Extract the TP_097.zip file to your PC and edit the package-info.xml file
Find the reference to 1.1 and add ", 1.1.1" after them - should be 2 of them, an install and uninstall
Zip it up again and install.
I had already done this since it's the only file I could find references to 1.1 at all. But since G6 specified *.mod files, I looked through all them first - to no avail of course.
However, thanks for the response and further help.
