.NET 4.0 SetupCache RRS feed

  • Question

  • Hi,

    I already asked that question in the WES 2009 forum but they pointed me here since my question concern the .NET 4.0 Framework (not client profile). Here's my situation : I've installed the .NET 4.0 Framework component in a WES 2009 image solution and everything works fine concerning the .NET 4.0 installation(for our OEM platform). However, since I have to lower my footprint, I investigated a little bit and found that the .NET 4.0 seems to keep its installer files under C:\Windows\Microsoft.NET\Framework\v4.0.30319\SetupCache\... which takes around 150MB on disk. Two files with a .mzz extension take almost all the disk space I mentionned above. Is it really necessary to keep those files since I'm on a tight disk restriction? Before that, I was using the .NET 3.5 SP1 Framework and there was no "SetupCache" directory keeping what seems to be some deployment files from the installer.

    I also have to mention that in my WES 2009 image, user has no access to uninstall/remove/repair any installer already deployed in the OS.

    I hope someone can clarify this to me since I'm going through that transition and want to be as lean as possible and functional in a scenario where I'm in an embedded environment.

     

    Regards

  • Hello Ben,

    I take a look at the SetupCache folder on my side, and just as you mentioned above I found two .mzz files take the most part of disk space:

    C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\SetupCache\Client\netfx_core.mzz

    C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\SetupCache\Extended\netfx_extended.mzz

    And as far as I know actually the .mzz files are simply the decompressed installer files. And if the installation is done and working, you should be safe to delete them.

    Please take a look at the following like for more information:
