4 users found this article helpful
In some cases, Quattro Pro's default installation may become corrupt or damaged preventing the application from launching or working properly.
 
You may also see unexpected symbols at the beginning of cells when a "Currency" numeric format is selected.
 
This document will restore factory defaults through a two-part process of renaming Quattro Pro's registry entries and configuration files.
 
To restore the product to its factory defaults, follow the instructions listed below:
 
This article involves editing the Windows registry. When working with the registry, a backup MUST be completed. Here's how:
  1. In the Windows Search type "Regedit" or press WIN+R and type "Regedit" 
  2. Locate Computer by scrolling to the very top of the left side of the registry  
  3. Once found, select the registry key in the left pane so that it becomes highlighted. 
  4. From the Registry Editor menu, choose File and then Export. You can also right-click or tap-and-hold the key and then choose Export.
      
  5. In the new window that appears, double-check that the Export range selected is set to ALL 
  6. Once you're sure you'll be backing up what you expected, choose a location to save the registry backup file to. 
  7.   (We usually recommend choosing the Desktop or the Documents folder) 
  8. In the File name text field, you may want to name it something like Complete Registry Backup / Reg_Backup 
  9. Select Save 
  10. Once complete, a new file with the REG file extension will be created in the location you selected 

 

 
 
First, make sure that all WordPerfect Office programs are closed. This is very important. If any of them are open, the reset process will not work as expected.
