Lexmark 2500 Scanning

My lexmark 2500 scan won t work I get App4r exe problem

    First the all in one printed and scanned without problems. Suddenly, after some scanning that I interrupted, starting the Imaging studio became impossible, while the "app4r.exe" message was displayed.
    Cutting the power, and interrupting the USB-cable didn't help me.

    Now, printing works fine, scanning with the windows wizard is no problem, but the Studio still can't be started. I had the 2.0 version of the .net framework, but this doesn't seem to be the solution.

    My OS is XP home edition.

    Thanks for any help

    I think I may have installed it wrong, becuase NONE of the software that I need & is included is showing up.(i.e. Lexmark Imaging Studio) I'm ready to smash this cheeky little machine.

This is a solution for me, probably not for everybody.

I remarked that, in another user, which has no administrator rights, the "studio" still works, without the error message. So I can still scan.

In my usual user however the error persists...

I tried to install Microsoft .net framework version 2.0 onto my computer, so I can fix the problems with my Lexmark printer/scanner 2500 series, but everytime I try to install the framework program, it will not finish the installation.

Try scanning through another application like Word or the Windows Printers and Scanners wizard which you can get to through the "My Computer".

    Make sure you have Microsoft .net framework version 2.0 installed. This is required by the App4r.exe. If it got uninstall the Lexmark app will not work. You can get this for free from Microsoft at:

App4R.exe comes up on the screen when I am trying to scan in pictures. it then closes the imaging studio down and won't let me use it.

Please update your printer driver. Visit the Lexmark website at Select your operating system, download and execute the file. After updating your printer driver, try to scan again.
