Does it work for you? If so, I might embed it.
(I wonder why my Windows 10 has not complained then.)
Yesterdays research result:
I was not able to add/modify resource section of the .exe since it has none.
On my home pc all works fine!
My workstations Windows Defender is configured/fixed/static/unchangable to block "strange" files.
Testing as external manifest file isnt able aswell since I cannot modify system-registry.
If someone is interested, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide needs a sub-key PreferExternalManifest with DWORD value of 1.
Afterwards you can do things like "clipurlcleaner.exe.manifest" with content that Tuxman showed to have at least Windows XP look activated what is kinda pointless in that application.
I would suggest to add to that manifest Windows compatiblity and Access-Level "as Invoker".
