Also, keep in mind that when you upgrade your version of wine and use the same WINEPREFIX to run your program, wine will update your WINEPREFIX, and you cannot simply downgrade wine to run from the same WINEPREFIX. You will need to create a new wineprefix using the older wine and and reinstall your program. If your program runs correctly in a current version of wine but are unsure whether a new version of wine will adversely affect a program that is important to you, you can copy your WINEPREFIX and try out your program from your new WINEPREFIX. If everything is fine, you can delete the old one.
