At the suggestion of X1 tech support, I did a clean uninstall of X1 and reinstalled it. That solved the problem for me. Here are the instructions I was given, but you should confirm that this will work for you by contacting tech support. You will need your license ID and password to do the new installation. As always, be sure to set a restore point before doing anything that involves your computer's registry.
PREREQUISITE:
If you can launch the X1 interface go to Menu > License and Deactivate your current license activation.
- UNINSTALL
1. Access Control Panel > Programs & Features.
2. Uninstall X1 Search. When prompted, opt NOT to save your X1 settings.
3. Check the following locations for remaining X1 Search files, and delete them:
- C:\Users\<username>\AppData\Local\X1 Search - this is the default location of the X1 Search data directory.
- C:\Program Files\X1 Search - this is the install location of the X1 program files.
- C:\Program Files (x86)\X1 Search - this is the install location of the X1 program files on a 64-bit operating system, running a 32-bit version of Outlook.
NOTE: You may find an X1 Search directory under C:\ProgramData\. You do NOT need to delete this directory.
4. Click Start > Run > Regedit or click your Windows Logo Key + R to launch regedit.exe and delete the X1 Search registry keys found in any of the following locations:
- HKEY_CURRENT_USER\Software\X1 Search
- HKEY_CURRENT_USER\Software\Wow6432Node\X1 Search
- HKEY_LOCAL_MACHINE\Software\X1 Search
- HKEY_LOCAL_MACHINE\Software\Wow6432Node\X1 Search
- FRESH INSTALL
1. Perform a fresh install of X1 Search 8 by launching the X1Searchsetup.exe found here:
