Hi lbsinner,

px.dll is a module associated with Px from Sonic Solutions. Non-system processes like px.dll originate from software you installed on your system.

Hope that answers your question.

Please use these instructions below to completely remove the program.

2. Go to C:\Program Files\Primera Technology. Delete the "PTPublisher" folder
3. Go to C:\Documents and Settings\All Users\Application Data\PTI. Delete the "PTPublisher" folder. (The "Application Data" folder may be a hidden folder)
On Windows Vista and Windows 7 go to C:\ProgramData\PTI. Delete the "PTPublisher" folder.
Do not delete the "Drivers" folder from PTI.
Note: This folder contains your log file and personal settings such as default print quality, burn speeds, and default file locations. If you delete this folder, all settings will be returned to their factory defaults and the log file will be cleared. Rename this folder to "PTPublisherOLD" if you think you may want to retain this information.

set compatibility to windows xp (not essential, i tried this first and the combination worked), will run as normal now!

If the error started appearing soon after you have installed a new application or device driver, then it is possible that the error is occurring due to problems in the installation. To fix the error in this case, uninstall the software you installed and reinstall it.

Many times, errors related to DLL files, such as Msvcr71.dll, occur due to malware infections. Download, install and run Malwarebytes.

Hope this helps.
