Hi guys. When I run java -jar gui/target/shaded.jar per the instructions in the git repository ([build.md](http://build.md)) I get an error popup: ‘Couldn’t generate key’ Is this related to running in a non-standard location or have a ‘screwed the pooch’ in my build someplace? It seems to run fine after I dismiss the error box. ---

Have you followed all the steps (security files,…) seems the jdk crypto restrictions are not unlocked in your setup. ---

Yes, I followed the build instruction to the letter. OS is Windows 7 Home Premium with all updates (except IE11). ---

Doesn’t happen when I install from the newly-built executable. So this is just an artifact of running the java file. Probably can’t find a needed path or something. ---

Then the jdk setup is not done correctly. if run rom exe u use the packeaged jdk, if run the jar file u use the system jdk. maybe u have different jdks installed and JAVA\_HOME points to a wrong one? ---

Only one JDK here, it’s a brand new install of Windows 7 as of last week. But I have a different version, 1.8.0\_101 not 1.8.0\_92 ---

type java -version into the console to see which version is used and chekc if the setup was applied there, or change JAVA\_HOME to the newer versin (and apply the setup form the [build.md](http://build.md) there). JAVA\_HOME is set in system vars on windows. ---

java -version reports what I said: 1.8.0\_101 I know about JAVA\_HOME and already set it when I installed Java.
