A question about lmnewgen.exe(Flexlm)

[ycloud]

...
ENCRYPTION_SEED3 or ENCRYPTION_SEED4 in lm_code.h
are non-unique. Set them to 32-bit values
that you make up, and never change them.
And make sure you keep safe copies.
Exiting.
NMAKE : fatal error U1077: 'lmnewgen.exe' : return code '0x1'
...
This happened when "lmnewgen.exe XXXXXXX.exe -o lm_new.c"
I use the default ENCRYPTION_SEED3 and ENCRYPTION_SEED4.
Vendor key 1-5 and encseed 1-2 found and correct.
I am using Flexlm SDK 8.0c to generate 8.0d licenses,
glseed&val pair already patched.

Now what shall I do?
//thanks
