Do I have seizures with net framwork?

In my programs, I see:

  • NET. 1.1 framework
  • NET framework Service Pack 2 2.2
  • NET framework 3.0 Service Pack 2
  • NET framework 3.5 SP1

Are there conflicts here that I have to solve?  Suddenly I can not scan from my printer and was informed by the company of printer the problem may be that my net framework is 3.0.

Short answer: no, all of these versions of the .NET Framework are compatible and may even be necessary.

Long answer: (from http://blogs.msdn.com/b/astebner/archive/2009/04/20/9557946.aspx)


When you install the .NET Framework 3.5 SP1, it will also install the .NET Framework 2.0 SP2 and the .NET Framework 3.0 SP2 behind the scenes.  You cannot use the .NET Framework 3.5 SP1 unless you also have the .NET Framework 2.0 SP2 and 3.0 SP2 installed.  Therefore, you cannot uninstall the .NET Framework 2.0 SP2 and 3.0 SP2 if you have the .NET Framework 3.5 SP1 installed.  If you try to uninstall these versions of the .NET Framework, their uninstall process will block and tell you that they are needed by another application on your system.

The .NET Framework 1.0 and 1.1 of the .NET Framework can be installed side-by-side with the .NET Framework 2.0, 3.0, and 3.5.  Most of the applications that have been created for the .NET Framework 1.0 or 1.1 will automatically use the .NET Framework 2.0 instead if it is installed on the system.  In most cases, this means that you do not need to keep the .NET Framework 1.0 or 1.1 is installed on your system if you have already installed .NET Framework 2.0.

However, there are some applications that are configured to require a specific version of the .NET Framework, even if later versions of the .NET Framework installed.

  • I have a craft net router is compatible with the printer Hp 5725

    Today, I bought a Hp 5725 printer all-in-one. I have the software windows 7 on my desktop & family has 2nd & 3rd generation Apple iPad. We have a router net gear. They are all compatible? Thank you for your help.

    Hello

    What is the model of your Netgear router. 99.9% of the routers wireless (any brand) will be compatible with the normal WiFi configuration. I don't think that your router is on the. list of 1%.

    Kind regards.

  • NET Framework 3.5 can be reinstalled with NET Framework 4 already present?

    I am running Windows XP, SP3, with NET Framework 4.  I have some old software I need to re - install that requires Framework 3.5, which can be downloaded from Ms.  But, is it normal to have installed 3.5 and 4 at the same time?  I don't want to remove 4 just for this temporary application, unless absolutely necessary.  It would be temporary, because the task with the old software can be done quickly and then everything restored.

    The quick answer is YES.

    And the answer more detailed, just in case you want to...

    .NET framework can currently be divided into 4 families:

    (a) 1.0

    (b) 1.1

    (c) 2.0 / 3.0 / 3.5

    (d) 4.0 / 4.5

    (4.5 is not available for XP, but since XP is dying, it won't hurt to learn about it now).

    These families are independent of each other and can co-exist.

    Higher versions of each family can run programs written for versions inferior to the same family.

    For example, you can use 3.5 to run programs requiring 2.0.

    Compatibility between families, while it is not impossible, is usually offered nor guaranteed.

    Just for further confusion.

    3.5 "adds" 3.0, and 3.0 "adds to the ' 2.0.

    4.5, on the other hand, "replaces (overwrites) ' 4.0.

  • Anyone who has a problem with net.exe?

    Windows 7 Ultimate x 64 with all patches

    Open a command window and tried to run net.exe:
    C:\>NET
    This version of C:\Windows\system32\net.exe is not compatible with the version o
    f Windows that you use. Check your computer's system information to see information indicating if
    r you need a x 86 (32 bit) or x 64 (64-bit) version of the program, then told the
    CT the software publisher.

    Checked net.exe and found that it was not true.  Did a scan using Microsoft Security Essentials and it says that it ASNA 2 files and found no threat.

    The original net.exe was renamed appearently net1.exe.

    The owner of the file is trustedinstaller.  I can't move, rename or delete it even when running as administrator.  The system says that I need the permission of the Trusted Installer.

    Any idea of what could have caused this and how get rid of?

    Hello, saberman

    The fact that the Details tab of the property sheet for your net.exe is not filled with the correct information is undoubtedly a problem. This is why suggested Yann Support engineer runs the System File Checker ("SFC"), which is designed to find and replace corrupt or missing system files from backups in your store of components (windows side by side or WinSXS folder; note that the KB929833 article I just linked ("System File Checker") has yet to be re-written to reflect the fact that) Since the advent of Windows Resource Protection in Windows Vista is no longer a dllcache folder in System32 and file system backups are now located @ C:\Windows\winsxs\Backup).  Running SFC should have found the problem with net.exe & repaired, without needing to resort to a system restore, which can sometimes cause problems as indicated by the error message you posted, i.e. that net.exe "is invalid for your system.  I suggest to read the article from KB929333 on SFC and see if enforcement of that tool is not correct the problem. If not, a good starting point for troubleshooting to solve the problem is the sfcdetail.txt newspaper, which shows the results of each operation of checking files and each transaction attempted repair. instructions for how extract/transform/load this journal of his 'home' in the service area global log (log CBS.log) in a usable format appear under the heading "How to view the details of the System File Checker process" of KB929333, and the instructions on how to repair files that are not SFC are included in the article "How replace manually a file system damaged by a known file correct copy" section (the two sections are available by clicking on the circle '+' sign next to "for more information").  It is to note that it is not uncommon to have to run SFC repeatedly to deal with corruption - 3 times is the recommended minimum, and I personally saw him require more... the error dialog box that you see leads me to believe there is more harm than simply a lack of functionality net.exe and CFS can be just the thing to get things straightened.

    That said, it is also true that there is often more than one place that a protected system file is stored, other than the C:\Windows\winsxs\Backup on a Windows 7 computer. Typical areas of other instances of the net.exe include C:\Windows\winsxs\x86_microsoft-windows-net-command-line-tool_31bf3856ad364e35_6.1.7600.16385_none_5208a7a3d3caa54c records, while net1.exe can usually be discovered (on a 64 - bit with an AMD processor machine) and two C:\Windows\winsxs\x86_microsoft-windows-net1-command-line-tool_31bf3856ad364e35_6.1.7600.16385_none_86b24994b5e6bfbf at C:\Windows\winsxs\amd64_microsoft-windows-net1-command-line-tool_31bf3856ad364e35_6.1.7600.16385_none_e2d0e5186e4430f5 (note that the part "31bf3856ad364e35" of these folder names may vary). There may be other places in the store of components according to these things the way that system restore several times has been executed, whether an OEM computer (i.e., a pre-loaded with Windows by an Original Equipment Manufacturer) who has already found "Factory Spec", which updates Windows, service packs and other fixes/patches have been applied, and other factors.  The trick is to know what file is correct to use to replace a version corrupted in C:\Windows\System32 - which is not always easy to determine - and by "taking possession" file corrupted in question, so it may be deleted or replaced.

    The windows component store peut usually be used as the source of a file replacement for one that SFC cannot fix by using the information in C:\Windows\winsxs\Backup, but a user must make sure that they know what they are doing to avoid the disaster (this is why Microsoft has included the "automatic" option to perform a "repair installation" to correct the corruption of the system)- and if the user has access to another , work computer running the same version of Windows, or for the installation media (if no Service Pack or other update of the kernel has been applied), or "slipstream" self-created media (if Windows 7 Service Pack 1 has been applied) designed specifically for the operating system in use, extraction verified copies of the record of those required are usually an "easier" approach  Detailed instructions on the use of all these forms of installation with SFC media are in the Wiki author try * 3of 6 December 2013 post to the thread of community "System File Checker and access files blocked, while detailed instructions on how to create a"slipstreamed"media are in his post from August 25, 2012 to pg 3 of the thread"guide to recovery of Windows 7 Home Premium account user word of. past lost, unable to connect, connection problem"(it is also useful to have a look at this whole thread, which has very useful information about different Windows 7 recovery options, and that includes links to downloadable PDFs (portable document files) on each of the options many.).  BTW, these pdf files is hosted on the cloud OneDrive service, which is where we usually place downloaded files (for example the zipped copy of your corrupt net.exe file you mention) and make them accessible to third parties. to learn more on how to do that I recommend community animator Gerry C J Cornellexcellent tutorial 'Forums Community Microsoft"on its site Computer Tips of Gerry .

    As you noted, net.exe (and net1.exe - which, as I have, reminder has been around in all NTFS OS since @ least NT4.0 however hardly documented; official documentation only I ever)

    seen mention that this is the Windows Embedded article Utility Net.exe : thus, as well as many others

    protected system files) is 'held', in terms of security of the file/folder permissions, by service "Trusted Installer".  The implementation of the Protection of resources of Windows, Vista, limit property of this service-protected system files in large part to protect themselves against malicious or accidental deletions.  However, a user with administrative privileges ('high') can always take ownership over any file and then manipulate it at will.  TechNet Library 'ownership of a file or a folder' article provides advice on how to do it, but without expertise in the creation of a file batch, macro, visual basic program, Power Shell command or similar to handle this action based on a large scale, the procedure described is essentially limited to a one-at-a-time approach.  In my opinion, a better technique is to add the ability to take ownership of a file or folder from the context menu (right click "") of the operating system. many people have found the information and automated "registry hacks" in the Seven Forums tutorial "Windows 7: take ownership shortcut" very useful in this regard.  Even with this capability, users can occasionally run through a file that stubbornly refuses to behave even when the property has been reassigned to the said user. in this case, the stand-alone freeware program ("Portable Executable", requiring no installation runs) UnLocker can be valuable.

    I'm hopeful that SFC be enough to take care of this problem for you, but if not, I would also consider

    check the integrity of the hard disk / partition with Check Disk.  If none of these solves the problem, a repair installation may be in order.  Useful information on this procedure can be found in article KB2255099, "How to perform an upgrade in Place on Windows Vista, Windows 7, Windows Server 2008 and Windows Server 2008 R2" and the tutorial of the Forum seven "How to do a repair of trouble Windows 7 installation.  Good luck!
