Similar symptom to bug 105470 http://sourceforge.net/tracker/index.php? func=detail&aid=1085208&group_id=5470&atid=105470 Running python-2.4.1.msi with all default setting. It ends quickly with a dialogbox titled "Python 2.4.1 Installer ended prematurely". Same problem running the 2.4 msi. Machine information: Windows XP Professional V2002 SP2 Dell Latitude D600 640MB RAM Symantec Antivirus 9.0.1.1000 (disable it does not help) cscript.exe version 5.6.0.8825 (upgraded from 8820?) The workaround mentioned in 105470 does not help. Running x.vbs gives me 0. Doing regsvr32 c:\windows\system32\scrrun.dll makes no difference.
Logged In: YES user_id=561546 Problem solved: I copied the msi file to the root directory (e.g. c:\) and launch from there. it works prefectly. I found that not only Python installer gave me problem, any msi installer gave me problem on this machine. Then I found the clue from Ultramon's FAQ: http://www.realtimesoft.com/ultramon/support.asp#2
