If you have copy and pasted a number into the helper file, especially from the web, it might have non-printable characters in it. Please attach the file "xyz".

I don't think this has anything to do with Intel vs AMD. Clearly, PFGW is not recognizing the big helper. Possibly some corruption due to line endings or "invisible" characters or some such?

Delete the helper file and create new one (preferably using something other than Notepad) and try again?

Try pfgw64 -N -tc -hhelper -x1994 cousin.in
The message might reappear with bigger numbers. Just follow the instructions until you get a proof or an error

Please attach your helper file for inspection.

Use the forum's paperclip.

Uh-oh, it starts with  (0xEF, 0xBB, 0xBF), which is the UTF byte order mark, if you open it in a Hex Editor. This might very well be a problem.

Thanks

Code:
head -n1 Downloads/helper.ini | wc
      1       1      21
Whereas 520461*2^55931+1 has 16+2 characters if Windows. Did you copy this number from the net?

Code:
cat -A Downloads/helper.ini 
M-oM-;M-?520461*2^55931+1^M$
2584831267^M$
