HOWTO: Installing Delphi 7 Pro after the Trial

I had some problems and would like to share the solutions:

if you installed the trial edition and bought a Pack afterwards you need
to do this before you install the Pack:
- un-install Delphi 7 Trial with
C:\Program Files\Borland\Delphi7\BorlandDelphi7.msi
- remove the reg107.txt file in C:\Documents and Settings\yournamehere
- remove the .borland directory in the same place

then you can happily install your new and fully functional Delpi 7.

Have fun and use the CLX for linux-compatibility.
