LabWindows 2006 no ViInt64 ViReal64

So I downloaded some keysight drivers which I am planning on controlling via GPIB.  I am using LabWindows and was not able to build because ViInt64 and ViReal64 are not variable types.  I was able to get it to build by using the following...

//TODO Changed to ViInt32 bit value
//ViStatus _VI_FUNC AgN67xx_viWrite ( ViSession Vi, ViInt64 Count, ViChar Buffer[], ViInt64* ReturnCount );
//ViStatus _VI_FUNC AgN67xx_viRead ( ViSession Vi, ViInt64 BufferSize, ViChar Buffer[], ViInt64* ReturnCount );
ViStatus _VI_FUNC AgN67xx_viWrite ( ViSession Vi, ViInt32 Count, ViChar Buffer[], ViInt32* ReturnCount );
ViStatus _VI_FUNC AgN67xx_viRead ( ViSession Vi, ViInt32 BufferSize, ViChar Buffer[], ViInt32* ReturnCount );

I just replaced the ViInt64's with ViInt32's in the header.  Is this going to cause me a problem?  I'm not sure I even need this functions but they may be used internally in the driver set?

Appreciate your assistance!
