Our computer are HP Z220 workstations with 32 GB of RAM, a 128 GB SSD system drive (C and a 1 TB SATA drive (D. The problem we had was that IDS 2014 would run and die after a while and then roll everything back, or it would just launch and die and do nothing at all. We tried everything from turning off anti-virus, cleaning out TEMP folders, cleaning up registry keys and running every known 3rd party unininstall utility. Nothing worked.
The machines had Hibernation turned on, but even after it was turned off, the hibernation sys file remained and was eating up just enough room to cause the installs to fail. We opened a CMD prompt using "Run as Administrator" and ran "POWERCFG /HIBERNATE OFF", rebooted and now the installs are working fine.
Some machines also required throttling the Page file size down as well. We could technically kill swapping on the C: drive but some apps seem to have issues with that, so we knock it down to the minimum based on the overall size.
Though I do recommend turning off Hibernation, as I recommend in my space saving KB link, I do not recommend turning down the VM setting. Generally this should be set to 1.5x-3x the physical RAM. You'd likely get better results moving it to another drive than your system drive. So if you have two hard drives, put it on the 2nd one.
