I have messed my Abcpy.ini and now everytime i install illustrator using the script above, illustrator prompt me to enter the serial number, (I am using the autoit script mentioned above), what is weird for me is that if i try to install it by double clicking the Illustrator.exe which is the autoit file it installs perfectly without interruption but if i am doing it from an unattended xp it hungs on this windows "The following information must be entered before installation" when i enter my serial number, the autoit script continue normally below is my Abcpy.ini ;*************************************************************** ;Adobe Installer External Configuration File: Abcpy.ini ;*************************************************************** ;*************************************************************** ;Main Section ;The (Product) key is a required key ;*************************************************************** [MAIN] Product=Adobe Illustrator CS2 AbcpyVersion=2.0 ;*************************************************************** ;OEM Installation Options ;*************************************************************** [OEM Install] SERIALNUMBER=XXXX-XXXX-XXXX-XXXX-XXXX-XXXX USERNAME=Nakkoush COMPANYNAME=Home INSTALLDIR= ARPHELPLINK= ARPHELPTELEPHONE= ARPNOMODIFY= do i need to put the serial number in this format? SERIALNUMBER="XXXX-XXXX-XXXX-XXXX-XXXX-XXXX" or maybe the sequence has to be the same as illustrator asks which is: [OEM Install] USERNAME=Nakkoush COMPANYNAME=Home SERIALNUMBER=XXXX-XXXX-XXXX-XXXX-XXXX-XXXX Thanks in advance
