Problem:

I get error message saying that installer/uninstaller has detected running EurekaLog instance and asks me to close it before continue with installation/uninstallation. However, I do not see any EurekaLog programs. 

Reason:

There may be hang EurekaLog application that is still running in the background.

Solution:

• Try to find and kill EurekaLog's processes manually.

or

• Restart your computer.
