I have been testing EEPC 5.2.3 in prep for upgrading our 5.1.8 environment. As usual, I build a BartPE disk with WinTech installed to test recovery tools. I noticed that WinTech Help About reports it as version 5.1.7, but if you check the file properties of the executable on the disk, it shows as 5.2.2.
It will be hard for my PC techs to verify they have the latest WinTech! The version deployed with our 5.1.8 rollout is also 5.1.7, but in this case the Help About and file properties match.
