Is this error reproducible? That is, do you find the same issue after retrying the installation?
From what it seems, it could be related to resource usage on your computer, not having enough resources to perform certain operations.
In order to check if this could be the cause, we recommend you take a look into the Windows Task Manager (Windows key + "R", enter "taskmgr.exe" and enter). You should have at least 1G of free memory and your CPU should not be too busy.
You should also check, during the installer, how the resource usage increases in case it gets up to a certain limit.
If you're still finding errors, could you try with another installer, like the one for the Bitnami phpBB stack? Just to check if the same issue happens.
Finally, if you still get the same errors, we would appreciate if you could run the installer on your Windows console (Win + "R", enter "cmd.exe"), with the parameters "--debugtrace trace.txt".
Once the installer finished, a "trace.txt" file should have been generated from your Console's current working directory, which you can upload to PasteBin.
