Given the slim detail I would not hazard a guess. But if this happened to me I'd be on google with the title that didn't install followed by the error message.
As I have no failed title, I won't do that search but you can.

I use vista home pro 64 bit and I was trying to uninstall a program, but could not because of a message: cannot open installog file. How do I fix this?
