"Object reference not set to an instance of an object" RRS feed

  • Question

  • Hello,

    The problem appears in Visual Studio, that when I try to create a new Project, it always drops the message "Object reference not set to an instance of an object". I have uninstalled and installed Visual Studio, multiple times, but the problem appears always. Also, I 've tried to delete my Configurations from Tools/Import and Export Settings/Reset all Settings/...

    and the same from the main folders-files of Visual Studio, but when I open VS, out of nowhere, all old configuration appear back, with the problem.

    I am desperate, spend more than 4 full days for that.

    I beg for your help, Please!

  • Hi dibellos,

    Thanks for your feedback.

    The problem you faced may be that the residual files you installed in the system disk

    Please have a try with these solutions below:

    1. First, you should know the version of your VS: delete %Local App Data%\Microsoft\Visual\Visual Studio\the Version of Vs\Component Mode. Alternatively, use the Clear MEF Component Cache extension
    2. Before this, you should back up your registry . If you still face the message, "Object reference not set to an instance of an object". Then: Open window-->run--->input the order "Regedit"-->open the registry—>Open the path "HKEY_LOCAL_MACHINE\SYSTEM\Current Control Set\Control\Lsa\FipsAlgorithmPolicy"-->set the "enable" to 0
    3. Reinstall the VS: Use the force command to uninstall the VS first.

    VS2017: Use the Window command prompt.

    CMD:  input the message: /Program Files (*86)\Microsoft Visual Studio\Installer\resources\app\layout\installcleanup.exe -f


    CMD: input D:\vs_ultimate.exe/uninstall/force

                Where D: is the location of your installation media

    Then reinstall the VS.

    Hope it could help you.

    Best regards,
