That is very unusual and the 1st time that I have heard of this happening. I would recommend that you uninstall the PowerServer Toolkit that should be listed in the installed applications under your MS-Windows control panel. Then, run just the PowerServer Toolkit install from either your PB 2017 Universal installation or your PowerServer 2017 install to recreate the toolkit properly within your PB 2017 IDE environment. Then reapply the appropriate toolkit maintenance.
Note1: Do not try and mix & match the Toolkit installation from both PB 2017 Universal and PowerServer 2017. The toolkit is present within both installs. However, Appeon designed it to be installed using either PB 2017 Universal or PS 2017 - not both.
Note2: Also make sure that if you installed the toolkit via PS 2017 that you do not apply the PB 2017 (build 1689) MR.
