I just installed the Kies package (Kies_2.5.0.12114_1_17.exe) downloaded from Samsung last week. I installed it on a Windows 8 system that was clean. There was no MASetupCleaner.EXE on the system.
After completing the Kies installation MASetupCleaner.EXE did show up in the Windows/WOW64 folder. It had a date of 11/28/2012. There were several other programs that were also installed in that folder with the same date. I did a system restart at this
time and rechecked. They were still there.
Next using the control panel, I performed an uninstall of Kies hoping to see that the programs that Kies installed were gone. No such luck, they are still there.
I then did another restart which resulted in a message that sais "do you want this program to make changes to your system" Yes or No. while getting a pen and pencil the message went away.
I then did another restart which failed and required a second try which worked.
Bottom line, I believe this Keis software is a problem and should not be installed. I will call Samsung on Monday to find out more. The Software that is the problem is created by MarkAny Inc. Info can be found by right clicking on the properties of related
files and looking at the details.
