Additional requirements for FF 42 - 48 and KM 76: Dll's from XPSP2 or SP3 (or ReactOS) (Activeds.dll, adsldpc.dll, apphelp.dll, authz.dll, dbghlp.dll, dnsapi.dll, mprapi.dll, netrap.dll, netui0.dll, netui1.dll, ntdsapi.dll, ntlanman.dll, rasdlg.dll, rasman.dll, regapi.dll, rtutils.dll, samlib.dll, utildll.dll, w32topl.dll, winscard.dll, winsta.dll), MDAC2.8SP1 (Odbc32.dll, Odbcbcp.dll), GDIPlus.dll (for KM76) and Kext (latest Kstub823, ini file here). The names of all missing files were found with the DependencyWalker (DW). To do this open the Xul.dll with the DW. Missing modules are marked with a question mark in yellow circle. To get all names you must refresh or restart DW after adding files. New (missing) files will appear. The new files bring up new dependencies. You have to repeat the procedure several times. I have these files, XPSP2/SP3 and some from ReactOS 0.4.0, in the system folder. You also can try to paste them in the KernelEx folder, or KernelEx Subfolders like ROS, as KernelEx-KnownDll's. In this case (KernelEx-KnownDll's) is the registry entry in the Key [HKEY_LOCAL_MACHINE\SOFTWARE\KernelEx\KnownDLLs] necessary. Or paste them into the program folder, when you're afraid.
To bear in mind pdh.dll, psapi.dll, userenv.dll, uxtheme.dll and wtsapi32.dll are already supported by KernelEX (KernelEX-KnownDll's).
Don't merge LZDLL_ME.reg or LZDLL.reg for Win98 of KernelEx update18 into the registry! Firefox will crash immediately on start .
The portable Installer requires the apphelp.dll. It make sense to install the WindowsInstaller 12.0.2600.2, but I haven't testet it as requirement.
Direct3D9 (OMTC):
1. Install DirectX 9c
2. "layers.acceleration.force-enabled" => true - OMTC requires hardware acceleration!
3. "layers.offmainthreadcomposition.enabled" => true (default value)
I did all the tests with the portable versions and I only testet with NV7800GT and NV7900GS cards and drivers 82.16 and 82.69 on WinME This may not work with other hardware.
