Bill: Glad to hear your better... I was preparing myself for a complete OS X reinstall after reading your earlier reply, hoping that maple tech support would come up with something else...but they finally came back with the recommendation for either a system restore or complete OS X reinstall. So I'll be doing an OS X reinstall soon...Thanks!!

Bill: It looks like I'll have to do clean install as well. I'm not finding any fixes that work. Would you clarify a couple of things for me though before I do a clean install? 1) check your systsm/library/framworks/javaVM.framework/versions folder and see if there is a folder named "A" and an alias folder named "Current". Does the alias folder Current point to the "A" folder? Mine does, and I thought that was the problem since a Discussion question I came across on J2SE 5 Release 3 said the "Current" folder should point to the 1.4.2 folder. (I downloaded and reinstalled the J2SE 5 Release 4 upgrade and it reinstalled the "A" folder...so that is not the problem). 2) When you did the clean install, then did you go get and install all of the system updates and security updates including 2006-7 and 2006-8? Then did you reinstall Maple 10 using the Maple 1006 upgrade installer (I got it from Maple tech support trying to fix my problem, but it did not work....thus I think I have to do a clean install of the OS X system)? Thanks!!

I cannot get Maple to start up. See the link--- http://www.mapleprimes.com/forum/maple10-on-mac-osx-not-working-after-memory-upgrade I have tried the latest Maple tech support direction of switching the order of preference of Java 1.4.2 and J2SE 5 in the Java Preferences utility, (then restarting the computer).... and this does not work on my iBook G4. I very recently upgraded my RAM by 1Gb and I am running OSX 10.4.8 with the latest security upgrades. I certainly can use any help on this...I don't know what else to try!!

William: Did you ever get your Maple 10 installation to work?? I too have the same upgrade versions as you. AlthoughI have been in contact with Maple tech support several times now, trying all their recommendations/directions and I still cannot get Maple to start. I keep getting the same error message as I did the first time. I followed their lastest directions: "This error message indicates that you are likely running Java 1.5. Please note that Maple 10 requires Java 1.4. There are 2 changes in the Java preferences window that will need to be made. First, select Java1.4 in the drop down at the top of this window. Next, in the list near the bottom of the window, drag Java 1.4 to the top of the list. Click save then try opening Maple 10." and this still did not work.

Yu-Hong I Spotlighted my computer and found only one instance of the maplelcient.jar file. Its in the directory /Library/Frameworks/Maple.framework/Versions/10/java folder. To confirm the moving of this file to the desktop, I did so and clicked the Maple10 icon to launch it...I got the same error message in the Console (see earlier post) and the following message "Failed to load Main-Class manifest attribute from /Library/Frameworks/Maple.framework/Versions/10/java/mapleclient.jar" I then move the mapleclient back into the java folder and tried to launch...getting the same error message as before, but without the above reference. What's left to try??

Thanks for the suggestions....I tried the command line with the -x, but Maple will not start up. I'm thinking its a Java problem as you since the Console log shown pointers back to the java files. I have OSX 10.4.8 and have re-checked that I have the latest system upgrades. I have also re-installed the 10.06 upgrade, but Maple still will not startup in GUI. I've sent Maple Support a couple of emails and await their help. I have not uninstalled Maple and reinstalled it, thinking this may be Java related. I may have to do this though.... is the first line or two of the Console log (see earlier post) indicative of a java problem??

Thanks! Yes, I can run Maple in command line mode. I copied/pasted the command line as written and right away got the Maple line splash output! Any thoughts on why Maple won't start with the GUI?

In viewing the Console I see the following message as a result of attempting to run Maple 10. What is causing this? [LaunchRunner Error] com.maplesoft.worksheet.application.WmiWorksheet.main(String[]) threw an exception: java.lang.NoSuchFieldError: MAPLE_MAJOR_VERSION at com.maplesoft.mathdoc.platform.WmiPlatformFileTools.(Unknown Source) at com.maplesoft.worksheet.model.WmiWorksheetPropertiesManager.populateProperties(Unknown Source) at com.maplesoft.worksheet.model.WmiWorksheetPropertiesManager.(Unknown Source) at com.maplesoft.worksheet.model.WmiWorksheetPropertiesManager.getInstance(Unknown Source) at com.maplesoft.worksheet.application.WmiWorksheet.setupLocalization(Unknown Source) at com.maplesoft.worksheet.application.WmiWorksheet.main(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at apple.launcher.LaunchRunner.run(LaunchRunner.java:88) at apple.launcher.LaunchRunner.callMain(LaunchRunner.java:50) at apple.launcher.JavaApplicationLauncher.launch(JavaApplicationLauncher.java:52)
