Hi, I am trying to install/repair the DotNetCore.1.0.0-VS2015Tools.Preview2.0.1.exe and I get an modal on Microsoft .NET Version Manager 1.0.0-rc1 saying "The specified account already exists", ending the installation with an 0x80070643 error. Please find the logs attached.

+1, i found that folder DotNet.Web is missing and repairing/installing/uninstalling VS or tools never creates it.

@mkoutroupis Can you add the individual log for the MSI (dd_DotNetCoreTools__20160831235612_004_DotNetVersionManager_x64.log)

The account error you're seeing is related to a security change in the installer service in the OS - there's been a few updates to address issues that were introduced when the service was originally update. You can take a look at https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed and try to use that to remove the product that's failing.

[mkoutroupis]

@joeloff Please find the log attached.

[joeloff]

Could you try the following:

1. Open Programs / Features (aka ARP)
2. Look for Microsoft .NET Version Manager (x64) 1.0.0-rc1
3. Uninstall it
4. Repair .NET Core Tools

[mkoutroupis]

Well the problem is that is listed in the Programs / Features!

[softlion]

joeloff: done (mkoutroupis: search 'version' only).
Folder DotNet.Web still missing

[mkoutroupis]

@joeloff @softlion Still not there...

[lednhatkhanh]

+1 Facing it right now, I uninstall VS first and then tried to uninstall this, got this message...

[lednhatkhanh]

@joeloff I remove it, still can't remove the toolling.

same issue here & cannot uninstall it either. version manager not listed in program features & MS tool from here, https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed cannot repair reporting "no issue" present.

Fixed by reinstalling Windows 10 from scratch.

I fixed this by uninstalling my current version of VC 2015 x64 redist. Then I installed v14.0.23506 of the redist and DotNetCore.1.0.1-SDK.1.0.0.Preview2-003131-x64.exe. Then I managed to uninstall this and the installed packages.

For some reason DotNetCore.1.0.1-SDK.1.0.0.Preview2-003131-x64.exe tries to install that specific version of vcredist and fails due to signature problems.

I'm having a similar issue with "Microsoft .NET Core 1.0.1 - VS 2015 Tooling Preview 2". I've been trying to uninstall VS 2015 and all the obsolete tools that its installer left behind. I can't "Uninstall" due to the same "The specified account already exists" error: https://gist.github.com/fragmer/3d52bd81bf07c7b23e91e3c765f5816b

• Uninstalling "Microsoft .NET Version Manager" did not make a difference.
• Installing/uninstalling VC 2015 x64 did not make a difference.
• Microsoft's install troubleshooter fails when used on this package.
• Re-downloading the original installer and running "Repair" also failed: https://gist.github.com/fragmer/7977ca87345a451cf0a8be9255961b15

The logs mention "WebToolsExtensionsVS14.msi" right before failing. I've uninstalled something with "Web Tools" already though, and that succeeded.

Any more workaround ideas would be greatly appreciated.

Exactly the same as @Fragmer

Same issue as @Fragmer & @JosepAlacid

[StephanZahariev]

I was able to uninstall it by:

1. Installing again Visual Studio 2015 with SP1
2. Uninstalling .NET Core tooling preview
3. Uninstalling VS 2015

[joeloff]

@Fragmer can you attach the log from 3/8 for the uninstall for WebToolsExtensions that failed. It should be in your %temp% folder.

[mstefarov]

@joeloff I'm afraid those files no longer exist. Reinstalling Windows ended up being simpler than uninstalling all VS 2015 components.
