Compiling Sample Projects Using Origin Professional 5.0 - LABUTIL.DLLSince Origin has not had a LABUTIL.DLL since version 4.0 I am guessing that you upgraded from 3.x or 4.0 and tried to move your source code into 5.0.
In place of linking to LABUTIL.DLL, you should be using one of the following:
Origin VersionDLL Name Origin 4.1 16 bitO16UTL41.DLL Origin 4.1 32 bitO32UTL41.DLL Origin 5.0 NOTE 1OUTL50.DLL NOTE 1 : Origin 5.0 is only available in a 32 bit version.
While the internal names still begin with LABUTIL_, these functions are in version-specific DLLs.
