Do you mean first install your 3.41.10 patched version including dll and license.
And then only delete the folder Rheingold and copy new Rheingold 3.41.30 Folder to programm files?
Or dou you mean deinstall 3.41.10 and copy new one to programm files.
I tryed different ways but don t work good, only main page is shown but cannot search for vin or anything else.

1. Install 3.41.10 and install the patch. Run it and make sure it loads up correctly. Then close it.

2. Right click on "Rheingold_41.30.part1.exe" and run as administrator (will take a while to start). Install wizard should then start (is in Russian but it should be easy to follow).

3. Browse and change install path to c:\program files(x86)

4. Overwrite existing files when prompted (yes to all - top middle button).

Works. Tested ok with k+dcan.
