Installation and Requirements
Make sure that you have a stable and performance friendly game.
It is higly recommended to install ENBoost. Holds uses a lot of memory and might crash unless ENBoost is installed.
Check out the STEP guide on how to install ENBoost.

Add:
[Memory]
DefaultHeapInitialAllocMB=768
ScrapHeapSizeMB=256
in SKSE.ini to make sure you don't get infinite loading screen.
I advice installing the mod manually. I have no experience with the mod installer tools and therefor I cannot be much help, and there have been reported many problems from mod users when installing with these tools. What is important is that Holds is loaded last, the only thing that should be loaded after Holds.esp should be its compatibility patches and alternative performance patches. So an example:
Skyrim.esm
Dawnguard.esm
Hearthfire.esm
Dragonborn.esm
SkyrimFloraOverhaul.esp
Holds.esp
HoldsSkyrimFloraOverhaulCompatibilityPatch.esp
