I have experienced the same, on a laptop running 64bit Windows 7. However, the software installed nicely fromt
he same dvd on another laptop running 64bit Windows 7. In this case I'm now certain the problem is
that the first laptop does not have the resources required to run the Canon software (cpu too weak).
The error message "unknown error" is not good software work, the Canon install program ought to
check for such things and report back in case of problems.
Neither is the lack of detail on the G15 package on computer requirements solid work.
The camera itself is excelent.
Via www.canon.com you can find a link to software for G15, which includes more detalied information on computer
requirements.. I have pasted in the text for the ImageBrowser EX below
my writing. Check via "control panel" "system", whether your computer is "big" enough for the software.
Good luck, Henrik
