Question:
The end user encounters the situation that he can't install the Socket Filter Agent(SFA). 

He installed/uninstalled the SFA a few times on the box. On the situation, the below problem occurs. 

1. He tried to install the SFA but the following error occurred. (Seee the log.txt) The "control panel" > "Programs and Features" did not have the SFA, but the service.msc has the SFA service. 

2018/10/10 17:44:30 DriverCreate: Can not create service, ERROR: 1073. Returning Failed status. 

2. Opened the command prompt and run the command to remove the SFA service, and deleted the SFA service from there. 
(When the command was run, the SFA service appears there. But after a few minutes, the SFA service disappear from there) 
As the program list, services.msc don't have the SFA, it looks like being the situation as well as the situation before installing the SFA. 

3. Try to install the SFA on the box. But the same error occurred and failed to install the SFA. 

4. Rebooted the OS. 

5. Tried to install the SFA but it failed because of the same error, too.
Environment:

Answer:
1. Download the Microsoft ‘Program Install and Uninstall’ utility: 
https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed 
2. Launch the utility 
3. ‘Are you having problems installing or uninstalling a program?’ 
    • Choose ‘Uninstalling’ 
4. Choose ‘Not Listed’ 
5. Use Product Code ‘{5A2A2643-2BD6-4D09-9B03-E08098887B06}’ 
6. Result should say fixed and have a green check-mark. (Close this dialog) 
7. Delete additional registry keys by running reg file that I have uploaded to the support FTP for this case: ‘cleanup_winsfa.reg’ 
8. Reboot the PC (IMPORTANT!) 
9. Log back in as ‘Administrator’ 
10. Delete the ‘C:\Program Files (x86)\CATech’ folder and all contents. 
11. Now, you will be able to install the new 3.x version successfully.
