I run installing NVEXPORT as instructed, but an ERROR occurred saying: Cannot open control file “C:\NV2\NVEXPORT.PRC
when I push F1 button a window dialog box open saying: The specified library control file could not be opened for one of the following reasons:
– The control file does not exist
– The specified path is invalid
– Access was denied

I then open drive C and I see there is nothing wrong about it because:
– Folder C:\NV2 is exist
– The file NVEXPORT.PRC is exist
– I have gave permissions to users to allow full control, modify, read & execute NV2 Folder and NVEXPORT.PRC file

Please help me to solve this problem
Many thanks
