I just changed some contasts to controls in a FPGA base program so it needed to be recompiled. but it after compiling program showed error. An internal software error has occurred. Please contact National Instruments technical support at ni.com/support with the following information:Error 8 occurred at Copy in nicrio_StockOutputVhdlAndInstantiation.vi->nirviGetInstantiation___cRioStock_io.vi->nirviGetInstantiation___nirviEIOImplementation_modGen.vi->nirviGetInstantiation___nirviEIOImplementation_modGen.vi.ProxyCallerPossible reason(s):LabVIEW: File permission error. You do not have the correct permissions for the file.=========================NI-488: DMA hardware error detected.C:\NIFPGA86\clntTmp\TensionCo~65_FPGATarg~A7_FPGABase~A1_eogs1jH0~18\Crio9426IoNode.vhd Can someone state the reasons for which it is showing an error.

Hi, I have a couple of questions, 1. If you change your controls back to constants, do you still get the same behavior? 2. What hardware are you trying to deploy to? If it's a cRIO, have you formatted your controller and reinstalled the proper software to it? 3. I've been doing a little research and it sounds like a possible problem may be with firewall/antivirus. Here is the document that discusses that: http://digital.ni.com/public.nsf/allkb/D8D46FD4DBD1015786257540003B2DC6 Do you have any antivirus installed on the computer? Can you try disabling it and rebuilding the bitfile? Regards,

Solved!

I ran into this issue and was able to solve it by unmarking the folder as read only. Unfortunately you need to use the command line to do that
