I would suggest that you contact Maplesoft Technical Support and they can probably help you out with this.

Otherwise, some more information like what operating system and Java version you are using would be helpful.

You are near the bottom of the system requirements in regards to your CPU and well below the 2 gb of RAM, which may be a factor. To increase the Java memory allowance on a Windows computer, you will have to change the maximum Java heap size memory setting by editing the launch.ini file.

1. Navigate to your Maple installation folder. (“Start Menu”>”My Computer”>”Local Disk (C:)”>”Program Files”>”Maple Player”)
2. If you have a 32-bit Maple installation, go to Maple Player’s “bin.win” folder.
   If you have a 64-bit Maple installation, go to Maple Player’s “bin.X86_64_WINDOWS” folder.
3. Right-click on the file “launch.ini” and select “Open with…”.
4. Choose “Select the program for a list” and click OK.
5. Choose a text-editing program (e.g. WordPad) and click OK.
6. With the “launch.ini” file open, find the following lines:
   #set maximum Java heap size
#maxheap=700m
7. Delete the “#” and space character that precede the word “maxheap=700m”. This leaves a final line stating:
   #set maximum Java heap size
maxheap=700m
8. Save the file and launch Maple Player.

Note that this change will not affect the amount of memory available to the non-Java components of Maple (e.g. the math engine), which will still take advantage of the machine’s internal memory when solving large problems.

The convert command with the unit_free option will remove any units placed on a variable.

Firstly, it should be noted that we do not support the use of your Maple version on Windows 8.  Even if you are able to get it to install, we cannot guarantee that Maple will run properly on Windows 8.

That said, the “installer user interface mode not supported” error message is something that we have seen before and you should be able to work around the issue by doing the following.

1. Right-click the installation file and select “Properties”.
2. Click the “Compatibility” tab.
3. Check the box next to “Run this program in compatibility mode for” and select ”Windows 7” from the drop-down menu.
4. Click “Apply”.
5. Right-click the installation file and select “Run as Administrator”. You may then continue through the installation as normal.

This should correct the issue, but again, please be advised that we do not support the use of your Maple version under Windows 8.

This sounds like it might be a problem with your license file and I would advise you to contact Technical Support (support@maplesoft.com). They should be able to help you with this issue.

The plotting regression bug may be fixed using the mathdoc.jar update posted here:

Edit: The 16.02 plotting bug has been fixed in the 16.02a update that is available on the Maplesoft website here:

http://www.maplesoft.com/support/downloads/m16_02a_update.aspx

With this update, you no longer need to use the fix below and the jar file will eventually be removed. These instructions remain only for documentational purposes.

--------------------------------------------------------------------------------------------

Unfortunately the line not being displayed in the plot is a result of a graphing bug present only in Maple 16.02. This bug has been fixed for the next version. Until this next version is released, we recommend that you replace the 16.02 version of the mathdoc.jar file with the following mathdoc.jar file.

ftp://public.maplesoft.com/Previous%20Installers/16/java/mathdoc.jar

To replace the mathdoc.jar file, please follow these instructions:

For Windows users:

1. Right-click the download link and choose “Save link as” to save the file to your Downloads folder.
2. Open your Downloads folder. You may do so by clicking “Start Menu”>”Documents”, then in the left side bar, click on the “Downloads” folder.
3. Open Maple’s “java” folder in a new Explorer window. You may do so by clicking “Start Menu”>”Computer”, then in the new Explorer window, click “Local Disk C:”>”Program Files”>”Maple 16”>”java”.
4. Rename the current “mathdoc.jar” file in Maple’s java folder to “mathdoc.bak”.
5. Copy the mathdoc.jar file from the Downloads window.
6. Paste the mathdoc.jar file into the java folder. Maple is now patched.

For Mac users:

1. Right-click the download link and choose “Download Linked File As..” to save the file to your Downloads folder.
2. Open your Downloads folder. You may do so by opening Finder, then in the left side bar, click on the “Downloads” folder.
3. Open Maple’s “java” folder in a new Finder window. You may do so by clicking ”File”>”New Finder Window”. With the new window open, at the top of the screen, click “Go”>”Computer”. Navigate to Maple’s java folder by clicking “Macintosh HD”>”Library”>”Frameworks”>”Maple.framework”>”Versions”>”16”>”java”.
4. Rename the current “mathdoc.jar” file in Maple’s java folder to “mathdoc.bak”.
5. Copy the mathdoc.jar file from the Downloads window.
6. Paste the mathdoc.jar file into the java folder. Maple is now patched.

For Linux users:

1. Right-click the download link and choose “Save link as” to save the file to your Downloads folder.
2. Open your Downloads folder. You may do so by opening the File Explorer, then in the left side bar, click on the “Downloads” folder.
3. Open Maple’s “java” folder in a new File Explorer window. You may do so by clicking ”File”>”New Window”, then in the new  window, click “home”>”maple16”>”java”.
4. Rename the current “mathdoc.jar” file in Maple’s java folder to “mathdoc.bak”.
5. Copy the mathdoc.jar file from the Downloads window.
6. Paste the mathdoc.jar file into the java folder. Maple is now patched.

With the new jar file installed, you should no longer observe the missing line issue.

If you would like to print off your parameters, you may do so using the Excel Connectivity template. This will export your parameter sets to an Excel spreadsheet in an easily viewable format that you may then print out. To do this, please use the instructions found on our website:

@andrewfortune Can you try to open Maple using a saved Maple worksheet file (.mw)?

The maple.exe program will be running in 32-bit mode as it is primarily the graphical interface and will not necessarily benefit from running in 64-bit mode and can infact be slower than an equivalent 32-bit version.

The worksheet calculations are being performed in the mserver.exe program, which will be running in 64-bit mode, and this is where the difference between 32-bit and 64-bit is important. In other words, all is working as intended.

Unfortunately you will not be able to find a copy of Maple V online as it came out in 1996 on 3.5" floppy disks and will only run on Windows 95 systems. You will have to purchase a new version if you wish to run Maple on any modern system, or dig out the old disks if you have a Windows 95 machine hanging around.

If this is a Windows laptop, you will need to uninstall Maple from the old hard drive, and then contact Maplesoft Customer Support to have them deactivate your old license file. This will allow you to install and activate Maple on the new hard drive once it is installed in your computer.

If this is a Mac or Linux laptop, you should uninstall Maple from the old hard drive before replacing it, and then you will be able to install and activate Maple on your new hard drive with no problems.

Were you able to solve this problem Srinivas?

Could you post the code that is causing the error? It is difficult to diagnose the problem without seeing what might be causing it.
