How can I tell if there is a newer version of Metron-U available?

You can check which version of Metron-U you currently have by starting up the program, and clicking on the "About" item in the top bar. This will bring up a panel giving some general information, including the "Version #" for your copy of Metron-U. Next, you can go to our Download page and on that page you will see the currently available version number. If the current version is higher than your version, then you might want to upgrade to get the latest improvements. If you version is 1.X then you may upgrade to the current Metron-U version 2.X for $99 using our Order Form. If you wish to just upgrade to the last series 1.X version for free, you may download it here.

If you want to read about the changes (to see if they are worth getting) we keep a list of all the changes here.

1. Download Metron-U from the website ( from our Download page ) This will result in a file called EponaU2.exe on your system ( note: if you still have an EponaU2.exe file from a previous download, you might want to delete it first, to avoid confusion).
   
   
2. Once you have EponaU2.exe, when you double-click it, it starts the installation process. When it asks where to install Metron-U, you should put it in the same place where you installed last time. By default, it suggests C:\EponaU -- so if you used the default last time, just use it again. This way, the new Metron-U will overwrite the old Metron-U, which is fine.
   
   
3. This "overwriting" will not delete any files you have added to the system. For example, if you have imported images and marked them up, etc. they will still be there after the upgrade.
   

Include your e-mail address and/or physical mailing address so we know who you are.

If you'd like to purchase by "bank transfer" or "bank wire" send an e-mail to us to get our banking info.

• $599 for Metron-U
• Version 1.X customers may upgrade for $99

How does "Free Mark-Up" work? I'm having trouble Moving and Deleting Items...

Here are the basics: Except for "Measure Curve Length" and "Measure Area", the other items work in the following way: For example, if you click on "Angle Measure", you'll see a prompt telling you to pick 3 points in the image, and a little diagram showing how those 3 points relate to the angle you will measure. As soon as you've picked 3 points on the image, the angle-measure will appear. Once the item is added to the image, you move it by pick-hold-down-and-drag with the mouse -- the trick is that you move these objects by their "control points" which are usually the endpoints. For the Angle-Measurer there are 3 control points -- you have to drag each one separately. One exception to this is the Circle-Radius-Measurer -- it can be dragged also by its center point. Note that each item you add is auto-assigned a name, but you can edit its name, as well as details of color, font, etc by using the selections in the center of the panel. If you're not sure which item you are editing, just pick a control point of the item you wish to edit -- this will select it as the "current note" and then you can edit its details.

The "Measure Curve Length" and "Measure Area" tools operate a little differently since they can be composed of any number of points: when you first create them, you'll see some extra buttons appear on the panel which allow you to switch between "Add Points", "Delete Points", or "Move Single Point". You'll see the shape of the cursor change when in Add or Delete mode, to remind you that you are in that mode. There is also a button (labeled "Other End") which reverses the sense of the curve you are picking so you can add points to the other end of the curve. If you are adding to or deleting from one of these objects, and you want to get back to picking and editing another object, switch the selector back to "Move Single Point" and then you can pick anything on the screen.

There is also a concept of the "current object under edit" -- whichever object you last pick has this status, and any text associated with it is displayed in the text window within the Free Mark-Up panel. Then, the current object can be deleted by clicking the button in the lower left-hand corner of the panel. So, to delete any object, just pick one of its control points (to make it the "current object") and then hit the delete button.

I already bought Metron-U -- How do I 'Unlock' it to get out of Trial Mode?

See our document on 'How to Register Metron-U'

I am installing Metron-U on a new computer. How do I move all of my images and data from the old copy of Metron-U to the new copy on the new computer?

1) First load Metron-U on the new computer either from a CD or by downloading it from the EponaTech web-site.

2) Start the new copy of Metron-U up once. It will initialize itself and will be in "Trial Mode" to begin with.

3) You can transfer all your data now (with instructions below) and then get an unlock code for the new copy of Metron-U. If you unlock first, the act of transferring the data will cause the system to revert to "trial mode".

4) Here is the quick summary of what you need to do (and then more details below if you need extra help getting this done). It is simply this:

You need to REPLACE all the folders located in C:/EponaU on the NEW computer with copies of the folders in C:/EponaU from the OLD computer.

5) Step by step how to do this:

5.1) On both Old and New computers, make sure you exit Metron-U before doing the following.

5.2) On the NEW computer, go to C:/EponaU and delete all the folders in there. They have names like "CutDate", "CutExam", "DataBase", etc. There are 10 or so of these folders. Make sure you are doing this on the NEW computer -- if you do this on your OLD computer, you will be deleting all of your images and data!!!

5.3) On your old computer, make copies of all the folders under C:/EponaU onto a CD, or onto a ZIP disk, or accross your network. This step is up to you, depending on what you have available to transfer the files from one computer to another.

5.4) At your NEW computer, move these copied folders into C:/EponaU.

5.5) Try starting Metron-U on the new computer. It will be in Trial Mode, but you will see that all your data is there.

5.6) There is one more IMPORTANT thing! If you used a read-only CD to transfer the files, then you have to tell Windows that these files should not be "Read Only" files. So go to C: and right-click on the EponaU folder (on the New computer) and on the pop-up list, choose "Properties". Near the bottom of the panel, it will say "Attributes" and you will see the "Read Only" may be indicated. Turn that OFF so they are NOT Read-Only, and click OK or Apply. You may be asked if you wish to apply that to all "sub-folders and files" and you should say Yes. This way it will make all folders under C:/EponaU able to be written and read. Metron-U needs to be able to write files to operate properly.

6) Now, get an unlock-code for the new Metron-U. To do this, start it up, then go to "Register" in the top-bar, choose "Unlock" and tell EponaTech the "Registration Number" that is shown there. From that, EponaTech will compute an Unlock Code which will work on that computer.

7) Note that this procedure left everything on your old computer also. If you don't want to use that computer anymore, you could un-install Metron-U from it now. Just make sure everything is up and running on the new computer before doing that.

8) Note that moving a database to a new copy of Metron-U (as above) is pretty simple. It is more complicated if you have two databases that you need to "merge" together into one. So, unless you have a good reason to do so, we recommend you keep all your cases on one computer in one database.

9) If, on your new computer, you see your data but Metron-U is acting weird and not remembering new things you enter into it, then you probably didn't do step number 5.6 above.
