Bitdefender installation problem

[curious]

Confusion over conflicting messages. Am installing Bitdefender

1) Superimposed over a window telling me it is successfully installed is a window saying “.Net Framework Initialization Error. Please set registry key HKLM\Software\Microsoft\.Net Framework\InstallRoot to point to the Network Framework Install location.”

2) I do not have that key.What I see in Registry under local machine...is Net Framework Setup, NDP,CDF, v4 but nowhere within these settings is ‘InstallRoot’ (Just remembered: years ago I think I deleted .Net Framework & then I had no luck when I tried what I think is called the repair tool…Did I doom myself?).

3) Hovering cursor on icon in systray, it say Bitdefender is active, but when I click an option, nothing happens.

4) Listed in Add/Remove programs is Microsoft .Net Framework 4 Client Profile with choice of Change/Remove. I dare not do either.

So, do I give up on Bitdefender and go with another AV?

Thank you so much.

(Win XP, SP3.
When I try to close the window advising of instllation error, either thru the X or Close, I get the Windows tone...)

For me, InstallRoot is in the right hand pane if I select HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework in the left hand pane:

If you want to persist with BitDefender, you could completely uninstall BitDefender and all traces of the .NET Framework. Then reinstall BitDefender. If it needs .NET Framework, it should automatically install that too.

Thank you, Hans!

Only default shows in my right-hand pane....

That means that .NET Framework is not fully installed (any more). So it's best to remove the remaining traces and then try again.

Tried, and tried again to install .Net Framework. No success. The last time I received message "Setup error." so, after x hours, I have given up and will tried another AV.

Much appreciate your time and suggestions.
