Interesting. Seems like it might be a SSD only problem. I might also consider re-installing GW2 on my SSD in the future, so if indeed this is a problem it would be nice if it is fixed. SSD, 48gb here. Nice, I guess it will be fine for me to download again onto my SSD then. Not sure why the OP is having a problem installing on their SSD then. I assume that you only need the required 48 GB of space free on the SSD to be able to download and install the files, unless there is some compression done of the game files after installation? BTW You don't need to download it again. You can just move the gw2 folder and all its contents to a folder on your SSD, update your desktop shortcuts to point to the new location and it should work fine. Lo and behold I've found the issue that was doubling the size of the GW2 folder, and honestly everything else I move to that drive. I'm no expert on Windows or hardware/software, but it turns out that moving files from an uncompressed drive onto a compressed drive doubles the storage use of that file. The remedy I've found is that I simply uncompressed my SSD, and copy-pasted GW2 onto the SSD. Issues in Windows forums have come up before dealing with this.
