Since NickJW is also using it without compatibility mode without problems, maybe you could try that first? Otherwise, have a look at Mortal's signature. There you'll find the installer version of ZAZ tools for download.
That reminds me: My Windows Defender was activated after the Win10 upgrade, although I had deactivated it in Win7. The first thing it did was flagging a file from another game. So maybe check the Windows Defender, too, for files that it might have been flagged. Also check other antivirus software for that reason. Possibly, any of those just flagged a file needed for ZAZ tools and it's common knowledge that there are one or two files in ZAZ tools that are mistakenly flagged as viruses by some antivirus softwares.
