Although IGMAS+ has been tested by many users around the world, there could still be a number of bugs and issues. In the changelog of every release we highlight the issues that have been solved. More information can be found in the release posts.
Feel free to provide us some feedback.
Below we list some known issues during installation and running IGMAS+, together with workarounds.
The jar installer does not start
On Windows, if you double-click on the IGMAS-install.jar
file and the installer does not start, a common root cause is that another program has stolen the .jar
association.
The workaround is to reinstall the Java Runtime Environment or fix the Windows Registry manually. You can also easily fix the problem with Jarfix.

Java 3D Not Installed
On Windows, the following error:
can have different reasons behind:
JRE version
This type of message is related to the fact that the version of JRE that has been installed is wrong. For instance, one could have installed the x86 version of JRE (for a 32-Bit system), but not the x64 (required for a 64-Bit OS), or the version is not 8.
JogAmp libraries missing
This message can be related to the fact that you are installing IGMAS+ as a Standard User and not as an Administrator. In some cases Windows can block creation of temporary files created during installation (namely the JogAmp library and its component GlueGen).
If you are not able to install IGMAS+ as Administrator, a workaround for it on 64-Bit Windows would be:
- Install IGMAS+ as a Standard User.
The default folder isC:\Users\<your username>\IGMAS+
- Create a folder named
natives
underIGMAS+\bin
- Load
jogamp-all-platforms.7z
file from the JogAmp archive - Unpack the
jogamp-all-platforms.7z
archive (e.g. with 7-Zip) - Put the contents of folder
jogamp-all-platforms
toIGMAS+\bin\natives
- Move the folder
windows-amd64
from\IGMAS+\bin\natives\lib
to\IGMAS+\bin\natives
.
Too small font size
On Windows, when using displays with high resolution and system scaling, the fonts in IGMAS+ can still be too small:
Here is a workaround in case of too small fonts on Windows 10/11:
-
Find out the path for the java binary IGMAS+ is using
- Start IGMAS+
- Open Help -> About
- Check the path in Runtime:
In this case:
C:\Program Files\Amazon Corretto\jdk1.8.0_342\jre\bin
-
Open File Explorer and navigate to this
jre\bin
folder- Right click on file
java.exe
- Click Properties
- Go to Compatibility tab
- Click Change high DPI settings
- Mark checkbox Override high DPI scaling behavior
- Select System from the dropdown Scaling performed by
- Click OK
- Click Apply
- Right click on file
As a result, fonts are scaled:
