Cannot install InDesign Trial on Mac (10.9.5)

Question

Hi All
For the past 2 days, I've lost count of how many times I've downloaded and re-downloaded a trial version of InDesign. All I wanted was a working 30-day trial, but it's turned out to be quite a nightmare. I wanted to at least get a trial, before splurging all the cash for the full version... but at the moment I'm glad I didn't blindly just buy it outright!
Initially, I downloaded a CS6 version. Downloaded from: https://helpx.adobe.com/x-productkb/policy-pricing/cs6-product-downloads.html.
This gives 2 files:
InDesign_8_LS16.dmg, and
InDesignFamily_8_Content_ALL.dmg.
Opening the first .dmg gives me a error message, saying it cannot be installed on my system, and that I should use Adobe Support Advisor:
Following the link provided, I discover that Adobe Support Advisor has been discontinued:
I then go back to http:adobe.com/au/downloads.html and click the InDesign CC link. This forwards to creative.adobe.com/products/download/InDesign.
This downloads CreativeCloudInstaller.dmg.
I double-click and open the installer, enter my admin p/w and the installer begins, and then fails. Error:202
Doing a web search brings me to:

These provide links to suggest that I change my folder permissions in ~/tmp (which already has full permissions). Additionally, Error:202 (according to the Adobe list of log errors) states 'there is a problem downloading updates to the location specific in preferences. Change the path and continue.'  The solution then states 'download the update from Adobe.com and install.'
What is this 'update'? Where do I find it?
Another thread, https://forums.adobe.com/thread/1497278 provides a multitude of links to other threads, the first handful are regarding the Creative Cloud Cleaner Tool. I download the cleaner tool, and run it, only to get an error message:
But if I mount the .dmg, it loads and tells me that there are Adobe ID Credentials that can be cleaned. So I clean them.
It also suggests restarting my MBP and trying the Creative Cloud Installer, which I've done and had no luck.
I've also followed suggestions of verifying and repairing disk permissions (which I've done) as well as restarting after each install and each uninstall (which I've also done), but still can't get it to work.
I'm running a Macbook Pro / 2.3 GHz Intel Core i7 / 8GB RAM / OS X Mavericks 10.9.5 (13F1077) /
Welcome any and all suggestions you may have!!
