make it easy in wn10 to install
We are so sorry for the inconvenience.
When you download and install Glary Utilities, please stop running any antivirus software for a monent.
Please try to uninstall the current version on your pc. Please make sure all the files under “C:\Program Files\Glary Utilities 5” are deleted. Then restart the PC.
Then download and install a new copy of our program(not the previous one saved on your pc). That may solve this problem.
GU5 version download link：http://download.glarysoft.com/gu5setup.exe
Or GU5 Pro version download link：http://download.glarysoft.com/gup5setup.exe
By the way, what is your Operating System: WIN10 32 bit or 64 bit?
If you meet any problem when you install or use it, screenshots would also be very helpful to understand the problem at a glance. Thanks.
