I am going to update my Dietrichs - I have v.6.02, but I am going to update it with new modules, and higher level on existing modules.
Earlier I have found that to get the same "program" as before (t.ex. when I installed it on my laptop - the only thing that is necessary to copy from one computer to another is the HRB-folder. Now I am used to have both project and HRB folder outside of the Dietrichs installation folders on the C-drive. Now I have them in different folders maybe on another drive. Then I just change settings / paths in the new installation.
I think I could do the same here. But I am not sure what is the best - parallel installation or update??
