I just want to point out that it's not necessary to rebuild Emacs in order to change the embedded manifest. You just need the tools and the target executable. You can extract the current manifest to a text file. After changing or adding what you want to the text file, you can update the embedded manifest in the target executable.

Something like:

mt -inputresource:emacs.exe;#1 -out:extracted.manifest
... edit extracted.manifest ...
mt -updateresource:emacs.exe;#1 -manifest extracted.manifest

Note that the syntax of mt is inconsistent w.r.t. whether there is a space or colon after the option. See the docs for details.

(Sorry, but I have no idea whether adding Windows 10 as a supported OS will help with the problem.)

Hope this helps,

I copied mt.exe and the 24.5.1 emacs.exe to the desktop on my Windows 8.1 computer. Observe result:

C:\Users\HP\Desktop>mt -inputresource:emacs.exe;#1 -out:emacs.manifest

C:\Users\HP\Desktop>mt -updateresource:emacs.exe;#1 -manifest emacs.manifest
invalid value for uiAccess in string: level="asInvoker"/
invalid value for uiAccess in string: level="asInvoker"/

Here is what the file looked like after I edited it:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

However, the "invalid value for uiAccess" error occurred whether I edited the file or not.

I have no idea what string I should try to pass in the manifest file instead of "asInvoker".

There were additional complications. I tried it first on my Windows 8.1 desktop with the 24.3.1 emacs.exe I have installed there. It turns out that its manifest does not even have OS compatibility indicators (just "win32"); so, at first, I thought the whole thing might be irrelevant. Then it occurred to me that maybe 24.5.1 was different. However, I could not get mt.exe to work on Windows 10. It complained about 2 missing DLLs. I secured those, and then it was complaining about something else; so I gave up and copied the 24.5.1 emacs.exe to the desktop on my Windows 8.1 machine. And, as it turns out and much to my surprise, it does have the OS compatibility indicators. But then the update of the manifest failed anyway. (The failed update leaves the manifest in a corrupted state.)

Any more ideas?

David V.
