I did a new installation of High Sierra, Parallels and Win 10. I need net framework 3.5 from Microsoft for two elder Softwares but it doesn't work. The Win Support did a new in place installation of Win 10 without success. They told me the reason must be in Parallels and I should do a new installation of the virtual machine!? Does anyone has experience with this?
Hello Henning, 1. Enable .Net 3.5 in "Windows Features Turn On or Off". You can find it in Start Menu search. 2. Mount Windows 10 ISO to the VM 3. In Command Prompt (admin), execute this command DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:x:\sources\sxs 4. Now install the application which need .Net Framework and check. e.g: If you have Windows setup at "D:" drive, replace "x:" with "d:" If you have Windows setup at "D:\Installers" folder path, replace "x:" with "d:\installers" And also, make sure that "sources\sxs" folder exists in your Windows 10 installation media. When run from the command prompt, it will start installing the .NET framework. Please keep patience as it might take some time to install the .NET Framework. Once done, restart your system for the changes to take effect. Details on command line parameters, for your reference and knowledge: /Online targets the operating system you're running (instead of an offline Windows image). /Enable-Feature /FeatureName:NetFx3 specifies that you want to enable the .NET Framework 3.5. /All enables all parent features of the .NET Framework 3.5. /LimitAccess prevents DISM from contacting Windows Update. /Source specifies the location of the files needed to restore the feature (in this example, the x:\sources\sxs directory).
Try using this command and check. DISM /Image:C:\test\offline /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:x:\sources\sxs You can also refer to Microsoft Doc for complete instructions.
