Of course man. As admin and AV disabled. I even know what files are not found are from these lines of your .bat script: if exist Step1_result.png move /y SLIC_result1.png "%desktop%\" >nul if exist Step2_result.png move /y SLIC_result2.png "%desktop%\" >nul SLIC_results1.png and SLIC_result2.png are missing in archive. And they are not generated. UPDATE: Serg, my apologies. My Slic_tool gave me "Dump Error ! (RSD PTR Not found ! )" and 2 missing files and 2 warnings from running of your tool gave me feeling that nothing has worked. That was newbie's mistake. Next I checked that most important parts of your tool ran well despite of warnings and missing files. So I tried to install cert and key. And my Win7 now activated. Sorry for all that. I was a bit nervous considering all the errors and that I'm doing it first time. And THANK YOU for all your work you are keep doing! P.S. Last question - slic is installed permanently in BIOS? If I will choose reset my bios to default settings (hopefully not, but who knows) will it stay?
