Seems odd the originally posted error shows the error in C:Realband\
instead of
C:\Realband_X64\ folder (for both where the error occurred and the application that caused the error)

Just noticing ..
Are you sure you are launching the new RB?
The error (to me) implies you are actually launching an older version
