The newer version 1.2 doesn't run on non-English systems (known problem). A workaround helped to fix the first errors with the installation, but there are other errors that don't allow an installation. For two hours I tried everything to get it working, but the only result I get are innumerable error pop ups. I have to give it up now, sorry. ------------------------------------------------------------------------ [2012-03-10 16:54:15] paj...@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2012-03-10 12:06:02] ziegenberg at web dot de Here is a crash report I found, perhaps this helps: ----- Version=1 EventType=APPCRASH EventTime=129758533564007575 ReportType=2 Consent=1 ReportIdentifier=214d7de4-6aa6-11e1-bd6c-4c8093870ef0 IntegratorReportIdentifier=214d7de3-6aa6-11e1-bd6c-4c8093870ef0 WOW64=1 Response.type=4 Sig[0].Name=Anwendungsname Sig[0].Value=httpd.exe Sig[1].Name=Anwendungsversion Sig[1].Value=2.2.22.0 Sig[2].Name=Anwendungszeitstempel Sig[2].Value=4f4a84ad Sig[3].Name=Fehlermodulname Sig[3].Value=php5ts.dll Sig[4].Name=Fehlermodulversion Sig[4].Value=5.3.9.0 Sig[5].Name=Fehlermodulzeitstempel Sig[5].Value=4f591617 Sig[6].Name=Ausnahmecode Sig[6].Value=c0000005 Sig[7].Name=Ausnahmeoffset Sig[7].Value=000a57a0 DynamicSig[1].Name=Betriebsystemversion DynamicSig[1].Value=6.1.7601.2.1.0.256.48 DynamicSig[2].Name=Gebietsschema-ID DynamicSig[2].Value=1031 DynamicSig[22].Name=Zusatzinformation 1 DynamicSig[22].Value=0a9e DynamicSig[23].Name=Zusatzinformation 2 DynamicSig[23].Value=0a9e372d3b4ad19135b953a78882e789 DynamicSig[24].Name=Zusatzinformation 3 DynamicSig[24].Value=0a9e DynamicSig[25].Name=Zusatzinformation 4 DynamicSig[25].Value=0a9e372d3b4ad19135b953a78882e789 UI[2]=C:\apache2\bin\httpd.exe UI[3]=Apache HTTP Server funktioniert nicht mehr UI[4]=Windows kann online nach einer Lösung für das Problem suchen.
