Hey guys,
I had someone it chat that couldn’t patch out their firmware even following the directions from GHI to the letter. Why? UAC. UAC is the devil; so if you’re running VISTA or Windows 7 do this:
Right-Click TeraTerm, select Run As Administrator
It will now work. 
Have Windows 7 here. Did not run into that issue yet. Wonder what the difference is?
I have UAC turned off. Are there some users who have it running and can confirm (or bust) that UAC is the cause?
UAC is not the problem here folks. I live on UAC, and this has NEVER been an issue, betas and full releases.
I dispute the “devil” statement, but I’ll forgive you once skewworks 
Has this been tested on LIMITED accounts?
