[RESOLVED] [Inno Setup] Check if Net Framework 2.0 is installed

Hi!!

How can i check if Net Framework 2.0 is intalled

Thks

Doesn't the .NET framework check to see if it is already installed when it attempts to install?

I dont know couse i have already the net framework installed on all my computers.
But does the Inno Setup does that by default?

Inno has nothing to do with the .NET framework, so it doesn't check for it.

So, why don't you attempt to re-install the .NET framework to see if it checks if it is already installed???

Something else to do is to do what I have started doing lately.

1. download and install Microsoft Virtual PC 2007 (FREE)
2. install an OS on it (requires you have a liscense for that OS that not already being used)
3. install all Windows updates
4. defrag and compact the install
5. mark the virtual hard drive as readonly
6. create a differencing hard drive based main one you just created
7. install and test what ever you want, only the differencing disk will change
8. repeat steps 6 and 7 as needed

I know this doesn't answer your immediate issue, but may be useful, and it's a good way to test your installations and applications in various systems as if you were installing it on a users PC.

I've provided a link to the artiale that describes using Virtual PC and differencing disks.

Thks a lot Cavar, but i dont have 2 licenses, i just have my windows.

How can i do a If in Inno Setup like:

If Registrykeythattellsmeifnetisinstalled=true then
continue installer
else
Msgbox("Pls visit http://... to install net framework"
end if

The key i go find to see which is it.

You can write code for that in Inno Setup.

that i already knew! Thks anyway!!!

But how can i do the part continue? And how can i do for this code to be processed before anything?

EDIT: I found how to do part of it

VB Code:

[Code]
function InitializeSetup(): Boolean;
begin
If {reg:HKLM\Software\Microsoft\NET Framework Setup\NDP\v2.0.50727,Install} := 0 then 'in here i dont know how to do this correctly
MsgBox('The setup detected that .Net Framework 2.0 is not installed in your system.' #13#13 'Please install it. You can download it from http://www.microsoft.com/downloads/details.aspx?FamilyID=0856eacb-4362-4b0d-8edd-aab15c5e04f5&DisplayLang=en', mbInformation, mb_Ok);
Result := False
end;

now i just need to know how to make a clickable link the msgbox and how to the the if line, if u know what i mean.

You can ask Klienma. He does Inno Code. He hangs out in the VB .NET forums.

Hi,
just dropped by since I was searching for a way to check if windows media player is installed on a win2k system within inno ...
if anyone knows please let me know...

Anyway here is some code to check for .net 2.0... and send the user to ms to download .net if not available on the system...
:wave:
