Installation Path from Registry

[noobxl]

Hello,

I'm trying to let Setup Factory 8.0 automaticly select the good installation path by reading Registry.Local Machine/Software/test. In that folder is a registry key named "programpath" and the value contains the good installation path.

I tried to edit the Welcome to installation screen @ On Next... But it fails.

So any help or answers would be pleased.

Usually helps if you post the code you TRIED, most won't just write you code because you asked...
But I'm in a good mood.. ;-)


local ProgPath = Registry.GetValue(HKEY_LOCAL_MACHINE, "Software\\test", "programpath");
And then if you need it in a session variable:

SessionVar.Set("%ProgPath%", ProgPath);
or combined into a hard to read:
SessionVar.Set("%ProgPath%", Registry.GetValue(HKEY_LOCAL_MACHINE, "Software/test", "programpath"));[/

Hmm... I get an empty path then.

I have this in On Next code of Welcome To Setup.

SessionVar.Set("%ProgPath%", Registry.GetValue(HKEY_LOCAL_MACHINE, "SOFTWARE/test", "testpath"));

Screen.Next();

And in the Select installation path I got:

Default folder: %ProgPath%



Store result in session: %ProgPath%

Maybe I have to put %ProgPath% first in the session variables. But how exactly?

Try \\ instead of /

Does this value exist?
are you checking Application.GetLastError()?

[noobxl]

Yes that did the job.

Thank you very much for your good help.
