The hotfix from Tracker Software doesn't have the administrative rigths to copy the file, so you have to do it manualy or use a powershell command to copy the file (powershell "saps -filepath %0 -verb runas").
The solution for me was:
32-bit Windows: copy the 32-bit version of the DLL (/W32X86/XPSSVCS.DLL) in this folder: C:\Windows\System32\spool\drivers\W32X86\3
64-bit Windows: copy the 64-bit version of the DLL (/x64/XPSSVCS.DLL) in this folder: C:\Windows\System32\spool\drivers\x64\3
And the hotfix (that didn't work but had the good files), you can find here: http://www.tracker-software.com/knowled ... ot-working
