First i want to say that i do not own this guide nor i found this out.
The original threat can be found here.
This is pretty much a copy and past of the original threat but this is some
pretty nice information for someone that does not have the needed space
to bot with serval accounts.
I DO NOT TAKE CREDITS FOR THIS THREAT.
1. Open diablo III install location (Windows 7: C:/Program Files/Diablo III)
2. Right click .agent.db -> Open with...
3. Select program from list, select Notepad
4. Locate:
"supports_multibox" : false,
5. Change to:
"supports_multibox" : true,
6. File -> Save
7. Viola
What I added after doing the above was:
On the shortcut to D3
right-click->Properties
add a space and then -launch after the quotes in the target line
Mine looks like "C:\Program Files (x86)\Diablo III\Diablo III.exe" -launch
Note the space between " and -
This prevents an update from "repairing" what we just did.
Some may have to (I personally did not)
8. Go to C:\ProgramData\Battle.net
9. remove directory Agent
Not the start in line.
Please dont forget the space :-)
Note: If you cannot get this to work simply copying and pasting the whole D3 folder (with game closed) so that the new copy has a different name will work. You must create a shortcut for the 2nd folder as the default one will still point to the original installation.
