My lexmark printer needs microsoft Net framework 2.0 version. I cant find it

Hi, in Windows 7 Microsoft.net framework 3 is installed and newer versions can be installed on it. If you try to install an older version, it will block your installation.
1-Try to download it from Microsoft\'s website and install it with administrator account privilege.
2-Go to the control panel, find out if Windows features are on or off. Try to check
Microsoft.net framework and then restart Windows. Then reinstall it.
3-If you have still problems, go to www.microsoft.com and search microsoft dot net framework 2 in windows 7.
kind regards

You can get the file to reinstall it here:
http://www.microsoft.com/en-us/download/details.aspx?id=19

You need to allow the Operating system to update from Microsoft. The .Net Framework is currently at version 4. You can download the updates yourself from the Microsoft website.

1. Before doing anything else, write down the .NET Framework versions which
are already installed:

whether service packs have been applied

2. Now see Resolution Method 2 in http://support.microsoft.com/kb/923100
(ignore the title). After running the appropriate/needed tool, (re)install
all .NET Framework versions manually using the download links on the page.

You can try to uninstall .net framework by using .net framework uninstaller and then try to install .net framework 3.0 or above
You can also use the following link:

This is an error having to do with the .NET framework. You probably have version 2.0.

I believe the problem is related to microsoft .NET Framework. I have researched and there are many posts of incompatibility between .NET Framework and many printers not just 1600. My 1600 stopped working and I traced the problem to upgrade to .NET Framework 3.5 I uninstalled 1600, then uninstalled .NET Framework 3.5 (and 3.0 as well for good measure), reinstalled 1600 and it is working fine now again. You can uninstall .NET versions using Add/Remove programs on the Control Panel. To avoid re-updating, I also turned off Windows automatic updates. I left .NET Framework 2.0. No problems with other programs but the computer did have trouble rebooting the very first time after I uninstalled .NET Framework 3.5 and 3.0. Unknown if that was related to the uninstall or a completely unrelated problem. Anyway if you want to try something less drastic than removing .NET versions, check out this Microsoft link:
http://support.microsoft.com/kb/961118
refers to a printer fix related to .NET. In my experience, the Microsoft fixes never work but you are welcome to try before uninstalling .NET Framework versions.

Windows Update error code "0x643" and Windows Installer error code "1603" are generic error codes. Typically, these error codes mean that the update was not installed. These errors codes are usually caused by a corruption in the .NET Framework installation or by an inconsistency on the MSI database state.

5. When you are prompted, restart the computer.

Note When you have reinstalled all the versions of the .NET Framework, you can use Windows Update to check for updates to the .NET Framework.

Newer Lexmark printers require the .Net framework be installed for the software to function correctly. Verify requirements by the documentation or during the software install. If need be download the correct version .NET 2 (I believe) from Microsoft's website.
