Running HWiNFO64 v7.30-4870. Purchased a HWiNFO64 Pro Personal license. I followed the instructions to activate the Pro license of HWiNFO64 as shown in the attached .pdf files. I copied the HWiNFO64_KEY.txt file and pasted it into the HWiNFO64 folder where files HWiNFO64.exe, unins000.dat, unins000.exe, HWiNFO64.ini, HWiNFO64_settings.reg, and HWiNFO64.exe shortcut, were installed in F:\XXXXXX\PROGRAM FILES xxxx\HWiNFO64\. I also have complete copies in 2 other locations in F: drive, as internal backup of critical folders, plus external copies as well. I restarted the desktop PC - my build. I still get a notice that the license key is invalid, and if purchased legally, I should contact Support. For what little a Pro Personal license costs, I would purchase again, but do I have to? HWiNFO64 free has for many years, been installed in F: drive.
