Why %TOPDFBUTTON% macro doesn't become a button?

I've installed ToPDF plugin without any problems though Extensions section in config and changed topdf.php as stated in documentation, but %TOPDFBUTTON% is shown as plain text.

The server is Apache 2.2 + PHP 5 mod on Win XP.

Can the problem be in format of the mentioned path in topdf.php? I've used both forward and backward slashes but it didn't help. Path is initially "c:\program files\Foswiki\Foswiki\lib".

Also when trying to find out what's wrong I've noticed that ToPDF plugin isn't marked as installed in the list of extensions. Re-installing haven't fixed it. Is it pointing to another problem?

Did you remember to check the "enable plugin" checkbox in the bin/configure interface? What shows in the System/InstalledPlugins page? Does it show as enabled, and are any error messages reported?

Yes, George, I've enabled plugin through configure and installation finished without errors.

It is shown as enabled:

But in the Extensions/Find more extensions it is not marked as installed:

That's why I am a bit confused regarding what can be the reason for it

New details: ToPDFPlugin really reports erros in System/Installed Plugins - sorry that I've misunderstood what you've asked at once.

Here is how it fails:

sorry, this plugin seems to have been deprecated by its author, advising everyone to use one of the others.
