I am getting a dialogue box on startup stating explorer.exe - Entry Point Not Found x The procedure entry point SHCreateThreadRef could not be located in the dynamic link library SHLWAPI.dll OK and then it will sit at the desktop wallpaper with nothing else happening, it will respond to Ctrl-Alt-Del but not much else ... and ideas or suggestions as to why this might be? or indeed a method for launching the uninstall procedure from a run command? Edit 1a: I am re-running the installation program to see if it has any effect. Edit 1b: Same result Edit 2a: BTW way is there a command line to restoring to a restore point? Edit 2b: c:\windows\system32\restore\rstrui.exe Edit 2c: hasn't worked, I'll go back even further with my restore point and try again (this means that it may not have anything to do with XPize 4.0 beta 2 and just coincidental that it occured after the beta was installed - my apologies but any suggestions would be welcome) Edit 2d: the restore from yesterday's point created for a automatic system update has fixed the problem, this may be the fault on it's own, or it may be a combination with XPize, I will try and recreate the problem. Edit 2e: reinstalling XPize 4 beta 2 Edit 2f: after reboot the same symptoms manifest themselves, I'll system restore to pre-installation again and see if it starts working again Edit 2g: the system restore to remove XPize 4 beta 2 has brought my machince back to functionality Edit 3: Well for me at least this latest version isn't working, of course I am quite happy to preform any tests and answer any questions about my system and it's configuration to get this sorted, but I'm off on holiday in 24 hours so make it quick , at least now I know I can get it back working again.
