A VB project builds without errors on its original 32 bit platform but gives these 2 errors and 3 warnings after changing the CPU to x64. Why would this be?

[pre]Severity Code Description Project File Line Suppression State

OK, resolved. Seemed to be because the dlls BarcodeLib and DesktopSerialIO needed to be copied into different locations in Windows for 64 bit.
