what happen to registry when reinstall a software?

just a stupid question,

I have a software installed few days ago (mIRC for example),

and i forget about that and reinstall the same software again.

what will happen to the registry, will there be Double entries for that
software?

and if i want to uninstall it, do i have to do it Twice?

No, the installation will overwrite the previous entries.

No, you only need to do this once.

It depends on what the program was and how and where it was
installed. You *probably* (but not necessarily) installed it over
the top of itself, and there should be no problem.

If you have two copies of it installed, yes. If not, no.

If the installs went to the same place (defaults during the install), then
there is only one copy there; it was simply overwritten. Uninstall will
remove it all as well as the software author wrote the code to remove.

If you installed it to different locations, as in you chose something other
than the suggested default location during install, then it might leave more
craplets behind when you uninstall, but the first uninstall will likely be
all you need. The uninstall would likely take out some or many of the
"common" files and the files stored in the default locations (even though
you chose a different location, not ALL the files went there & thus the
Registry might still know about both locations), and a second
uninstall -might- not even be possible, or would claim there is nothing to
uninstall.
If it has its own uninstall program, you -might- be able to run that
successfully in each of the two locations, but it's not a big deal.
You might be left with the old folders still there and they could be
deleted, but what's left behind in the Registry is not likely to bother
anything.

Since you asked the question in the way you did, I suspect you probably
double installed to the same default locations, so rest easy.
