Can no longer cut/paste custom cofiguration files in 2017 any solution
Do you mean custom/configuration properties? If yes then I'm seeing the same behavior. For the moment you may use a macro or the excel file stated in this post: https://forum.solidworks.com/message/663644#comment-663644
I could only find this SPR #: 988295 but not sure if it is related to 2017 or older version.
It's only 2017, 2016 SP5 is OK
Workaround "copy it from one of the files, paste it on a notepad document, then copy it from a notepad document".
This is not resolved in 2017 SP1 E.V.
