String Search and Replace

Using NSIS, I would like to know how to
do a search and replace.

Say, I want to search for "\" and replace with "/"
for a file path.

Let's say my $INSTALLDIR
is "C:\MyPath\Install"

I would like the resulting string to be
"C:/MyPath/Install"

How would I do this?

Thanks in advance.

In the Nsis Archive there are some goodies about strings:

Wow!

The StrReplace examle found in the NSIS Archives works great!

Thank you so much!
