How can I update the update file ?
Dear all.

I made an update file update.exe that connect 2 the net,
downloads some files and replace 'em with existing files,

But how can I also update the Update.exe that do all that stuff ?
(must I use another app to replace this file ?)

Any ideas ?

Spawn another nsis installer as you suggested, or I guess you could use something like :-

File new_update.exe
Delete /REBOOTOK update.exe
Rename /REBOOTOK new_update.exe update.exe

Got another idea...
I got another one,

at the end of the update (after I have update.tmp)
I can execute MyApp.exe /Update
and this will only replace update.exe with update.tmp

But how can I close the already running update.exe ?
(how can I find it with FindWindow() ?)

Why close it using FindWindow()? Why not instead just use Exec to run MyApp.exe and then quit the installer. MyApp can then replace the update.exe. If MyApp tries the replace too quickly you can wait for a bit or try replacing 10 times in a row until it succeeds, or something similar.

but what if the user just bought a big box full of yammi cookies and than he has 2 take a crap for one hour...

I guess the update will fail,
and I also don't like 2 check if there is a replace 2 do on each
execution of MyApp.exe

it could B great if I could replace update.exe at the end of the update (without waiting 2 some human reply)

But how the **** do I close the Update.exe (installer)

I don't understand what's hard about closing the update.exe. In update.exe do

Exec MyApp.exe
Quit

Hay man, U got a good point here :-)

4 some reson I had in mind that if I execute from update.exe I can not also close it,

but I guess U right,
I'm just about 2 try this

Check the NSIS Update source (CVS), it copies itself to the temp folder and executes there (so it can update).
