The answer to your question is NO.

If the GRC.DAT file is copied to the wrong folder it will not work.

My sample script copies files based on the NAV CE 7.0x model. You can easily adapt it to both find out your version and copy to the correct location based upon your findings.

If you need help let me know, but should be pretty easy. Do a ReadValue on the Registry to determine version, then copy accordingly.

HTH...
