I can´t install my own product

I said to myself, I'm not going to do it. The Mac is a "home" computer, and I don't want to "work"from it.  I want to do the fun stuff, like this:But after a couple of days of fun, Ithought it might be useful to be able to blog from the new iMac.  So,I did what you would do -- I surfed over to the downloadson IBM developerWorks:Lotus anddownloaded the trial of Lotus Notes 6.5 for Mac.  Easy enough.Problems cropped up immediately.  Thedownload comes down in .HQX format -- requiring Stuffitto unpack (which is not installed by default -- I learned that like thePC, .ZIP is the standard compression format for Mac users now).  Stuffithas a brain-dead installer, too, and requires a Mac reboot for proper operation(strange, I thought this was a Mac!); I tried to unpack the .HQX severaltimes before learning this.  After reboot, things weren't much better-- the HQX unpacked partially, then asked for a "decryption passphrase". What the heck?I tried both the 6.0.x and 6.5.x versionsof the Notes Mac trial -- neither would unpack.  Thus, I'm bloggingback on my Thinkpad right now.  I've installed other programs thismorning -- Firefox and Skpe were both relatively painless.  And mosteverything about the Mac has been easy so far.  Just not my own product. And yes, I know, once I get it installed, I get to deal with fontissues and all the rest.  Guys and gals, Macheads of the world,I feel your pain, no need to pile on.  In the meantime, can you tellme the secret handshake to install my own product?
