How can I correct System Information.app 10810 error

I am running Mavericks 10.9.3 on my late 2012 Macbook Pro. I used to be able to run System Information; however, now when I run it I see an error The application "System Information.app" can't be opened. -10810. I've poked around on the net, Googled mostly, and have not found anything specific to my issue. Finder, btw, runs fine and I have not yet seen this error with any other app. Can anyone point me in the right direction to research or help me correct this problem?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

How can I obtain System date and time?

Good morning to everyone !,
Could anybody help me?
I need to know how to get the current System time... ??
I need the source code to get it as a Timestamp. I think this type belongs to the class java.sql.Timestamp
Which is the easiest way to do this?
I need to get it, to insert it in a database datetime field afterwards.
Thanks in advance for your time.

Hello again, thanks for all the kind replies...
I think I will go for this Option:
Timestamp time = new Timestamp(System.currentTimeMillis());Seems very coherent to me. Do you know If I can insert it inside a datetime field of a DB Table?
Thank you guys, you always exceed my expectations
Sincerely, Jose

How can I obtain the primary key of a table for an entity relation?

hello everybody
I am doing a consultation to a table in my data base, good this table has alone two fields, the first one is the code or pk and the second one is the description, to be presisos they are names of city and code.
From the beginning!!: This method this one in another class that is a Dialog that is going to call to the class SelecPlace ();
SelecPlace sl = new SelecPlace();
public void capturarLugar(){ // Simple void method in the mentioned class
        String place = txtProcedencia.getText() ; // a JTextField
        sl.executeStatement(place) ;
    }ok, now we see part of the code of the class SelectPlace
public class SelecPlace extends AbstractTableModel{
    Connection con = null;
    Statement sentencia = null ;
    ResultSet rs = null;
    ResultSetMetaData rsmd = null ;
    String[] nameColum = {} ;
    Vector datos = new Vector() ;
    public SelecPlace() { }
    public void executeStatement(String query){
      try{
         con = DBManager.getConnection() ;
         sentencia = con.createStatement(rs.TYPE_SCROLL_INSENSITIVE,
                                                                      rs.CONCUR_UPDATABLE) ;
         String sql = "select * from Place where descripcion like %"+query+"%'";
          rs = sentencia.executeQuery(sql) ;
          rsmd = rs.getMetaData();
          int nroColumnas = rsmd.getColumnCount() ;
          nameColum = new String[nroColumnas] ;
          //obtengo los nombres de columnas en cache
           for(int colum = 0; colum < nroColumnas; columna++){
                nameColum[colum] = rsmd.getColumnLabel(columna + 1) ;
           datos = new Vector();
            while(rs.next()){
                Vector newRow = new Vector();
                for(int i = 0; i < getColumnCount(); i++){
                newRow.addElement(rs.getObject("place_ID"));
                newRow.addElement(rs.getObject("description"));
                datos.addElement(nuevaFila);
            fireTableChanged(null);
        }catch(SQLException e){
            System.err.println(e);
            e.printStackTrace(System.err);
            System.out.println("error in statement");
        }catch(ClassNotFoundException cnfe){
            System.err.println(cnfe);
    }Ok, this code me works and I obtain in this case the field description of the table Place

Certain duffymo and everyone!!, good I give you my scheme:
And generalizing my question, I want to obtain the value of the primary key of a table in the database, I obtain more values of the same row, but I need the primary key, and you see one with the primary key I want to turn a Long and it to insert with code java in foreign clave in another table of the database

How can i reload font information while the jvm is running.

l.s.
how can i reload font information while the jvm is running.
I'm having the following problem...
A program is running.
A user installs a new font on the system (Xwindows in this case)
Java doesn't display the font when i ask :
java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();Thus i think that java buffers its font information somewhere. Anyone knows how to refresh te buffer?
many thanks

They have Cs6, however I need to have my own copy, and the highest I can go with my system is CS5, maybe even 5.5. I've a small budget, and most copies are being sold for massive amounts because they're like collector items. I've seen the ones actually affordable within my range from sellers that arent trustworthy, or they're updates which I can't use. I had Cs2, but with updates to operating systems they stopped working. Thank you for your kind assistance.

Thanks in advance and best regards

If your computer shipped with Mac OS X 10.6.8 or earlier, install them from the computer's original disks.
If your computer shipped with Mac OS X 10.7 or newer, log into the Mac App Store with the Apple ID used to register the computer, click on the Purchases tab, and download them.
If neither of these is applicable, buy them from the Mac App Store.

How can I obtain the first 10 charcter from field and the last 4 characters

Hi
   I need to obtaind the first 10 characters from field AWKEY from BSEG table, and the last 4 characters, how can I obtain certains position from field??
    Example:
AWKEY field from BSEG can be for example :
51000573112002
   This mean that you can obtain separately:
5100057311 - BELNR (field)
2002- GJAHR (field)
    As you can see, the first 10 positions are BELNR and the last 4 positions are GJAHR.
     But sometimes you find in old rows:
5100057312US502001
     This mean that you can get from this field:
10 positions for BELNR : 5100057312
4 positions for BUKRS or WERKS : US50 - in this case, I don´t know if its is BURKS or WERKS...for this reason only I want to take only the first 10 positions and the last 4 position to compare.
4 posiition for GJAHR: 2001
   I rewards all the answers.
   Thank you.
Alicia

Hi, thank you for yours answers
Let me try to explain more what I need to do:
I have a Internal Table that I create with EKBE table:
SELECT MANDT EBELN EBELP GJAHR BELNR BEWTP BUDAT
          MENGE WRBTR WAERS WERKS SHKZG DMBTR
          ZEKKN VGABE BUZEI
    INTO CORRESPONDING FIELDS OF TABLE LIST_EKBE
    FROM EKBE
      WHERE EBELN IN R_EBELN
        AND BEWTP IN ('E','Q','R').
The result is all the rows that have this conditions..then with this internal table I need to looking for each BELNR in BKPF table, but sometimes you can find the row compare EKBE-BELNR with BKPF-BELNR...but in many cases, you don´t find the row in this way, you need to add EKBE-BELNR and EKBE-GJAHR and looking for in BKPF with field AWKEY..
For this reason I CONCATENATE in this way:
LOOP AT LIST_EKBE.
    V_BELNR = LIST_EKBE-BELNR.
    V_GJAHR = LIST_EKBE-GJAHR.
    CONCATENATE V_BELNR V_GJAHR INTO V_AWKEY.
    SELECT SINGLE MANDT BUKRS BELNR GJAHR AWKEY
    INTO (BKPF-MANDT, BKPF-BUKRS, BKPF-BELNR,
         BKPF-GJAHR, BKPF-AWKEY)
    FROM BKPF
    WHERE AWKEY = V_AWKEY.
ENDLOOP.
But I saw that sometimes you don´t find the record in BKPF because the AWKEY is formed with BELNRBUKRSGJAHR....or may be with BELNRWERKSGJAHR ...I don´t know if is BUKRS or WERKS the second field...for this reason I try only read in the select..if its posible the first 10 postions and the last 4 positions...but Im not sure if its possible..
The reason for that I looking for the BELNR field in BKPF field for AWKEY its because sometimes de BELNR in BKPF its different..example:
In EKBE you have:
BELNR: 5105618260
GJAHR: 2006
If you looking for in BKPF you don´t find sometimes exactly the field BELNR : 5105618260.. then you need try looking for the AWKEY field then you need to add BELNR+GJAHR..example:
BKPF:
BELNR: 5105611111
GJAHR: 2006
AWKEY: 51056182602006
But in other cases... I found that in AWKEY exist for example:
BELNR: 5105611111
GJAHR: 2006
AWKEY: 5105618260US502006
In the last case I supouse that I can divide in:
AWKEY: 5105618260-US50-2006 ... but I don´t know what its the field that have the information US50..may be is BUKRS or may be its WERKS
May be some people know what its exactly this field and can help me..
With the solution that some of yours give me..I don´t know the how I can make the select? and if its posible make in this way
Thank you a lot

I need to install photoshop cs4 extended from a disk to a new computer because my old computer had a hard drive crash. There is no serial number on the back of the case. How can I obtain a usable serial number?

I have to install Photoshop CS4 extended on a new computer from a disk because my old computer had a hard drive crash. There is no serial number on the back of the case. How can I obtain a usable serial number?

Find your serial number quickly
You can activate software without following up and registering it... at least that was the case in the past. The serial number is normally located on the disc case or a box inside the main box. If you did not purchase the disc from Adobe then it is possible you would have dealt with a redemption code, in which case it would have been up to you to keep a record of the serial number, especially if you did not follow up and register the software.

In Contacts version 8, how can I print ALL information in each individual card? When I select the print command the only thing printed is the name and address. I need phone number(s) and all other information in the cards.

In Contacts version 8, how can I print ALL information in each individual card? When I select the print command the only thing printed is the name and address. I need phone number(s) and all other information in the cards. We enter various pieces of data, other than the standard name address & phone numbers and we print all information on each card so it fits in a 5x7 inch loose binder. We have used InTouch software for many years and it has served us extremely welll, however, the publisher (The Prairie Group) has not, and apparently has no plans to update their software to be compatible with any Mac OSX OS beyond 10.6. Any help will be appreciated!

You can select what you want included in a list format. In the Print command from Contacts, click the Show Details button. Then in the Style pulldown menu select "Lists" and there you'll be able to select what you want included. You can also select what you wish included if you select the Pocket Address Book style.
If neither of those options will work for you, then you will need to look to third-party software. Here's one possibility that seems to get good reviews:
https://www.macupdate.com/app/mac/15485/labels-&-addresses
I haven't done more than try it to make sure that it works with OS X 10.9's Contacts, which it does, but you can download their demo and try it yourself.

How can I delete the information in iPod touch because I lose it.

Hi,
I lose my iPod touch yesterday and all information in there. How can I delete those information?
Cheers.

- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up.
- You can also wipe/erase the iPod and have the iPod play a sound via iCloud.
- If not shown, then you will have to use the old fashioned way, like if you lost a wallet or purse.
- Change the passwords for all accounts used on the iPod and report to police
- There is no way to prevent someone from restoring the iPod (it erases it) using it.
