Use LicenseCrawler To Recover Your Lost Software Serial Numbers

Ads by Google

Have you ever had a installation of something that you wanted to reinstall but you couldn’t? Have you ever lost a software serial number or key code? How about something that was pre-installed on your system – how do you reinstall that? I have had issues with all of these situations and I know a lot of other people that have had these issues as well.

What can you do to solve them? How can we grab the information we need from the registry? That’s right – all of that information is in there if you know where to look for it and here is a program that can do that for you automagically!

It is a neat little piece of freeware called LicenseCrawler.

Once you download this little gem you can use it to scan your machine for serials. The program is 100% free – make sure you do not pay for it! Some of the download links ask for money ““ don’t use them! Use the free links! The author wants the application to be free, so lets keep him happy!

After downloading the application you simply run it and it will return all the keys from your computer. When you first run the application you will see a screen that looks like this:


You have the option of searching your machine or another on your network by replacing localhost with another machine’s hostname or IP address that you have access to.

You will need a user name and password for the remote machine with access to the registry. I would leave the registry setting set at HKEY_LOCAL_MACHINE and simply hit that start button. The application will scour your machine and return a screen with all of your keys. Yes MUO readers it is that easy!


The software serial numbers seen above are not real and just used for illustrative purposes. The key that comes up for Internet Explorer is actually your Windows Product Registration. You can use this key to reinstall Windows. All your other keys can be used in reinstalling these applications on another machine or simply after a format. You have to manually write them down as there is no copy  and paste functionality – hey no big deal for a free application that works just as expected.

Without this application I would have got caught with having to re-buy programs or at the very least having to contact each software maker’s respective support line and begging for them to reissue another key. I HATE DOING THAT! Why should I have to?

Have you had success with another License retrieving application? There have been many of these applications over the years but this is the best one I have seen so far. It got ALL of the keys I needed. I have used something called The Magical Jelly Bean in the past but that is strictly for Microsoft Applications.

We would love to hear about your experiences with software serial numbers ““ either good or horror stories! Please share them with us in the comments!

Thanks for this! I just went through reinstall He** when my PC got the Virut virus and had to be wiped clean.

One note: I was able to highlight/copy/paste the list easily.



You might want to blank out your serial numbers in the screen shots.

As Karl clearly states in the article, the numbers shown are not real.

These are test serials from a virtual box I am not worried… Why are you scouring the internets for a serial for something? I can think of better places to look than here :)

Wow, this is great! Found a Battlefield 2 serial number that I thought was a goner and wanted to install it on a newer machine. Sweet!



This is kewl! Now, I can find my long lost serials of my fave softwares.

Belarc Advisor is another good program to get your hidden serial numbers. For MS Office, it even gives you both the S/N that you needed to install and the generated registration numbers. In addition, it gives much more information about your computers. And it’s free.

I used couple applications to retrieve serials
Belarc Advisor
Magic Jelly Bean
SIW (System Information for Windows by Gabriel Topala) portable



Hmmm… You know? I DID copy the entire results on a notepad. You know, It’s just matter of select the entire text with the cursor, press Control+C, and paste it wherever you want to.

Can someone else try this? Or am I the only one capable of doing this?



Well copy/past works fine, but why not use the save file option if you need the serialno after a reinstall?



People are thinking it’s a way of getting free keys. Free keys as an download the trial version of something, then use this software to search for a key. Is this possible? Has anyone tried this yet?



Dear sir/madam,

Pls I Want a siral number for coral draw 12
and photoshop 7




It found a few serials but didn’t find the most important one I was looking for, my Photoshop CS4 serial number. I don’t think there’s any way I can find it now

Hello Karl
This little utility works flawlessly

However, My window crashed and I had to load a new one on a new drive. I put the old one in as a secondary drive. Now I have all those missing serial numbers on the secondary.

I only have one computer and I do not want to buy all those programs again.

Thoughts? Ideas? Suggestions?

Karl Gechlik

The old drive does not boot? You can not boot to it and then run this?
