<br>
Has anyone experience suggestions with writing self updating binaries<br>
for windows ?<br>
I have a small utility that I have to install on two "unmanaged" pc's,<br>
I would like to let the program check an url, for new versions, download<br>
a new versions,<br>
some how check that the program is valid (with a build in key, or<br>
certificate) and replace itself when necessary.<br>
<br>
Has anyone already done this in Haskell? Any suggestions, links ?<br>
<br>
Thanks,<br>
<br>
Pieter<br>
