cannot print. get message about printisolationproxy.dll not designed to run on windows or it contains an error. have tried many things to fix it. also all my printers are uninstalled and will not reinstall. have gone back as far as I could but cannot go back before the problem.
More information is needed to suggest solutions.
Explain the fixes you tried?
When the problem started happening?
What printer are you trying to install?
How are you trying to connect? USB or wireless?
What version of Windows do you have?
