Just did the upgrade from existing ETKA7.5 plus to ETKA8.0 according to the instructions from planet-fireball. But I started - as others did too - right with the ETKA8-upgrade-exe file, because I already had 7.5 plus with the latest updates installed.
First it didn't work out: The exe-file copied the necessary updates (vw: 1186,...) to the update-folders, but then version 8.0 was not installed. I tried it many times, but it always failed (including a bluescreen ).
But then I noticed one point : There is a folder called "VIII" in C:/ETKA/PROG, where in my case only 1 file was present. I was remembering, that I had made a copy of all my installation on an external drive a few weeks ago. So I was looking, how this folder "VIII" looked like on the external drive, and there were MANY files in that folder! So I copied all that files (which were a few weeks old) to my C:/ETKA/PROG/VIII and then started the upgrade-file from planet-fireball. And what can I say: It worked perfect and smothly. No idea, if this will help anyone, but let's give it a try!
@planet-fireball: Thanks a lot for sharing with us !!!
