You may freely download and install the current release of Cvt2Mae. We recommend downloading the stable current release, however we may from time to time make available a beta release while we are testing new features and bug fixes. If you have previously installed Cvt2Mae and you want to update just the Java .jar file, you can do this as described in Section 1.3 below. Press the download button to start the install process.
Download and Install Cvt2Mae.
2. You start the download process when you click on the installer for your computer platform. (You may alternatively use the default installer discussed below.) Follow the directions it provides as you download the installer. It also provides instructions in the "View" hyperlink adjacent to the operating system you selected that tells you what to do after you finished the download. Part of the installation consists of telling the installer where you want to 1) put the executable installer (a temporary directory where you have lots of room is a good choice), and 2) the "installation" directory where you will typically leave the distribution after the installer unpacks it.
We use the commercial InstallAnywhere(TM) program to create the installer which are programs for a vareity of operating systems including:
The default installer will put the installer executable in a fixed directory and the installed Cvt2Mae files in another fixed directory.
Note that the installers (where possible) will include a copy of a recent Java Virtual Machine (JVM) from InstallAnywhere(TM) to make running Cvt2Mae on your computer more robust. This is used locally and only affects the running of Cvt2Mae. It will not affect any other Java applications on your computer. In the case of Mac OS, if you have an older version of the MRJ JVM, it will ask you if you want to upgrade to the newer version (MRJ-2.4.5) - however you do not have to unless you want to.
The Cvt2Mae appendix describes the details of using the Cvt2Mae converter. Several PDF tutorials are also available here.
1.3 Downloading just the Cvt2Mae.jar file after initial install
If you have previously done an installation. you may avoid a complete
re-installation download by getting just the latest Java Cvt2Mae.jar file. You should replace the
old version of this file on your system with the one you are
downloading. This will work if the new Cvt2Mae.jar file does not
depend on any new entries in the configuration files (which generally
the case - try it and see what happens).

limit stacksize unlimited
In addition, we have set the default stack size that Cvt2Mae uses
to 256Mbytes. If your computer has less physical memory, it will
page. You may also increase this number as well if you have more
memory and want to use it. The solution is to edit the Cvt2Mae.lax
file found where you installed Cvt2Mae. Change the two instances of
memory allocation from 256000000 to a smaller number that is less than
your actual memory size.
and choose the appropriate patch set for the version of Solaris (2.6,
7, or 8) that you are running. Do not choose any of the x86 versions
unless you are running Solaris x86. Click on either the Download HTTP
option or Download FTP option, and click the "GO" button to download the
2.2 The Cvt2Mae Error Log Files
Each time you run Cvt2Mae, it creates or overides the previous error
log files called StdOutLog.log and StdErrorLog.log in the
installation-directory. If you are experiencing major problems,
these files are useful to us in helping figure out what is
wrong. Otherwise, just ignore them.
2.3 Sun Solaris (or other Unix system) Memory Problems
We have on occasion seen the following types of memory errors. This
discusses how to handle them.
Cvt2Mae Stack size Memory Error on Sun Solaris
Running Cvt2Mae on a Solaris (or other Unix system) may produce an error similar to:
Stack size of 97664 Kb exceeds current limit of 8192 Kb.
(Stack sizes are rounded up to a multiple of the system page size.)
See limit(1) to increase the stack size limit.
If the Sun (under Solaris) is slow in loading Cvt2Mae or has memory
errors (shown above) one should first see what the memory limits are
set to on your machine using the "limit" command. If they are too
small they should be increased or set to "unlimited" (see in 2.4 above
Cvt2Mae LAX file
If the problems persist, one might have to edit the Cvt2Mae.lax
file found in the Cvt2Mae directory (see example below). The default
memory settings in the Cvt2Mae.lax file (found in the installation
directory) should be no larger than the total memory of the machine or
paging problems will occur. For instance, if you have 192Mb of memory
in your Sun, edit the
"lax.nl.java.option.java.heap.size.max" options to be under
192Mb. You can use any text editor to do this. More memory may be
needed to be installed on your Sun to run Cvt2Mae with very large
The Lax file is a startup file generated by InstallAnywhere when we packaged Cvt2Mae. It is used when Cvt2Mae starts up on your computer. We currently set the memory limits to 256Mbytes. If you have more memory, you can edit the Lax file to have it use more memory.
