How can I check whether .NET Framwork 2.0 is installed or not?

In control pannel open "add/Remove programs"  the list is in alphabetic order.  Look for Microsoft .Net Framwork

or I could finnish reading the entire question before I hit post...sorry didnt notice the "a Win32 Delphi app?" part.  

The NET runtime installs a registry key, you can check it.

For example,
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramewor k\policy\v1.1

for version 1.1.

I have got to check my spelling!

uses

Thanks, it worked but why you're checking "policy" folder not just:

\SOFTWARE\Microsoft\.NETFramework\vXXX

?

Because there is no key there, that I can find, with that designator, I.E.,

\SOFTWARE\Microsoft\.NETFramework\v1.1 does not exist.

Those keys are listed under policy,

SOFTWARE\Microsoft\.NETFramework\policy\v1.1 and does exist.

Are you sure you don't have the key? I have it:

\SOFTWARE\Microsoft\.NETFramework\v1.1.4322

Please check it again.

I do not on my PC here. But I do have

\SOFTWARE\Microsoft\.NETFramework\2.0.40607
and
\SOFTWARE\Microsoft\.NETFramework\2.0.40903
and
\SOFTWARE\Microsoft\.NETFramework\2.0.50727

You should still have the core version listed under policy and I believe that is what you were seeking.
