I had older version 2.5.0 working fantastic. Due to rebuilding of my machine, I have reinstall it - but when I installed the latest version (6.7?) it just hangs and never prints. I was trying to print an excel file into pdf (Which I did before with older version of 5.2.0 and worked very well). The pop-up of "Printing" stays forever and then it says (Not responding) and eventually it crashes the excel as well. So uninstalling it. If I find the older version 5.2.0 - I will try installing it and will see whether it still works else no option but say "good-bye" to pdf24 and use the other old one Primopdf. However I found in past that pdf24 was providing better pdf quality than primopdf. Will try luck once more.
Ugly as pig, when it comes to the UI. Constantly crashes ghostscript executable. Other than that - when it works - it does the job... (Running on a 64bit Win8 PC)
Thanks
