Microsoft .NET 2.0 and older versions

[Guest]

I installed today the latest official release of Microsoft .NET 2.0 from
Microsoft Update website. Do I still need the previous .NET 1.0 & 1.1 older
versions installed or can they be uninstalled safely?
Another question, I noticed a new running process called "mscorsvw.exe"
under TaskManager after of installation of the new .NET 2.0. What is this
process for and/or its purpose?

Thnks in advance

Leave the older versions alone.

Hi Mark,

Two options to consider:

http://blogs.msdn.com/davidnotario/archive/2005/04/27/412838.aspx

and two is:

"I traced the behavior of mscorsvw.exe to find that it was looping while it
was enumerating the subkeys of the registry key:
HKLM\Software\Microsoft\.NETFramework\v2.0.50215\NGENService\Roots
Among its subkeys, "C:/Program Files\Common Files\Microsoft Shared/Help
8/Microsoft.VisualStudio.Designer.Interfaces.dll" was in inconsistent state.

Stop ".NET Runtime Optimiztion Service v2.0.50215_X86" and get into this key
with regedit.exe, and you may get an error "Cannot read the registry key".

The workaround for me was to change the service startup type to "Manual
start", reboot the machine, delete the inconsistent registry key (once the
service has been started once, that key is not accessible), and start the
service.
Then the service will not loop anymore. It will take some cpus for a while
to do queued jobs. And it will be okay.

You may have to re-register the above assembly again later with ngen.exe."
