How to install .net from CD rather than internet
I am working on an installer and now we have a requirement to have .net 2.0 as a prerequisite.

However, the program is designed for non-networkable machines. As such, I'd like to include the binary on the software cd and have the installer detect if it is needed.

It will determine if it is needed or not. Then will say it is strongly recommended, install y/n.

then install from cd, after, continue nsis installation.

is this possible? better ideas?

thanks and regards

Sure.

To check if v2 is installed or not:

System::Call `mscoree::GetCORVersion(w .R0, i ${NSIS_MAX_STRLEN}, *i) ?u`
StrCpy $R0 $R0 1 1

ExecWait `"$EXEDIR\DOTNET\dotnetfx.exe" /q:a /c:"install.exe /noaspupgrade /q"` $R0

Can you please specify what the rest of the parameters and flags are doing in the execwait...

Mainly /q: a /c: "install.exe" ...

so i can put this in the oninit function, show dialogue, if yes install .net, if no, just proceed with rest of install?

1. Look it up on Google.
2. Use MessageBox.

Is it possible not to use extracting to C drive? Perhaps use an msi file directly instead?

You don't need to extract anything. Just run the dotnetfx.exe directly from the CD. That path you specify in your ExecWait instruction defines that. If you have your main setup on the root of the CD then $EXEDIR will give that root (i.e. D:\).
