I am trying to re-install VS2008 SP1. Why? I installed the VS2008 Forward Compatibility

I am trying to re-install VS2008 SP1. Why?

I installed the VS2008 Forward Compatibility Update (KB974558), in order to be able to access TFS 2010 from VS2008. Everything went fine; there were no error messages. When I start VS2008 and click Help..About, I can see that KB794558 is installed.

But even though the FCU is installed, I still cannot add a TFS 2010 server path into Visual Studio 2008, without getting the error TF30335. The server in question is a codeplex server; I understand that codeplex upgraded to TFS 2010 in July.

Some websites have suggested re-installing VS2008 SP1 in order to correct this TF30335 error. But when I try doing that, the install asks for the original installation media for VS 2008 Team Suite (vs_setup.msi), which I no longer have.

Other websites, like this one, suggest manually tweaking the registry to add a TFS 2010 URL. When I restart VS2008 after doing this, I get the TF253022 error, which says, You must update your client with the Forward Compatibility Update. As I said, I’ve already installed that.

  1. Is there a way to (re-)install VS2008 sp1 without access to the original VS2008 installation media?

  2. Failing that, is there a way to avoid the TF30335 error, after installing the FCU (KB974558)?

  3. Is there a way to make the Forward Compatibility Update, uhm…. really work?

    Answering my own question…

    I was able to re-install VS2008 sp1, by providing an image of the VS2008 90-day trial product. The installation of SP1 requested vs_setup.msi, and the 90-day trial ISO satisfied that requirement.

    Once I did that, I was able to re-install the Forward Compatibility Update for TFS2010; at that point, I was able to connect to a TFS 2010 instance (Codeplex.com) from VS2008.

    Also, to re-iterate, the installation order I used to get the Forward Compatibility Update to install, was the same as has been suggested elsewhere on this question, and also elsewhere on the internet:

    1. VS2008
    2. Team Explorer 2008
    3. VS2008 SP1
    4. Forward Compatibility Update.

    In my case, VS2008 was already at SP1 level, and already had Team Explorer installed. No matter. I re-installed Team Explorer, then SP1, then FCU. I did not re-install the original VS2008 (because I don’t have the original media!)

    One note – the first time I tried this, it didn’t work. I installed each of #2, 3, and 4 twice, before VS2008 was able to connect correctly to TFS2010.

    I hope this helps someone else.
