If you are having trouble adding a user-defined assay to xChek software and are using Microsoft Windows Vista or Microsoft Windows 7, please read and follow the directions below.

 

Adding user-defined assays for Microsoft Windows® Vista®/Windows® 7 users

Error: Microsoft Windows Vista and Windows 7—Cannot Save Changes to CWindowsxChek.ini

Cause: On the Microsoft Windows Vista and Windows 7 operating systems, the xChek.ini file is a protected file, which means that the file cannot be changed

Resolution: Change the security setting to allow changes to the xChek.ini file.

Note: You must restart your computer at the end of this procedure.

  1. Open My Computer, and then find the xChek.ini file, located at C:\WINDOWS\xChek.ini.
  2. Right-click the xchek.ini file name, and then select Properties.
  3. Click the Security tab.
  4. Click Edit.
  5. For each user name, select all the boxes in the Allow column (so that each box has a check).
  6. Click OK. A message warns you about changing the security settings.
  7. Click OK to close the warning message.
  8. Shut down all applications, and then restart your computer.

You should now be able to edit and save changes to the xchek.ini file.
