Changing System SID without sysprep

Hi All
Would you tell me why SIDCHG is not working in Windows 8.1 enterprise 32bit and 64bit. Where I can find the command line SIDCHG to change system Identification. We tried this before joining to domain as we capture image and installed and we tried user command line SIDCHG but this is not working can you please highlight what needs to be done in order to run this command sidchg for 32 bit and sidchg64 for 64bit.
This was working fine in Windows 7 enterprise 32 and 64bit.

Thanks

Did you purchase the tool, or are you still using the trial?

perhaps the author has some silent deactivation code built it?

Hi hydranix
We purchased for windows 7 three years back. This still working in Win7 enterprise 32bit and 64bit but not working in Windows 8.1 Enterprise 32bit and 64bit

Yes SIDCHG is from Stratesave site
