Windows: Logger Pro hangs/crashes when I start it or takes several minutes to come up.

While attempting to start Logger Pro, you may see a window that says: "A problem has caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." or after clicking on the icon Logger Pro may just not show up at all, or Logger Pro may take several minutes to show up.

0) Reboot the computer and try again.

1) Reinstall Logger Pro. Also make sure that you are running a version of Logger Pro that supports your OS. For Windows XP, any version of Logger Pro 3 will work. For Windows Vista you need to be running Logger Pro version 3.7 or higher, for Windows 7, you need to be running 3.8 or higher, and for Windows 8 you need to be running 3.8.6 or higher. If you are running an old version of Logger Pro on new operating systems, that will cause this problem. Updated versions of Logger Pro can be downloaded here:

2) The next most common cause of this problem is that there is something wrong with Quicktime. Uninstall Quicktime from the Add/Remove Programs in the Windows Control Panel, and then reinstall it from:
http://www.apple.com/quicktime/download/
If you can't get Quicktime to uninstall, (for instance, you get error messages during the uninstall that you can't get past,) that is a good sign that you've found the problem. We aren't experts at Quicktime installation problems, but we can disable Quicktime so that Logger Pro will at least launch, (although Logger Pro won't play/analyze videos.) Be advised that we've talked to some people who have eventually had to reinstall Windows so they can get a working QuickTime install.

3) This also can be caused by interactions with LabView libraries. LabView isn't required for any part of Logger Pro, but LabView will work with our hardware and so we share some libraries with LabView if it in installed. However, uninstalling and reinstalling LabView is a lot of work to do correctly, so don't try that until we know that that is causing it: see step 4.

4) To figure out for sure what is causing the problem, download process monitor:

and run it, (and press OK: the default filters are fine.)
Then start Logger Pro and wait for Windows to tell you that it has crashed or for Logger Pro to eventually show up.
Save the file in process monitor and e-mail it us.
