Well, things have not gone well.
I'm done trying to make this work. Spent several hours on it today, again.
I have been able to install SHIII (repeatedly). Have also been able to get LSH 2015 to install.
Prior to the install of LSH 2015 I could launch SHIII. After the install of LSH 2015 when I attempt launch SHIII (as per the tutorials from TheBerbster) I get the an error message from Windows saying that the application has encountered a problem. This is after following The Berbster's tutorials exactly (I'm not attaching any blame to him, none whatsoever!).
I thought it might have been AVG causing the problem. During the installations, I had AVG disabled. After the installation, I re-enabled AVG but kept getting warning messages about an LSH exe file. So, I deleted AVG, deleted my SHIII/LSH files and reinstalled all the SHIII/LSH files again.
Same result - the same error message from Windows.
I'm sure this is a wonderful mod and my salute
to all those who have created it. Also a salute and a pint or three to those who have posted here offering advice
Good hunting, Kameraden
