.NET Forum / ASP.NET / General / July 2007Can I uninstall .NET 1.0 and 1.1 from Windows 2003 Server?
Hello, Sorry if this is slightly OT, but I reckon there would be folks here who would know... I have a Windows 2003 Server box, SP4 and .NET 2.0 installed. Trouble is that it also has .NET versions 1.0 and 1.1 installed. I would just ignore them, but occasionally one or two of the web sites on the machine seem to set themselves to the wrong version, and this causes errors. I have no idea why or how this happens, but it does happen from time to time. I would like to remove 1.0 and 1.1 completely as all my sites use 2.0. What's the best way to go about this? TIA  SignatureAlan Silver (anything added below this line is nothing to do with me) > I have a Windows 2003 Server box, SP4 AFAIK, the latest SP for Windows 2003 Server is SP2: http://technet.microsoft.com/en-gb/windowsserver/bb463273.aspx Do you mean Windows 2000...? > I would like to remove 1.0 and 1.1 completely as all my sites use 2.0. > What's the best way to go about this? I must admit I've never tried, as there is absolutely nothing whatever to be gained by doing this, other than a bit of hard disk space...

No, I meant Windows 2003. I just installed SQL Server on a machine, and put SP4 for that in. I got the wrong number when typing the SP for Windows ;-) So yes, it's Windows 2003 with SP2. >> I would like to remove 1.0 and 1.1 completely as all my sites use >>2.0.

Well, as I explained, I *do* have something to gain, namely a lack of errors caused by the mysterious version changing gremlin in my machine! So, do you know a way of doing it? Only 2.0 shows up in the list of things to uninstall, presumably as 1.0 and 1.1 came with the OS.

No, it's not urgent. I'm building up a new machine to replace a current server. It's going to take some time to finish anyway, so I can hang on. Thanks SignatureAlan Silver (anything added below this line is nothing to do with me) You don't need to physically uninstall them, only unregister them. drive:\WINDOWS\Microsoft.NET\Framework\v1.0.3705 is only a stub directory. Its funcionality is disabled in W2K3 and, who knows, maybe you'll find a use for .Net 1.1 down the line, so you shouldn't uninstall .Net 1.1 physically. What you can do is run, from a command window in this directory : drive:\WINDOWS\Microsoft.NET\Framework\v1.1.4322 aspnet_regiis -u That will unregister .Net 1.1 in IIS, leaving you with only the .Net Framework 2.0 registered in IIS. That will, effectively, do what you want to do. If you feel the need to confirm this, run aspnet_regiis -lv *before* you run the aspnet_regiis -u command and *after* you run the aspnet_regiis -u command. You'll find that, the first time, you have .Net 1.1 registered, but the second time it won't be registered. Also, after you run that command, you will only be able to see the 2.0.50727 version in the ASP.NET tab in the IIS properties for all your applications, and all your applications will default to ASP.NET 2.0. If that's what you want...go ahead and do that. Juan T.

OK, if I can disable it without uninstalling it, I don't mind. My main interest is in it not being available to my friendly version-changing gremlin! <snip> >If that's what you want...go ahead and do that. Can't say I'm desperate to do it, but I can't see any other way around the problem. I have never found any reports of this bug, and it's so elusive that it's impossible to track down. Unfortunately, its effects are fairly serious. Thanks for the help >Juan T.
