AVG PC Tuneup doesn't work properly after installation

Twice I installed the AVG PC Tuneup.
Both times I encountered the same problem. 
After installation the program starts one-click maintenance and stops halfway at the Browser cleaning. The folowing messages appears:
-one click.exe failed and 
-integrator.exe failed

 When I deinstalled the program I got the message:
the registration of a module can't be cancelled:
Module DseShExt-x64
Action: 0
Failiure: 00000002 (2)
The system can't find the requested folder.

Wahat might cause this problem?

They've been monkeying with this website again. I'll try the link again:

Marvin, There's been no monkeying with any website. You've missed out the s in https (https://support.avg.com/answers?id=9

Browser cleaning issue sounds familiar: <<< dead link removed >>>
You could use something more dependable like CCleaner or SlimCleaner.

Marvin, Actually it'll work without the s but it should be products?id instead of products&id in your original link.
