Hi,
The new RAD Studio 11.2 is binary compatible with 11.1 and 11.0. As such CodeSite 5.4 will compile just fine in 11.2. However, in 11.2 ASLR (Address Space Layout Randomization) is enabled by default for 64-bit apps. Unfortunately, there is an issue in CodeSite 5.4 that prevents CodeSite from working properly under these conditions.
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.
