We are in QC12.2 and HP Sprinter 12.2 which are compatible.
I have one user who failed loading Sprinter whith or whitout QC.
The screen is stuck written Loading HP ALM file 59/75.
Are other users able to connect from Sprinter to QC from the same machine? Is the user experiencing the problem able to connect to QC from the browser?
Finally, could you please share Sprinter log file "Sprinter.exe.log" from %appdata%\HP\Sprinter\Log\ after reproducing the problem?
