If the extraction of the downloaded ZIP file is stopped with security warning messages
(for Microsoft® Windows®)

On the recent versions of Microsoft® Windows®, the extraction of the ZIP file downloaded from the VCSSL official website (for example, the VCSSL-runtime-einvironment, or VCSSL programs distributed on the code archive, and so on) may stop with security warning messages (e.g. " ... is potentially harmful").

It may be caused by that the security feature of the OS detects batch (.bat) files contained in this ZIP file as "potentially harmful", because generary this type (.bat) of files can execute OS commands.

In that case, to extract, right-click the ZIP file and choose "Properties" from the menu, and enable "Unblock" checkbox at the right-bottom (in the line of "Security") of the properties-window. Then try extracting the ZIP file again.

If the error message about non-availability of "java" command is output
(for Linux®, etc.)

On the Linux® or other OSes, to execute the downloaded VCSSL programs, it is necessary to execute "VCSSL.jar" by using java command on the command-line terminal as follows:

java -jar VCSSL.jar

As the result of the execution of the above command, if the error message about non-availability of "java" command will be output, it requires Java® runtime environment (JRE).

If you can use "apt " command on your command-line terminal, you might install JRE by using apt. Firstly, search available packages:

apt search jre
(or "apt-get" instead of "apt")

and then install appropriate one, for example:

sudo apt install default-jre
(or "apt-get" instead of "apt")

or

sudo apt install openjdk-?-jre
(?: version numbers)

Please note that VCSSL.jar will not work on JRE with the name ends with "-headles".

If the error message about non-availability of enough memory is output
(for Microsoft® Windows®)

The default memory amount allocated for executions of VCSSL programs is limited, so it may not sufficient to take heavy operations (for example, opening heavy files, rendering large images, and so on).

On the Microsoft® windows® if the error message about non-availability of enough memory is output, please execute the batch file "SetMemorySize.bat" by double-clicking to set the allocation size of the memory to the sufficient size.

If the error message about non-availability of enough memory is output
(for Linux®, etc.)

The default memory amount allocated for executions of VCSSL programs is limited, so it may not sufficient to take heavy operations (for example, opening heavy files, rendering large images, and so on).

On the Linux® or other OSes, if the error message about non-availability of enough memory is output, please execute VCSSL.jar by "java" command with "-Xmx" option to specify the allocation size of the memory to the sufficient size:

java -xmx512m -jar VCSSL.jar       (for allocating 512MB)
java -xmx3g -jar VCSSL.jar         (for allocating 3GB)
