i keep getting error code 126, meaning the psinetr.dll code is missing, tried copying from old files to the 2018 file, still get error. did the same copy/paste with the InerClnt.dll file, which states there is not connection to the internet. checked and Internet is up and working everywhere else. Went to My Account in Pro Series and cannot reload the 2018 package. These where all the prior answers to correct error 126, cannot seem to get past the error.
I would delete PS2019. Reboot. Install PS2019. There seems to have been several errors in the installation process.
P.S. You did not select ProConnect ProSeries as your product. Your post seems to be for the online version PTO.
