无法在Visual Studio 2017中安装Xamarin

Question

I just installed Visual Studio 2017 in my Windows 10 ENTERPRISE with an offline installer, but I have a problem with one workload: Xamarin When I launch the visual studio installer and it arrives to the xamarin installation, I get this error:

Package 'Microsoft.VisualStudio.Xamarin.Preparation,version=15.0.26621.2' failed to install.

I found your error here, a guy found a workaround you might want try that: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/dc0358cc-7554-4af3-9664-f892392d157e/package-microsoftvisualstudioxamarinpreparationversion150262280-failed-to-install?forum=vssetup

The workaround:

I got the same issue, here is workaround Create the folder C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\Common7\\IDE\\Extensions\\Xamarin Copy any files to C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\Common7\\IDE\\Extensions\\Xamarin Run the setup again. The root cause is that there is a command trying to delete some files under xamarin folder and it failed if there is no file in there.

If that doesn't work perhaps try this:

Hi jenkstom, If the above didn't help, how about trying with directly download and install the Xamarin packages from: https://www.xamarin.com/download-it?_bt=101035044668&_bk=xamarin&_bm=e&gclid=Cj0KEQjwioHIBRCes6nP56Ti1IsBEiQAxxb5G2bCyosDgH-pB7hqJLAWdxB1dVFoZj_bufKCnO6AkKYaAtt88P8HAQ Please temporarily disable the AV software and firewall during the installation. As far as I know, you computer configuration meets the Xamarin install system requirements. Best Regards,
