policy is active when an Registrykey
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\safer\codeidentifiers
exists.
Install the Group Policy Managenment Console and examine the Policy.
