Quickbooks 2005 decided to quit running on my Windows XP SP2 a few weeks ago. Nothing had changed on my machine or the server, and none of the other client machines were experiencing this problem.
I started by trying to perform a Quickbooks repair, but the problem persisted. Uninstalling and reinstalling Quickbooks didn’t change anything either. No related errors were appearing in the Windows XP Event Viewer, and a search of the Quickbooks and Microsoft knowledge bases didn’t turn up any solutions or suggestions.
I probably completed the uninstall/reinstall process half a dozen times before finally hitting on the correct steps to fix this problem. If you choose to try to use these suggestions, please backup your machine (or at least the registry) before doing so.
1) Go into Control Panel – Add/Remove Programs and uninstall Quickbooks 2005
2) Run MyUninstaller, and verify it doesn’t think Quickbooks is still installed. If it does, use the uninstall function within MyUninstaller to remove QB.
3) Download the Macromedia Flash Player Uninstaller, and uninstall your current version of Flash. I had version 9 installed, and Quickbooks installation fails if it cannot install Flash version 7. After the uninstallation completes, reboot the machine.
4) Rename the C:\Program Files\Intuit\Quickbooks 2005 folder.
5) Search the registry for all instances of Quickbooks, and remove them. Delete all references to C:\Program Files\Intuit\Quickbooks 2005, or whichever directory you installed Quickbooks into. Backup the registry before doing this, in case your changes affect other programs.
6) Rename the C:\Program Files\Common Files\Intuit directory. If you run other Intuit software, this may impact those programs, so rename rather than delete.
7) Rename all the QB*.* files found in the C:\Windows\Prefetch directory. Reboot again.
8) Run the Quickbooks setup program and install with default settings, including Flash 7. Once your Quickbooks is again functional, you’ll be able to update to Flash 9.
9) Download all the Quickbooks updates and install them. You should now be able to login to the Company File without hanging the program.
