You may want to look on down this page for some other options, but if you are getting Error 41, that is a sign that one or more files is either missing or corrupted. The FIXME.bat can usually help- make sure you are OUT of UFT when using it, though. And ... note that FiXME.bat only restores the default configuration files for UFT and will not correct errors in the data files themselves. Since you've tried this, however, you may need to rebuild your project files. To do this, create a duplicate project and save it as something elese (to not override your original project by using the same name). When the project has been fixed, you can then delete the original project. If this does not work, you may have to try reinstalling the program files only (not a full installation) using the "Custom" option. You can then select just the files that need to be reinstalled.
