UpdateInstaller.exe - where is it?

[spectatorx]

Today i've downloaded wsus offline, by using UpdateGenerator.exe i've downloaded updates and now i wanted to install them but UpdateInstaller.exe is missing, can't find it in wsusoffline folder. To be sure i also downloaded older versions and none of them contain such file.
Did i do something wrong?

This file should be in the client subfolder, paired with an .ini file of the same name.

Check if your AV software keeps deleting the file in question. Some AV are annoying little sneaky bastards!

Or report it as a false positive. This already helped in the past.
