I have tried to download and install the game twice and keep getting the same "installation Failed" error, has anybody experienced anything similar?

Me too :). And I tried to restart my laptop, redown the game,,, However, they still didn't work.

Same here,

I have the same issue

On one computer game works fine, on other two instalation fails without any othere error message. Also Galaxy has some problems wiht it, since it is not able to uninstall it and repeats to say that instalation has failed.

Support told me to stop the installation and then go for more => Manage Instalation => import Folder

There I choosed the Forstpunk folder where I downloaded the game into and now all works fine

I met the same problem. I tried to open the starting procedure directly from the file where I download the game,It worked at the beginning but soon crashed.

Same problem. Tried close galaxy and reopen. Tried repair game folder. Nothing...

Edit:

Close Galaxy, reopen
Go to games > Frostpunk
Click More > Manage Instalation > Chose Folder
Select [GOG Games folder]\frostpunk
Done, worked

Same issue, this fix worked. They really need to patch this up.

I am having the same problem, installation failed, nothing works. The fix will not work because the import folder option is greyed out, and I can't choose it.
