In August I got a new laptop with Windows 10. My old laptop (which ran windows 7) had absolutely no problem running this game.

For the first time with this computer last night I tried to load MoE, and I've come to problems.

Firstly, it seams to be in an offscale window, not full screen, and nothing I can think of changes this. Then, when I click on anything, I get the Mask of Eternity has stopped responding message and the game crashes.

this image is how the main title screen shows up:

Hopefully someone will be able to help you with this. The King's Quest forum on GOG has posts from people who got Mask of Eternity running on Windows 10, so apparently it isn't a lost cause.

Thanks Marian. I did post on there too. I saw one post on there that said all they had to do is run in compatibility (which is mostly how I had to do it on my W7 computer) but so far even that isn't helping

Did you see the answer from nicode here?

Thank you SO much Jenny. I installed both the kqmoevol and the kqmoefix from the link Nicode put in that gog link, and it worked perfectly

I know MoE get's alot of flack, but it is one game I do enjoy

Glad the fix worked for you.

And now I have come to an odd freezing/halting.

I am entering the Dimension of Death after getting the illumination spell from the wizard. The sound cuts out and the game freezes. I have a save from just before the portal, and have closed down the game 3 times and opened the save but the same thing happens every time

Maybe it didn't fix the problem after all then. :(

I don't know what to do about it except maybe try to contact nicode like this person did...

Maybe try one of the saved games here

Good news! I thought I'd try something. I backed up my save since none of the ones in the sierra help site is at the spot I'm at. Then I fully uninstalled MoE and then reinstalled it and reapplied Nicode's fix and copied over my save to the install directory. I loaded the save in the game and I no longer have the problem

Congratulations on finding a fix for it.
