Hello,
Had same problem with older Windows. Use an older JRE - 8u172 should work found here → Java SE Runtime Environment 8 Downloads. Be certain to use the correct version bitwise - Windows x86 if you are using LibreOffice 32-bit or Windows x64 for LibreOffice 64-bit (probable installed version). I prefer to use the exe
downloads.
Also, go through (at least glance through it) the LO documentation (and samples available) found here → Documentation/Publications. In addition to the Base documentation, toward the top are the Getting Started
guides. Read the one for Base (Chapter 8). Further down the page you will also find How-tos and Tutorials
.
SQL is an absolute must for working with databases. There are many good sites on the net for help in this regard. Here is just one → SQL Tutorial.
Avoid using (or even thinking about it) macros. To go this route requires knowledge of Base first, then a great investment of time & effort on your part. Most of what you will need to do in Base can be accomplished without macros.
When you have questions, first search through this site for possible answer. If still a problem ask your question here & be specific with what you are dealing with. Most often, specifying what you are actually trying to accomplish is better to state in addition to what problem you are having.
If this answers your question please tick the (upper left area of answer). It helps others to know there was an accepted answer.
