Tip #3 - I have installed these programs on dozens of computers. Once I got the following error on a Win XP system when trying to download a self-extracting file:

So like a good programmer, I just started emitting a bunch of random behaviors.

• I tried to save the file to disk and received a similar error.
• I tried to open it from the Internet - still same problem.
• I tried saving it as a different name - and then running it - still same problem.
• I tried to install it on another XP system (because I thought there might be administration priv's issues) - It installed fine on that machine.\
• Then I tried to install it again on the system that was giving me problems and it work that time.
• I say this because sometimes you just need to try different things (including lettingit set for spell).
