.NET Core errors on installation (WebToolsExtensionsVS14, encountered error: 0x80070643) RRS feed

  • Question

  • I have a solution that contains an .xproj project file and the project fails to load with an (Incompatible) tag.

    I've tried many times to install DotNetCore.1.0.1-VS2015Tools.Preview2.0.3 and I get a dialog stating that 'The specified account already exists.'

    The log states the following 4 times, gives up, and rolls back.

    [213C:26A4][2017-02-02T12:36:59]i301: Applying execute package: WebToolsExtensionsVS14, action: Install, path: C:\ProgramData\Package Cache\{BFC344B0-DCDE-36EB-AB05-CB194F2BE946}v14.1.21111.0\packages\WebToolsExtensionsVS14_69.msi, arguments: ' ARPSYSTEMCOMPONENT="1" MSIFASTINSTALL="7" SKIP_SETUP="1"'

    I've tried both the "DotNetCore.1.0.1-VS2015Tools.Preview2.0.3.exe" and from the layout with the same results. I've checked and meet the posted pre-requisites. I've tried uninstalling VS and reinstalling and nothing seems to help.

    I can not find any signs of an account that it thinks is already in existence.

    This issue is a blocker!

    Thanks in advance.

  • Hi Eric,

    Thank you for posting in MSDN forum.

    Recently, I met some community members encountered the .Net Core installation problem, someone solved it by fixit tool, would you mind having a try with it:

    1.Download the Windows Fixit tool from:

    https://support.microsoft.com/en-sg/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed

    2. then run it to repair issues including corrupted registry keys or others. 

    3. Restart your machine and run the /layout .Net Core install .exe to run and install it again.

    At the same time, please temporary disable your AV software and firewall.

    Any problem persists please feel free to tell me.

    Best Regards,

  • Hi Lana,

    Thanks for your feedback!

    I tried following the steps you outlined but got hung up on getting IT to temporally shut down AV software.

    Since the software title for 'Web Tools Extensions' never showed up in the Fixit tool, I was never able to select it as the item I was having problems with. Selecting title 'Microsoft .NET Core 1.0.1 -...' items through Fixit and uninstalling each one and then reinstalling also didn't fix the xproj (incompatible) issue.

    I even uninstalled 'Microsoft ASP.NET and Web Tools 2013.5 - Visual Studio 2013' and tried another install of 'WebToolsExtensionsVS14_69.msi' which kept giving the message 'The specified account already exists.' and failing the install.

    What finally did work was to uninstall 'DotNetCore.1.0.1-VS2015Tools.Preview2.0.3' and then go into the registry and rip out references to "Microsoft ASP.NET and Web Tools" of which I found lingering 2013 references as well. After doing this, I was then able to successfully install 'WebToolsExtensionsVS14_69.msi', run a repair on VS 2015, and finally run the 'DotNetCore.1.0.1-VS2015Tools.Preview2.0.3' without errors.

    I am now able to load my solution containing a .xproj file with out (Load Failed) or (Incompatible) errors.

    One other note:
    I also found that 'DotNetCore.1.0.1-VS2015Tools.Preview2.0.3.exe' install would produce the 'The specified account already exists.' dialog error. But the 'DotNetCore.1.0.1-SDK.1.0.0.Preview2-003131-x64.exe' from the layout packages would appear to be a successful install, looking at the log and the results proved that the 'WebToolsExtensionsVS14_69.msi' failed to install and never displayed the dialog giving the appearance everything was good.

    Again, Thanks for your feed back and I hope this might help someone in the future.
