Can you check the Java installed or Java env settings?  and if you feel uncertain about the install Prerequisites. please click "Help -> User Guider" to open the GUI Guider doc and check them.

HI thanks for responding, I'm just seeing this now.

Not real sure how to check on my java installation, but I did some peeking around and found that some install must have installed the Java SE development Kit 8? (see attached pics below)

I never purposefully installed it and don't know how to use it. I'm running Windows 10 (see pics below for current version).. And interestingly enough if I type in the command "java -version" and  I get the same error.(See Pics)

I'm lost for a solution at this point? Do I uninstall and reinstall a new version of the JAVA SE? does an environment variable need to set to point the the installation? do you know of hand what quiGuider supports?

Any direction that you could send me too, would be greatly appreciated.

Hi skruglewicz, 

You can download JRE from https://www.java.com/en/download/manual.jsp and install it on your PC, then follow below steps to configure environment variable. 

a. Open Control Panel and search env.
b. Choose "Edit the system environment variables"
c. Click the "Environment Variables…" button.
d. Under the System Variables section (the bottom half), select "Path" variable and click "Edit" to open the Edit UI. 
e. Click New and type in the java path. For example, C:\Program Files (x86)\Common Files\Oracle\Java\javapath.
f. Click OK to save your change.

After above changes, please try again.

from your pics, I guess that your host pc missed JRE(Java Runtime Environment), only installed JDK(Java Development Kit).  

You can uninstall this JDK, and reinstall the full Java environment. The appropriate version can be obtained from GUI Guider doc.

Thank you LiubinGong, 

That was exactly it. The JRE was missing and I only had the JDK installed. I should have read the GuiGuider User Guide... I am no longer getting the following error: 

Error: opening registry key 'Software\Avast\Java Runtime Environment' Error: could not find java.ll Error: Could not find Java SE Runtime Environment.

What I did was

1) uninstall the 2 versions of the JDK as I wanted a fresh install.

2) downloaded a new JRE from Oracle from this page Java SE Runtime Environment 8 - Downloads - Oracle

I download the follow version.

Windows x64

80.7 MB

jre-8u291-windows-x64.exe

And installed it. The install only installs the JRE because I don't need the JDK at the moment.

3) I then added path "C:\Program Files\Java\jre1.8.0_291\bin" to the PATH System environment Variable.

4) to test the installation from a command I ran the following java command , and it displayed the current version.

Thanks
