I hope I’m not just reposting anything but I have not seen the same issue as I’m having. I downloaded the toolbox and was able to use it yesterday to test the .tif conversion… worked great. This morning it started giving me errors and deactivating the add-on.
Now every time I try to install or activate it I get the message… “An unhandled exception occurred in your application. Contact your administrator or the author of this document for further assistance.”
Tried it on a second computer and it is doing the same thing, but this one didn’t even get one use out of it first.
