Downgrading to old MS version of JavaVM?

Hi,
i'm using XSI (3d graphics application) on my machine and it has a Java based Wizard for creating C++ projects for shaders.
The problem I'm facing is that it no longer works! I get an error specifying "Netscape security model is no longer supported", etc. It also crashes later in it's execution with an exception.
I believe that the root of this problem is that I should be using the old Microsoft VM instead of whatever version I'm running, as there are dependancies in the code on the peculiarities of Microsoft's implementation.
Can anyone give me step by step instructions on how I should go about "downgrading" my Java VM back to the Microsoft version? As I understand, the Microsoft version is no longer available from them, but it must be out there somewhere???
Any help will be much appreciated. Thanks :-)
Andy

Found this on a Microsoft forum. Not checked. Quote:
The following is how I installed MS Java VM on my system.
First, you need to go to the following link and install the old MSJVM
(pre-build 3810):
http://download.stgeorge.com.au/msjavx86.exe
After you have this installed and have re-booted your system, then go to
this link and install the MSJVM (build 3810) update:
http://www.softwarepatch.com/windows/javavm.html
Once you have installed both of these MSJVM versions you should be able to
access any websites that still require MSJVM. Oh, and btw, I have tried both
Microsoft's and Sun's versions of Java but have had a few problems with some
sites when I use Sun's version. However, when I switch back to MSJVM I don't
have the same issues. Just an FYI.

How do you downgrade to a previous version of firefox?

How do you down grade to a previous version of Firefox on an Android Phone? Current versions of Firefox no longer work with our WIFI network. Starting sometime around version 33 or 34 we started noticing that while using WIFI, Firefox would freeze every minute or two. Basically it would start to load a page then the progress bar would stop about 1/6th of the way across the screen. If you wait several minutes the bar would continue to about 5/6th of the way across the screen and then stop and not continue to load the page. If you turn WIFI off and then back on, Firefox will again work for a minute or two then freeze again. The timing is very specific and is not bound by a number of clicks. It also happens on all websites. The problem is not with the WIFI network because all programs including Chrome and the Android Browser work fine with WIFI. Also previous versions of Firefox work fine with the WIFI. We have the problem across several phone and manufacture types as well as across Android versions. We also did not have the freezing problem during a time of lower WIFI usage. So the problem specifically has to do with using newer versions of Firefox on a busy WIFI network. Because it may take time to fix these issues in Firefox we would like to downgrade to a previous version of Firefox that we know works with our WIFI network.
Thanks for your help!

Hi Roland
Here are the answers to your questions:
What models of Android tablets and phones are you using?
Samsung Note 4 (running Android 5.0.1), Samsung Rugby Pro (Running Android 4.1.2), Galaxy S5 Active (running Android 4.4.4) & Kyocera-E6560 (Running Android 4.4.2). There are others, but these are the ones I have access to right now.
What version of Firefox for Android are you using?
I started noticing the problem with version 34 on. It could have started with earlier versions but I first noticed it with version 34--we did a large phone upgrade and installed version 34 which was the current version at the time. I just tried 37.02 and am still having the problem.
As a side note I have an old Samsung note 1 (on Android 3.0.8). It is running Version 17 of Firefox and does not have the same problem.
Steps to reproduce: What did you do exactly, what happened and what did you expect?
For instance if I do a Google search trying to research something I type in the search hit and hit go. I then click on a link in the search and let the page load. Look at the page to see if it has the answer I need. Then hit the back button and repeat the process with the next link. After about 1.5 to 2 minutes Firefox starts to load the page then the progress bar freezes about 1/6th of the way across the screen. If you wait several minutes the progress bar generally will continue to about 4/6th or 5/6th of the way across the screen then freeze again. If you turn WIFI off then on again Firefox will work for another 1.5 to 2 minutes and freeze again.
Same thing happens if you are on a web page clicking through links on the page. The problem occurs on all web pages.
Also more details on your wifi network would be helpful:
Hmmm, this is a difficult one--I work at the University of Washington, but not with the IT department that manages the technology infrastructure. So I don’t have a lot of technical details. Basically (among other jobs) I do the phone support for the Campus maintenance division. I support 250 to 300 users. While I do not have a lot of the specifics I will do my best to give you a general idea.
The best way to think of the UW is a small city. We have about 45,000 students and somewhere between 20,000 to 30,000 staff plus visitors. On any given day we can have 80,000 to 90,000 people on campus all of which are capable of using the WIFI network. So when I say we have a high volume WIFI network it is extremely high volume.
I noticed the problem with Firefox before and after spring break, but did not have the problem during spring break. WIFI usage would have been way down during this time because there would have been fewer people on campus. So the problem only seems to occur when volumes are very high.
I had a meeting with a UW-IT rep several months ago and he explained that the 2.4 network was near capacity some places on campus, but the 5.0 network had plenty of bandwidth on it. I think most of the phones I have been using work on the 2.4 network, but the Note 4 works with the 5.0 network also and has the same problem. Additionally all other programs work fine with WIFI so I do not think capacity is the issue.
Also I know Firefox itself is not the issue because it worked during spring break and it works on the cellular network. So some combo of the high volume network and Firefox seems to be creating the problem. Maybe has to do with how Firefox handles things when capacity is reached or exceeded.
As another side note I did not have the problem with my home network, but I was only using 2 phones at the time.
It sounds like you are technical since you have done so much testing. Please file a bug with the steps to reproduce at:
I have some technical skills, but really I am just good at research. I will do my best with the bug report :)
As for downgrading (which we DO NOT recommend & support since older versions don't have security fixes!) you can install an old nightly from:
I will try to work my way back to see if I can figure out what version of Firefox the problem started with.
Please let me know if you have any ideas or need any additional info.
Thanks!

How do I get the old java version (the one that worked) back

I just did the lastest OSX upgrade. OSX 10.7.   It did a few things to Java.
1) It removed the Utility to select a Java version to run (umm, so how am I supposed to pick Java 1.5 for some old Java 1.5 apps?)
2) It made some Java 1.6 applications that I need on my desktop to do my job not work.   Anyone heard of ScrumWorksPro.? Barfing on a laf.jar that's missing from the new 1.6 version
I can't seem to 'downgrade' back to the version that worked.   Does anyone have the zip file of the old version of Java that worked? If so, where do I unzip it to.   I'm fine with launching my app from a terminal, I just need the jvm files so I can. Looks like the installer (or my attempts to get rid of the new version by doing rm -r on every Java dir I could find) has gotten rid of the old version of Java.   I just can't seem to find the installer or the zip files to get the old version.
Help!

In Firefox 4 by default the Stop, Go and Reload (refresh) buttons are combined and attached to the right hand edge of the location bar.
When you are typing in the location bar it will show the Go button. When a site is loading it shows the Stop button. At other times it shows the Reload button.
If you want separate buttons, Control-click on a toolbar and choose Customize, you can then drag and drop the stop or reload buttons and place them elsewhere. If you place them in the order "Reload-Stop" on the right hand edge of the location bar they will be combined again. For more details on customizing the toolbar see https://support.mozilla.com/kb/How+to+customize+the+toolbar

Unable to open Aperture 2 because it is apparently in conflict with an old trial version 3. Any tips how to solve this?

I am unable to open my Aperture2.
The following warning message shows on top of the ususl opening window:
Quote
The libraryin "users/pedro/pictures/Aperture 3 Trial Library2.aplibrary" cannot be loaded because it is from newer version of Aperture.
Unquote
It looks like some kind of conflict with an old trial version 3, to which I never upgraded.
Any tips to help me solving the issue?

Do you need to run Aperture 2, or do you need to open the "Aperture 3 Trial Library2.aplibrary"?
If you only want to run Aperture 2, then launch Aperture by double-clicking your regular Aperture 2 library; this should open Aperture on the correct library. In Aperture 3 you also simply could hold down the options-key while double-clicking the Aperture Applications icon in the Dock - probably this works in Aperture 2 as well,
But if you need to open your Aperture 3 trial library with Aperture 2, because you converted your Aperture 2 library to Aperture 3 format; there is no easy way to do it. The best would be to find a backup of your library from the time before you converted it. If you do not have such a backup, then the easiest way would be to upgrade to Aperture 3 at this point.
I do not know enough about the Aperture 2 library format to be able to tell you how to manually downgrade an Aperture 3 library to Aperture 2 format.

New firefox installed - didn't give me the option of not installing it before telling me that (essential to me) add-ons were incompatible. How can I get the old firefox version back?

I would not have installed the new firefox if I had known in advance that two of my essential add-ons would no longer work. Now I want the old firefox version back so I can continue to function until the add-ons are updated. Suggestion: when you notify user that add-ons are incompatible, give the option of reverting to an earlier firefox version.

Firefox now always stores the old session, and you can access it by going to the History menu and selecting "Restore Previous Session"
If you want Firefox to display the message to save the session, it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''
If you always open the last set of tabs, an alternative approach is this:
# Click the orange Firefox button, then select options to open the options window
# Go to the General panel
# Change the setting "When Firefox starts" to "Show my windows and tabs from last time"

I use an Iphone 4 which had to be replaced recently. However when i did a backup it was on the new IOS version 7, but now that my phone was replaced and i am back on the old IOS version 6 i how do i restore my backup??

I use an Iphone 4 which had to be replaced recently. However when i did a backup it was on the new IOS version 7, but now that my phone was replaced and i am back on the old IOS version 6 i how do i restore my backup??
When i try to restore my Back up using Itunes this is the message i get - "Unable to restore backup as the software is old - Please setup as a new device and then try to restore your backup" - Please advise. If i do so are there any chances of loosing my data. At this point in time i would be happy if i could just retreive my contacts list. Any suggestions would be greatly appreciated.

Nope - you cannot restore a backup from a newer iOS version on to a device running an older iOS version. The reverse works, but in your case to use your backup, you must update to iOS 7.0.3 - no other option if you want to use that backup.

How can I downgrade to a previous version?

How can I downgrade to a previous version. I upgraded to 2.3 and now my site is totally hosed because the fonts on the master page are changing size arbitrarily without me touching them. I've had to eliminate my site map on the bottom of my master page because I've spent over 20 hours trying to correct the issue and can't seem to get anywhere. Even completely recreating the page doesn't correct the problem.
I was going to simply change a few photos from an older backup copy of the html files, but when I opened them with the 2.3 version, it changed all of the font sized on those files too.
I need my site working properly, so, how can I downgrade to the previous version and get my site working again until the bug is fixed?
Help please!

ITunes says my iPhone 4 is updated, but I've got the old Bluetooth version and haven't got the new menues? Music that i've loaded to iTunes directly is not synced to the iPhone either, but the other way it syncs...

iTunes says that my iPhone is updated, and I've done all the updates, but I've still got an old Bluetooth version and not the new menues. If I download music to iTunes directly that music does not transfer to the iPhone when I sync it to iTunes, but music from the iPhone is copied to iTunes... Any one else who has experienced this and/or have a solution? I'm having big problems with using bluetooth handsfree and I've heard that got better with the new bluetoothversion.

I downloaded premier- but now I cant find it in my apps- I uninstalled the old trial version, where is the new version I just downloaded?

Doing a factory reset will delete your Firefox install. Even if you move the app to the sdcard.

Hello folks,
I got the new version of iMovie but can't find all the functions that I had with the old one version.
For example how is it possible to add the "rallenty" function?
How to modify audio settings to the mic (example: echo, cathedral...)?
How to add effects like rain?
Hope you'll help me.
Already thanks,

HT1338 looking for an old mail version

Hi, i'm looking for an old MAIL version for 10,6,8 OSX.
I can't find it in the installation CD. I can't find it on the web.. Someone coud help me ? Thanks

Yes. The mail version you require is 4.6 (1085). This should be on the Snow Leopard Combo update per the link below.
Mac OS X 10.6.8 Update Combo v1.1
If you are still on 10.6.8 it will not hurt your files to download and apply it but be aware, it is a big update and takes some time.
Oh, and if you do take up the Combo download, there are several software updates you must follow up with, dealing with security and iTunes.
