Serial number not sticking?
I enter the Aquarium version 3+ serial code, select the fish I want to see (16 in all), then run the screensaver and all works correctly for several days (sometimes a couple of weeks.
Then afer a week or two of running normally, the program reverts to a demo, and I have to re-enter the serial number and re-select the fish? This happens regularly!
I am running Windows 10 home edition with an AMD Radion high definition graphics card and 32 gig of ram on dual 24 inch monitors with 3 hard drives, two internal (1 ter and 2 ter) and one external 2 ter.:(

When did you buy the Key Code? Send me a private message with your info, and I'll see what I can find out.

There doesn't seem to be any resolution on this. I just wanted to add that I have the same problem. Every now and then, the program forgets that it's registered and returns to the defaults. I have to re-enter the registration code and recreate the fish selection. Running Windows 10 Home (1803).

I had that problem too, My serial number would only last about a week, and I had to keep re-entering it. It has been a long time since I fixed the problem, but I think it was related to installing the screen saver with administrator privileges.

Uninstall the screen saver. Re-boot your computer (not sure if necessary, but why not). Right click on the MarineAquarium3.exe install file and select 'Run as administrator'. After installation enter your serial number (if it is not already registered).

Thanks for the info, Scandy.

Scandy: Thanks for the reply. I've reinstalled as you suggested. Since the problem is sporadic and unpredictable, there's no way to tell whether the fix worked unless the serial number is lost again. I'll post back if it fails again, and if my increasingly porous memory allows, if it doesn't fail over a sufficiently long period.

Uninstalling and reinstalling with administrator privileges has not worked for me.

I am also running into the same issue....the serial number is not sticking...I have to enter it everytime it kicks in!!

The only thing that is new for me is that I upgraded to Windows 10.
I installed my goldfish screensaver as well...that had the same issue...

On a side note, I noticed I have been owner of this screen saver for over 16 years now! :)

Same problem
Hello, I bought it today, and I have the same problem, even if I install it in administrator mode... :(

Jim Sachs 12-21-2018 11:31 AM

Are you absolutely positive you entered the Key Code correctly? Did you enter it manually, or cut and paste it from the confirmation email?

s.winterstein 01-11-2019 07:03 AM

Same issue here: the keycode would not stick after I installed the new 3.3 version.

Keycode is correct (from my user account a Prolific Publishing) and pasted.

Jim Sachs 01-11-2019 11:03 PM

Make sure that an extra [space] didn't get picked up with the cut-and-paste.

This symptom (running normally a few times, then requiring the Key Code again) is what happens with a bad Key Code. The theory being that if someone uses a bootleg Key Generator, it will seem to work for a random number of tries, then start requiring a Key again.

The only other thing I can think of is that Microsoft might have changed something in the Registry format so that the Aquarium is looking in the wrong place. The last few updates to Win 10 have broken several of the programs on my older computer.

Fix ... for me. (Windows 10)
Concerning the Re-entry of key issues. Today I purchased v3.3 for windows and installed it as admin with antivirus turned off and rebooted. I also had the same issues. Upon a quick look at the registry, it appears that the regcode is copied to 3 locations, but one of the locations is not updating the regcode. This is a design flaw in the program and not a Windows thing. I'm running Windows 10 Pro 64-bit with all the updates - today is 1/12/2019.

Regedit keys go here:

HKEY_CURRENT_USER\Software\SereneScreen\MarineAqua rium3

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\SereneScre en\MarineAquarium3


...but the regcode is not getting written to the HLM (HKEY_LOCAL_MACHINE) section.

I copied it there from HCU and all is working fine now.

Hope this gets fixed on v3.4


-Galo :TU:

feldon34 01-13-2019 12:09 PM

The Aquarium is supposed to write to the HKEY_LOCAL_MACHINE\SOFTWARE\SereneScren\MarineAqua rium3 key and then Windows automagically stores it in the WOW6432Node and reads from that when talking to 32-bit applications.

If the Aquarium is not using the correct C++ programming, this could explain the problem.

The folks who are having problems -- are you on 32-bit or 64-bit version of Windows 10?

Ralph 01-14-2019 07:44 AM

Interesting on my Widows 7 machine there is nothing at
HKEY_LOCAL_MACHINE\SOFTWARE\SereneScren\MarineAqua rium3 (Typos noted) but instead find mine at

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SereneScre en\MarineAquarium3 but the RegCode just shows 0000 00 . The data between the 00 and "." is hidden.:D

Vinz Clortho 01-18-2019 10:27 AM

I have entered the data into the relevant key and I will let you know if it gives me any further problems. It is working so far. Thanks Tiki.

StuDisney 01-19-2019 08:20 PM

are any of you who are having this probum runing Cclener , maybe it is removing the key code

Jav400 01-21-2019 06:44 AM

I use C Cleaner all the time and it doesn't bother mine, so I would guess that would be a special case.

GLS432 02-20-2019 07:47 PM

Since the reinstall on 10/28, the serial number has stuck, even through the update from 1803 to 1809. This is a 64-bit Windows 10 installation.

Jim Sachs 02-22-2019 10:35 AM

Glad to hear it. :)
