No problem here with 64-bits Windows 7 OS Anyway it is SFX selfextractor, so there should not be any problem. Just doubleclick on Make_PE3.exe should work. I don't know what is causing your problem ..... Hmmmm....I'm not sure what would be causing that either. I'll have to try it out on another system that has a 64-bit version of Windows 7. If that doesn't work for me, I'll just extract it in Windows XP Mode and copy the files over. Thanks for all of your help. I figured out what was happening on the computer I was trying to extract on. McAfee VirusScan was stopping it. After I disabled the McAfee services, I was able to extract successfully. On a different note, I might be able to contribute a little. I figured out how to start PE Network Manager and close it when done. I used an AutoIt script to accomplish this. Below is the code that I used. ;Disable AutoIt System Tray Icon TraySetState(2) ;Disable keyboard and mouse while PE Network Manager is running to prevent user clicking off of main window BlockInput(1) ;Start PE Network Manager Run(@ProgramFilesDir & '\PENetwork\PENetwork.exe') ;Wait for the main PE Network Manager window to be active WinWaitActive('PE Network Manager 0.56', 'Network Drives') ;Close the main PE Network Manager window WinClose('PE Network Manager 0.56', 'Network Drives') ;Re-enable keyboard and mouse BlockInput(0) I then named and compiled it as NetStartAndClose. After that, I copied NetStartAndClose.exe to the PE Network Manager program files directory and added the lines in the code box below to startnet.cmd after the following line: :: start "Audio Fix PE3 - Wait ...." /wait "%SystemRoot%\System32\audio_fix.cmd" :: start "PE Network Manager" and close when done "%programfiles%\PENetwork\NetStartAndClose.exe" Hopefully, this helps some people out.
