Installing .net 1.1 after installing 2.0

[Guest]

Hi all,

I have .net 2.0 , visual studio 2005, sql server 2005 etc installed in my
system. Now I also need .net 1.1. Can I use .net 1.1 CD (or just the 1.1
redistributable??) and install this side by side to 2.0? If so what are the
precautions I should take ? will anything break after doing so? I am using
windows XP operating system.

Thanks

Hi,

Thanks for posting!

For the current issue, I don't recommend you to install the early version
for .NET framework into the current machine which has been installed the
latest version for .NET framework. Because this will cause that the
environment variable of system and registration information of IIS are
modified. If you have to follow this way, I suggest you use the
aspnet_regiis command to register the ASP.NET to IIS for both v1.1 and
v2.0. After this, please modify the environment variable as the normal
system which is installed the .NET framework v1.1 first and v2.0 second.
So, the application maybe run correctly.

Thanks for your understanding!
