Artformer, it looks like none of us has payed any attention to the log you posted. I can see the directory your install to is - D:\My Files\THE GAME CREATORS\DBPRO FILES\Dark-Basic-Pro-Initial-Files\Dark-Basic-Pro-Initial-Files\Install. I believe the problem is the lack of a registry entry and no FullPath entry in Launch.CFG. Replace the Launch.CFG file in the install directory with this -
Launch.CFG
; Launch Configuration
[LAUNCH PATH]
FullPath=D:\My Files\THE GAME CREATORS\DBPRO FILES\Dark-Basic-Pro-Initial-Files\Dark-Basic-Pro-Initial-Files\Install
[LAUNCH FOLDERS]
Compiler=Compiler
Editor=Editor
Help=Help
Projects=Projects
Temp=Temp
[LAUNCH FILES]
Compiler=DBPCompiler.exe
Editor=EditorNew.exe
Help=main.htm
IntroOn=No
Intro=introduction.htm
Also add a temp folder in the Install directory. Now copy and paste this into notepad and save it as Dark Basic.reg.
Dark Basic.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Dark Basic\Dark Basic Pro]
"INSTALL-PATH"="D:\\My Files\\THE GAME CREATORS\\DBPRO FILES\\Dark-Basic-Pro-Initial-Files\\Dark-Basic-Pro-Initial-Files\\Install"
"INSTALL-FILE"="D:\\My Files\\THE GAME CREATORS\\DBPRO FILES\\Dark-Basic-Pro-Initial-Files\\Dark-Basic-Pro-Initial-Files\\Install\\launch.exe"
"INSTALL-FROM"="C:\\"
"dbpro"="506d61566d80e3d9686315f6cbdafaf8"
After saving the file just click on the file to add DBPro to your registry. This is based on the install directory listed in your post. Hopefully this will work.
