"Invalid EurekaLog configuration found" error

Users of recent EurekaLog versions could receive the "Invalid EurekaLog configuration found" error message when they run their EurekaLog-enabled applications. The message looks like this:

Invalid EurekaLog configuration found.

Exception from the following module:
full-file-name-to-your-EXE-or-DLL
was catched in the following module:
full-file-name-to-your-DLL-or-EXE
Both modules have EurekaLog enabled, but EurekaLog code is not shared.

This is essentially the same error as:
- "Can''t assign a TFont to a TFont";
- "Invalid class typecast";
- reInvalidCast;
- "Run-time error 10".
etc.

Possible solutions:
- Do not allow exceptions from one module escape into another (recommended)
- Compile DLLs with Lightweight DLL profile, so your DLL will not have EurekaLog's code
- Compile EXE and DLL with run-time packages, so EXE and DLL will share EurekaLog's code
