just installed the Magento Turnkey app, I try to access it via web from the host pc, but I receive this:
Exception printing is disabled by default for security reasons.
Error log record number: 1578685967
Even though it appears the error message is different, it seems like this is the same (or similar problem) that you reported in another post. It probably would've been better to just post again to that topic rather than start another thread (especially considering it seems to be the same or similar issue).
