I removed all the Lexmark and tried to download the ccleaner.
I got this message:
Installer integrity check has failed. Common causes include incomplete download and damaged media. Contact the installer's author to obtain a new copy.

The filehippo download was OK. But I still get the message "Microsoft .NET Framework Version 2.0 is required to continue. The software is available for free download at http://www.microsoft.com/downloads/"
The printer was printing but it wouldn't perform other functions, like scanning.
Three months ago I had a laptop connected to this printer, and it worked just fine. The laptop ran on Vista. My currect computer is Windows 7.
Yes, I have uninstalled the Lexmark software, I have run CCleaner, and have tried the Windows 7 drivers. When I try to access the Lexmark Productivity Studio, I get this message:
Program name: app4r.exe
File origin: hard drive on this computer
When I select "yes," I go right back to "Microsoft .NET Framework Version 2.0 is required."
THAT WAS THE ANSWER !
I have successfully scanned and saved a document, and have every reason to expect that I can continue to do so.
Thank you for your help. How can I pay you more than the original $30? How do I leave feedback?
