LV 7 to LV2012 64bit

[twrc]

 am upgrading an application from LV 7 to LV2012 64bit on Windows7. I have a problem with one of my VIs (Printer Availability.vi) being converted; it checks if a printer is attached before sending data strings through LPT1. In LV7 the VI used In Port8.vi as a sub vi; after loading the VI into LV2012 In Port 8 was automatically converted to In Port.vi.

In LV7 the In Port 8.vi uses a call library function to call cviVXDWrapper.dll.  In LV 2012 64 bit cviVXDWrapper.dll is not valid; the sub vi does not work because I cannot determine where the correct dll is.

What is the equivalent dll for 64bit platform?

Is there an equivalency list for other common dlls supplied with LabVIEW?

Thanks

Hi twrc,

My name is Humphrey and I am an Applications Engineer at National Instruments.

As described here (http://digital.ni.com/public.nsf/allkb/D198AC61B9D3EAA68625731300743C30) and here (http://digital.ni.com/public.nsf/allkb/2CD299B53987E1D186257921007773F4), the In Port and Out Port VIs are not supported on 64-bit systems due to increased security measures with Windows. This discussion post mentions an alternative (http://forums.ni.com/t5/LabVIEW/Alternative-VIs-for-In-Port-vi-and-Out-Port-vi-for-64-bit/td-p/16072...
