Photoshop CS5 32 Bit Installation Errors, Windows 7 Ultimate

Question

Today I did a second install of Photoshop CS5, in a 32 bit Windows 7 virtual machine that is otherwise in fine health (up to date, yada yada).
The Photoshop installer package I had used prior to do a perfectly successful installation on my x64 Windows 7 system didn't have quite as good luck on my 32 bit system...  It wouldn't do a default install at all, and even when I disabled UAC and configured all the options disabled (no need for 'em for my testing), it still emitted some errors - though in the latter case it actually completed the Photoshop installation and I was able to run Photoshop.
Note that after the first failure I disabled UAC.  All installs done from an administrator account, though I did not run the installer as administrator while UAC was on.
This is not a big deal - what I needed to test with did finally get installed, but I thought Chris or someone at Adobe might like to know what the installer barfed on.  Here's what it reported:
First install, failed utterly:

Answer 1

This is for people who might find this thread via a search:
The errors I reported above (e.g., those with the .otf fonts) are related to the configuration of the "3 gigabyte address space" option, invoked by the switch /3GB in boot.ini (XP) or bcdedit /set increaseuserva 3072 (Windows 7 and Vista), which is what I was experimenting with when doing this installation.
I dropped back to the default 2 GB setting (bcdedit /set increaseuserva 2048) and tried a reinstall to confirm, and indeed the install went through smoothly.
Trying to increase your address space in a Windows 32 bit operating system through tweaking has known downsides; consider moving up to an x64 operating system instead to be able to access more RAM.
