Hi Gordon,
While what I stated earlier is indeed true, we discovered that there was an issue with the CodeSite Logging Classes when ASLR (Address Space Layout Randomization) was enabled. The problem affects 64-bit applications and prevents CodeSite messages from being delivered to the CodeSite Dispatcher. As such, Live Logging and File Logging do not work.
We have just released a new 5.4.1 version that fixes this problem. Please see this link for more details: CodeSite ASLR Support
We have also provided Embarcadero with an update to the CodeSite Express edition that is deployed through the GetIt Package Manager. The new 5.4.1 build should be available in GetIt soon.
