Try shutting down the QBW32.exe process to resolve the QuickBooks Won't Open issue. To do so, first right-click on the Windows taskbar and select Start Task Manager. Select the Process tab as well, and then click the Image Name header. This will alphabetize the processes. Then you must locate and choose EXE. To end the QBW32.exe process, select End Process. Restarting your computer is also an option. You may quickly restore any prior modifications and save any updates that have not been saved by doing so.
