Cannot reinstall Password Manager

Hi @dctrivandian, I completely understand your concern and feel sorry for the inconvenience this has caused.
Since this is a different question, we've created a new post for your issue. I understand that you already tried to reinstall the program and encountered an error message “You already have Password Manager installed.” We are sorry for the inconvenience this has caused you. Let me help you with this. 

This can happen if the desktop application is not running properly or if you don't have the desktop application installed. 

To backup and delete the Password Manager files on registry, please do the following: 

1. Click on Start button or Orb button at the lower left of your screen and then select Run. 
2. If you are not able to see Run, click on Start button All Programs Accessories Run. The Run command should open. 
3. Type “regedit”, click Ok. 
4. Click on File. 
5. Click on Export. Export Registry File window will appear. 
6. Provide a filename that you want for the backup file, select your Desktop as the location for easy access to the file then choose Save. 
7. Go back to Registry Window and then click on HKEY_LOCAL_MACHINE Software Trend Micro TMIDS. 
8. Right click on the "TMIDS" folder and click on "Delete". 

Here is the next step: 

1. On the Registry Editor, click on HKEY_CURRENT_USER Software TMDP. 
2. Right click on "TMDP" folder and click on "Delete". 
3. Close the Registry Editor. 

The last step is to delete the folder of Password Manager in the Local Disc (C:). 

1. On your keyboard, press the Windows Key + E. This will open the Windows Explorer. 
2. Go to this location

   Note: You might have to unhide your folder first. Here are the steps on how to unhide it:
   a. Open Folder Options by clicking the Start button, clicking Control Panel, clicking Appearance and Personalization, and then clicking File Explorer Options.
   b. Click the View tab.
   c. Under Advanced settings, Untick the Hide empty drives, Hide extensions for known file types, Hide folder merge conflicts and Hide protected operating system files.
