Why won't this install?

[SuperCyborg33]

Every time I try to install StepMania it comes up with this:

Error opening file for writing:
"C:\Program Files\StepMania\Announcers\instructions.txt"
Hit retry to retrywriting the file, or
cancel to abort installation

This has happened with every mirror site I've been to. Why won't it let me install SM?

RE: Why won

Try re-downloading SM then installing it again.

I've redownloaded from every mirror multiple times and it always comes up with this.

Well here is the text file in question, see if manually putting this in the directory helps.

Edit: gah tried to attach before I realized what I was doing. Anyways, here is the text for the file. Just throw that in a new textfile instructions.txt and put it in the dir before you install.

Place announcer folders in this directory. See the readme for more details.
If you want to make a new announcer, copy the announcer "Empty", rename the
copy, and add your own sounds.
