I do not like the way MS embeds programs into the OS. eg Internet Explorer and Windows Explorer(File Manager or whatever they are calling it now)
I do not like Windows Explorer
And I certainly do not recommend messing with Windows Explorer (messing with the file system)
What I recommend (and use) is XYPlorer.
It has Tabs, and tons of other great options)
And it is portable, so changes that you do within it, cannot hurt your Windows in any way.
There is a free version (XYPlorerFree 17.4) that you can get from -

@Developer,

I run xampp with Tomcat. After installing FileMarker.NET, xampp control panel reports:
10:08:35 PM [Tomcat] Checking for service (name="Tomcat7"): Service not installed
10:08:35 PM [Tomcat] Service Path: Service Not Installed
10:08:35 PM [Tomcat] Checking default ports...
10:08:35 PM [Tomcat] Portblocker Detected: FileMarkerService.exe
10:08:35 PM [Tomcat] Checking for App: c:\xampp\tomcat\bin\tomcat7.exe
10:08:35 PM [Tomcat] Portblocker Path: Unable to open process
10:08:35 PM [Tomcat] Portblocker Service Path: C:\Program Files (x86)\FileMarker.NET\FileMarkerService.exe
10:08:35 PM [Tomcat] Problem detected!
10:08:35 PM [Tomcat] Port 8080 in use by "C:\Program Files (x86)\FileMarker.NET\FileMarkerService.exe"!
10:08:35 PM [Tomcat] Tomcat WILL NOT start without the configured ports free!
10:08:35 PM [Tomcat] You need to uninstall/disable/reconfigure the blocking application
10:08:35 PM [Tomcat] or reconfigure Tomcat and the Control Panel to listen on a different port

I have too many other things depending on xampp using what it was originally configured for.

How do I change the port used by FileMarker.NET?

... and why does FileMarker.NET need to have any port access at all? Your program should be affecting Registry entries. What are you using port 8080 for?

Try selecting a ".bat" file or a ".cmd" file. They can be selected, and icons chosen, but the Apply results in an error:
The files with ".bat" extension can't be customized.
The files with ".cmd" extension can't be customized.
The error occurs even if run as an Administrator. There is no indication that this is a system limitation, or a problem in FileMarket.NET.

If they cannot be customized, why allow user to select them? Let the user know as soon as possible that the remaining steps are futile.

What is odd is that the icon choices change for ".bat" and ".cmd" files compared to a ".txt" file, so the program knows to present different choices to the user. That makes me think it is a bug in the program.

Anyone have other ideas on this?

Why does everyone over think everything...of course it has to change the registry...how else will it change a file icon ?
Who cares what version it is...it's FREE.
Everybody with they're over kill anti virus software...should not have to disable it to install anything...
Read the 'read me' file...stop whining about not being able in install anything.
Software Informer comes up all the time...you DO NOT have to install it.
This is a really decent program.

Not sure if download is actually activated or not. How can I tell to be certain?

Creating a restore point is required; It penetrates deep in the operating system!!! Much more than other similar programs. This has been a concern for several machines.

Can somebody tell me how I would install GOTD software?
I extract the zip and get the install exe.
Running the install exe, I get a window "Successfully activated" while in fact no installation has been made - problem with antivirus possibly?
BUT in that window "Successfully activated", there are two buttons "Install Software Informer" and "Close", and I do NOT want to install "Software Informer" which is a spy program, so I click on button "Close", and no install is made here either.

So does GOTD makes the installation of "Software Informer" mandatory, in order to leave that "Successfully activated" window, for then the installation process to begin finally, or is it all an antivirus problem, and here with this window, the installation process should already have been taken place?

(I have this problem with GOTD ONLY, so for month, I have never successfully installed anything from them anymore; I have asked this question on another offer yet, without having had any answer - I should probably resign from even looking out for "giveaways" here which never work for me?)

Thank you for an answer, and no, I'm NOT willing to click on button "Install Software Informer" just to try.

If you get a small pop-up while installing, disable your virus protection for 10 minutes. Installed perfectly on Win 7 Home Pro 64 bit. Thank you, GOTD.

Their download versioned 1.0.1.0 is digitally signed and the signing date is 01 November 2013 17:50:38 which is quite a long time ago so there has certainly been no development work done since ALL the previous giveaways of this despite problems being reported during those giveaways. Also first public preview of windows 10 was in October 2014 so there has been no dev work on this for the entire life of Windows 10 in all its guises!
