Just tried 7.31 installation (upgrading from working 6.51).
I can observe the following:
- jCore (6.80)
- JFx (6.50)
- opening Tools/path (it shows correctly "C:\Program Files\Java\jdk1.8.0_201\bin\javac.exe") and clicking OK after no modification at all an error message shows ("Input string format not valid"); same when filling the Additonal Lib field)
- Tool/IDE options let me change language and/or theme, but exiting the IDE and loading it again shows the default selections (different from the ones I had in B4J 6.51)
Update: disinstalled 7.31, installed again from the admin account. Same problems. When 7.31 is disinstalled version 6.51 starts with its correct and personalized settings
