I uninstalled and then downloaded the install exe. I see it was still version .15. option/u discovered a new version but still the same problem I was able to update tcc ok with .16

I'm getting good at reconfiguring everything.exe. I thought I was being smart and copied the everything.ini to another directory and then to copy it back again when the .ini gets overwritten. Didn't work.
