I am trying to install ANSYS on CentOS 7.5 in a Docker container. When I click Install Electromagnetic Suite, I get the attached error below "This application require a Java Run Time Environment (JRE) to run. Searching for one on your computer was not successful. Please use the command line switch -is:javahome to specify a valid JRE

To locate my version of java, I used update-alternatives --config java. The command returned the following:

There is 1 program that provides 'java'.

  Selection    Command

---

*+ 1           java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/jre/bin/java)

The install help command says that I should pass the directory containing bin/java as the argument.

So I ran ./install -is:javahome /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/jre/

But I get the same error message, where the installation can't find my java installation.

How can I successfully install ANSYS on CentOs?

Here are the error messages I get on the terminal when I click Install Electromagnetic Suite

/home/developer/Electronics_192_linx64/Linux/AnsysEM/disk1/setup.exe.IShield: line 158: bc: command not found
/home/developer/Electronics_192_linx64/Linux/AnsysEM/disk1/setup.exe.IShield: line 1375: [: : integer expression expected

 Well, it turns out the problem was the bc isn't installed in the base CentOS docker container. After installing bc (yum install -y bc), the installation moves forward.

Hi grybka,

Thanks for the update and resolution.

If you haven't already done so, I would recommend to just install the full RedHat LSB package (yum install redhat-lsb) as you might come across other issues in the future.

Thanks,

Win

Hi, 

I have the similar issue. I have installed java and redhat-lsb and used -is:javahome and -is:log. Here is my log output. Please help thanks.

what is the output of

cat /etc/*release

and 

env

[chenniu]

Thanks for the respond. It was CentOS8, I reinstalled on CentOS7 and it seems to work. 

[tsiriaks]

sounds good. Thanks for the update. Yes, CentOS/RH 8 is still not supported even by current ANSYS version (2020 R1)

looks like you have to install
