M. Aronson, I guess you had a previous version. I just updated mine to this new version and added the activation code from the Readme file. It seems to work file at it says registered to ...the email address I used in registration. Clicking on help says: Phototheca Pro is up and running. So works for me.

Gary, Double click to select and enable full screen mode. Mouse scroll wheel zooms up or down.
Win10.

The same response now, after 11 hours. When checking for updates, get "Phototheca server is not accessible at the moment. Please try again later".
BTW, my previous comment was published 11 hours ago, not 6 hours as appears now.
What happens with the servers of both Phototheca and GAOTD?

Just Me,
If you delete a photo in Phtottheca then does it still stay on the hard drive?

Oops, first para was a bit fragmeneted at the end. Read: 2) Does it use the adjustment and keyword data that is stored in the LR sidecar files (which can be shared by other programs, e.g., On1 PhotoRaw.)?

Neil,
Let me answer your questions
1) As it stated in their Wiki: https://lunarship.com/wiki/2019/02/09/where-are-photos-placed-after-import-does-phototheca-create-copies-or-move-imported-photos-how-to-get-photos-back-from-phototheca/
this software does not copy or move images into own store, so it just index files.

2) As they state in News section https://lunarship.com/news.html
this software has feature:
"• Read XMP sidecar files of RAW photos to get keywords and descriptions into Phototheca"

So basically, it's yes to both questions. This looks as quite intelligent software that does things in the right way.

Neil, Phototheca does not move or copy your photos it only catalogs them and you can decide where to catalog them, and change where this info is stored instantly it defaults to Pictures but can be wherever you want.
I have been testing on a folder of 18,000 photos for a little while (not purchased yet, but soon will) I also have used Luminar 3, but find it too slow to organize nearly 200,000 photos, but I do use Luminar to edit. (Have not used LR since ver. 4)
Oh yeah, Phototheca finds and lists all your duplicate photos and allows you to delete those from its catalog but does not delete them from your originals, I find this very useful.
Please try this free today, I think you will be very surprised.

Thanks Anthony, I'll give it a try then!

Robert,
I read some of the articles about Phototheca and in the "Related Article" about "What does 'No File mean?" it states this...

"Phototheca does not copy your files during import from hard drives, but remembers location of files only."

Which agrees with what you wrote. However, it then goes on to this....

"If you do import from removable drives, such as flash cards, memory cards, etc. – Phototheca will copy files on your disk and would not loose them. "

There is a lack of clarity there. Does the author mean "Phototheca will copy files on your disk [i.e. *physically* copy photos on (e.g. a USB-attached drive, memory card, etc) to your hard disk] and would not lose them"
OR
""Phototheca will copy FILE LOCATIONS of photos on removable drives onto your hard disk and would remember those locations."

I suspect it's the latter, but it could/should be made clearer.

Colin M, I have only used Phototheca on a folder, not on a memory card or USB drive so I can't answer that. (That is a great question)
“No file” means that file does not exist anymore at the location it was when Phototheca imported file. (Not physically imported)
Phototheca does not copy your files during import from hard drives but remembers the location of files only. So if you move files to somewhere else – Phototheca loses files and displays “no file” icon.

If you do import from removable drives, such as flash cards, memory cards, etc. – Phototheca will copy files on your disk and would not lose them. (I need to check this out.)
I am still testing so I'm sorry I can't be of more help, Robert.

TK, thanks for the tip. Finding "settings" is not intuitive!

TK, seriously you are using Vista? That is absurd. You are running a desparately risky system connected to the Internet.

Michael Schore, Seriously you think that? Fact is, my windows Vista is fully patched and up to date with the March 2019 monthly rollup and because it has less of the network facing services than say Windows 10 it is inherantly more secure by virtue of its smaller exposed and potentially vulnerable network surface and significantly less undesirable telemetary that is foisted upon users like with Windows 10.
Add to that I am behind a stealthed NAT router with strong AES encryption on my WIFI with no 3rd party access permitted and IPv6, which the security of is not yet mature, access disabled. My private and personal files are measurably more secure from external data leaks on my Vista SP2+ laptop than on my WIndows 10 Business 1809 edition laptop.
If you write before you know the facts you make a fool of yourself!

TK, How is your Vista fully patched? As of April 11, 2017, Windows Vista customers are no longer receiving new security updates, non-security hotfixes, free or paid assisted support options, or online technical content updates from Microsoft.

CN, I am not going to divulge everything as it could result in the patches I use no longer being so easily available.. but the clue I will give you is Windows Vista = Server 2008 before the cuttof date the patches for either platform were for all intents and purposes identical. BTW I think you will find that contracted support arrangements are still avaialble for Vista Business customers IF they are willing to pay for it, as would be the patches since they are still being developped just not openly distributed for vista for free.

Michael Schore, Why are you having a go at TK for using Vist?, I suppose you're system is bomb proof! Personally I detest the system and wouldn't use it, but if others such as TK find that it suits their needs then that's up to them. TK posts good comments and if you have read any of his comments you'll see that he knows what's he's about.

TK, So you're the other one besides me that loved Vista. Nice to meet ya! I agree on the ability to secure an older system. Not clear on if you were able to successfully run this and if you liked it.

Blackhat, I'd guestimate he's new to the site and too inexperienced to realise that provided basic network connection hardening is done it is almost never an operating system vulnerability that exposes an end user to malicious software but it is normally some ill considered behaviour of the end user that exposes the system and LAN to malware of most types. I too did not like Vista to start with but compared to Win 10 and 8.1 and 7 I prefer it now. I did not like how it tried to conceal the workings further than XP did... and after several iterations of hardware upgrades it ended up with 3TB of hard drives and 8Gig of RAM with patched kernel to use it all in 32bit mode in the laptop with literally thousands of giveaway of the day programs and it became a DLNA media server using servio... There will come a day when the motherboard dies seeing as it is an HP pavilion laptop and is renowned for overheating and cooking its GPU which for the most part it has... hence me now using RDP 99% of the time.

BTW the ffmpeg.exe is only used to generate the thumbnails for some of the video types found in folders.
So not really critical to the operation of the program. I did replace their ffmpeg.exe with a vista compatible 4.1 version I got from one of the Chinese video converter giveaways from the not too distant past and it worked just fine.

TK, since ffmpeg.exe is licensed under GPL V3, or the version 4.1 that runs under Vista is, this developer should be able to get the Vista and probably earlier compatible fork of ffmpeg from modam players developers at https://modamstudios.com/ I have sent them a message asking if they would disclose their git or other repository of their 4.1.git version of ffmpeg.exe and ffprobe.exe we shall see if they are GPL V3 compliant in making the source available or not.

Dima T., it's in Help - unlock and activate. Just add any email and a password.

Dima T., assuming you will want to recover a forgotten password in the future ( no idea if we will ever need to ) you paste the key from the readme.txt in the input box at the top since we did not purchase it we don't have to wait for the key to arrive as we have it in the readme.txt file. Then put in an email address you own access rights to in the email address box and put in a password of your choice, advisably NOT one you have used in any other important account like gmail of facebook or other email service... and submit the data and then restart the program as instructed.

john, hmmm had a cursory look on their website and cannot find a reason for this account... no obvious account login page... maybe it's just a way to gleen email addresses or keep track of the number of installs per license key... Or maybe it is used to recover an lost purchassed key? *shrugs* until the vendor discloses what it's required for all we can do is speculate and I've wasted enough time on that for this giveaway.
