I installed a program called Soluto and every time I open Calibre Soluto "thinks" it crashes. I am working with them to solve their end of the bug. Because Calibre runs just fine. I am running Windows 7 64 bit.
They asked me to send them my Windows Event log, which I did.
My Soluto web page says: Probably caused by
qtcore4.dll
After running for 00:01:12 Exception access violation (c0000005)
My event viewer says:

Yeah, ok, I haven't updated it
