I want to install ASP.Net MVC 3 but it gives me error (0x80070643) and rollback installation.
I had Visual studio 2017 which i uninstalled and now I have only VS 2012.
I have attached screen shot as well.
I tried to install ASP.Net mvc3 with VS2012 repair but it failed there as well.
I tried trailing backslash in regedit keys as well but no success.
Any expert opinion.
IF ABOVE LINKS DOES NOT WORK FOR YOU THEN TRY BELOW; this will always work for you.
I resolved it after doing the following steps;
1. copy following directory from your colleague/friend computer to same path on your machine who have properly installed ASP.Net MVC3. C:\Program Files (x86)\Microsoft ASP.NET (make sure they have ASP.Net MVC 3 folder inside with assemblies) 2. reference following dlls from these folder into your mvc project; System.Web.Mvc from C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies System.Web.WebPages from C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies System.Web.WebPages.Razor from C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies System.Web.Helpers from C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies 3. apply assemblybinding in web.config <runtime> <assemblyBinding> <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/> <bindingRedirect oldVersion="0.0.0.0-126.96.36.199" newVersion="your mvc dll version you need 188.8.131.52 or 184.108.40.206"/> </dependentAssembly> </assemblyBinding> </runtime>
