Thank you,
 
	I do believe that it is an x86 application, that must be the issue.
 
	EDIT: I've also made a firefox installer (Version 79.0B9)
 
	I opened up the firefox.exe file in  CFF Explorer and set the entry point in ntdll.dll from RtlQueryPerformanceCounter to NtQueryInformationProcess
 
	and it worked perfectly fine. It runs perfectly! I also credited Win32 in the installer.
 
	 
 
	I hope you find my installer useful
