I'm here to help ensure you're able to open QuickBooks Desktop on the new compute, Todd42.
You can start by reviewing the system requirements needed to run the program. I've added these links below to check the operating system, hardware, software, and other requirements for the version of your QuickBooks:
If you already have all the requirements, you need to make sure QuickBooks Desktop is also updated to its latest release.
After updating QuickBooks, restart your computer. Then, open QuickBooks and enter all the important information.
If you're still unable to enter anything, you need to perform the clean install.
Stay in touch with me if you need more help with QuickBooks. I'll be right here to help you.
