Microsoft Automatic Updates and .Net 3.5

Microsoft has started deploying the .Net 3.5 Framework (SP-1) in Windows Automatic Updates to any computer with any version of .Net installed. What does this mean to you, and if you want to upgrade your application from .Net 2.0 or .Net 3.0 to .Net 3.5, what do you need to do? This GoldMail will explain your options and how to go about upgrading.

    hi robin,

    we want to upgrade our target framework 2.0 to 3.5 sp1 and also wanted to create custom installer for making installation user friendly.

    We did all required evaluation and we are ready to go with result except one issue.

    Issue is the .net 3.5 sp1 prerequisite installation experience which is not showing proper progress during installation (e.g. 4% completed or something like that). It just stuck for sometime(about 25 minutes on .3Mbps speed) then show some progress. Yes, there is one text message mentions that it may take several minutes but it may not sufficient for users. Chances are very high to cancel installation by impatient user (users are always impatient due to one or the other reason, especially with medium speed internet which is very common for our users)

    I saw your above video and think on targeting client profile which shows good enough progress during installation but there are some features to be implemented which will require advanced WCF which is not included in client profile and we don’t to want to do two different move for .net framework.

    Any suggestion/work around ?

      Hi, I’m afraid I don’t have any good news for you. That problem with the .NET 3.5 SP-1 installation is well known, and I and others have given feedback to Microsoft about it to no avail. We just notified our customers and told them when it looks like it’s not doing anything, it actually IS, and to be patient.

        Thanks Robin,

        Amazing…. How Microsoft can avoid this type of issues?

        This is just restricting us to move forward.

          Maybe you could upgrade to the .NET 3.5 Client Profile, or even to .NET 4. The .NET 4 Framework (full version) is much smaller than the .NET 3.5 Framework.

            Thanks Robin.

            I already have checked both possiblities.

            Our product can’t work with .Net 3.5 Client Profile and .Net 4.0 will be must for Windows 7 users also so all of our users have to install .Net 4.0 and migration to windows 7 is happening very fast.

            So for us .Net 3.5 sp-1 is the best.

            Riken — I hear your pain. We first started looking at migrating to .NET 3.5 before Microsoft started pushing it out with Windows updates, and only about 10% of our customers had it installed. After Microsoft added it to Windows updates, when we checked again several months later, 90% of our customers had it installed. So this issue only impacted a small minority of our customers. We did get some calls, and we just talked them through the installation. There was very little kerfluffle around the upgrade. So don’t let this keep you from moving forward. You can always put a comment on the webpage where they install it from if you’re really worried about it.

    Hi robin,

    Our customers (who are using win-xp) are facing very serious issue installing .net 3.5 sp1 using exe on

    After running that exe, when it tries to download required files to install .net 3.5sp1, it can not. It shows ” re-establishing connection with the server (attemp x of 5).

    I googled for this issue and found that full packege of .net 3.5sp1 is the only option. I verified that problem is not due to virus or net connection issue.

    Can you please check on your side and let us known that it is not a problem of microsoft? Because full packeget is of size 232MB which is very big and can frustrate customers.

    Waiting for your reply.

    Thank you.
