I upgraded and installed today on 2 computers and have the same problem on both of them.
The 32bit version runs just fine on bot computers.
Now, I am assuming that in order to run the 64bit version you have to launch bbw64.exe in the BB Directory.
On both computers I get the following message after the splash screen.
Range Check Error and on the top line of the error message box I get Band-in-a-Box - NONAME.SG1
Running Windows Pro build 1803 on both my HP Intel laptop and my ASUS AMD desktop. This OS is NOT the latest bug-filled version from MS, but the previous one.
Been working on and building computers since 1979 so I do know what to look for but there is always something new to learn.
Running bbw64.exe as Administrator and so on bla bla bla.
Anyone else have the same problem?
Same problem on my machine. However, for what its worth, after you clear the error messages, BIAB appears to run normally.
