So, looking through the first few pages of the tech support forum, I see that there are a handful of threads made by people getting an 1152 error when trying to install the game. I have been trying repeatedly to install for the past several days and have been getting this error no matter what I've tried. I have already tried the solution provided by Matt here to no avail. I've tried everything I can think of to install this program yet I get the error no matter what. I see from the sticky that the game apparently has trouble with Windows 8- is that what is causing this? If anyone can offer any possible solutions to this problem, your help would be greatly appreciated!
I don't know what specifically you have tried, but I would recommend disabling your antivirus, download the Setup, run the setup, and only then reenable your antivirus. More often than not, it seems that the antivirus is the culprit in preventing people from installing MapleRoyals on their computers.
