CC2.28 Custom Locations Error

When I add a custom location for my Firefox based browser, it starts to clean the correct custom location but then after a few steps into it, it crashes with the following error message:

---------------------------

Microsoft Visual C++ Runtime Library

---------------------------

Runtime Error!

Program: G:\utils\CCleaner.exe

R6002

- floating point support not loaded

---------------------------

OK

---------------------------

The Custom location added to ccleaner.ini was

CustomLocation1=FIREFOX|\browser\.default\mozdata\UserData\

I am using relative paths as I am running from a USB drive.
