Thanks Union_Thug (& yes these steps have all been implemented using Admin permissions)
I went thru the article and steps
I confirmed the Windows Installer engine is functioning
I confirmed that the Windows Installer is not set to disabled
It is set to manual and I was also able to start the service
I upgraded Windows Installer from 3.something to 4.5
I unregistered and reregisted Windows Installer engine
No Change in system's inability to run SETUP.exe applications has been experienced
Windows installer appears to be functioning but something is preventing any program named "Setup" from running
If the file is called INSTALL.exe, it will run. But any file named SETUP.exe will not run.
I tried the suggestion to run msconfig, turn off all load startup items and non-microsoft services.
I do note that if I attempt to run a SETUP.exe in safe mode, the setup application at least begins to run, but then shuts down with an error:
"Error 1719. Windows Installer service could not be accessed. Contact your support personnel to verify that it is properly registered and enabled."
This I assume is due to being in safe mode. Services.msc Windows Installer START produces an error stating that Windows Installer cannot be run in safe mode.
So, what ever is preventing programs named: "setup.exe" from running, appears to be disabled in safe mode
This is looking more like a malicious code rather than a malfunctioning component.
PS: I attemted to try commandline install via msiexec to see if I could get a verbose log to provide assistance, but I don't seem to have enough knowledge of the syntax.
Any recommendations are welcome.
