Problems while trying to install JDK in windows 7

Hello,
I tried to install latest JDK version: jdk1.6.0_21 on my windows 7...
I have set the Variable in USER VARIABLE as:
NAME: PATH
Value: C:\Program Files\Java\jdk1.6.0_21\bin
Now, When I went to the CMD and typed "set" it showed me
CLASSPATH=.;C:\Program Files (x86)\Java\jre6\lib\ext\QTJava.zip
Now, I am not sure what to do after this? Am I on the right track or doing something wrong?
I really want to be able to install this ASAP so I can start using/learning JAVA Programming from very basic.
Instead of using Netbeans I want to use this command prompt to be able to learn java.
I want to type all my codes in this CMD thing and be able to store and view all the files from this cmd / folder.
So, waiting for your response :)

You really do not need to change your classpath. There are ways around it (search the net).
Once you have changed your PATH variable open up a new command prompt. Type
java
javacIf the responses you get back are about the usage then you have set it correctly and can now compile and run your programs. If you get back an error saying that it cannot find the program then your PATH is wrong.
You might also want to try
java -version
javac -versionto confirm that you have the correct version installed.

Problem while trying to install OVI suite

Hi, guys! How you doing? I've got a problem while trying to install OVI Suite: I'm getting a warning signal that says "Something got wrong - Nokia Ovi Suite installations require that PC Connectivity solution 7.0.0.0 or a later version to be already installed before continuing installation" and I can't install after that. I've been searching at Google, but I have found nothing. Hope you can help me. Thanks in advance.

Problem while trying to install MS tools for PDA

I'm using Windows XP service pack 2 (new PC at work...), and I get the message "'Windows CE Emulator' will cause Windows to become unstable. Windows has prevented these drivers from loading." while trying to install the eVC4 package required to run the LabVIEW PDA Module.
So far, no way to solve the problem, even trying to follow/understand the "Help and Support" file that is proposed by Window.
Any hint ?

"Error 1721" when trying to install jdk-6u3-windows-i586-p.exe ??

When I try to install the just downloaded jdk-6u3-windows-i586-p.exe
= Java SE 6 upd 3 Development Kit on my WinXP computer at first everything seems fine.
I can choose the installation options (all except the Java DB).
and selected the installation folder and start the process.
The progress bar reaches approx. 80%.
Then suddenly it stops and a popup appears:
"Error 1721. There is a problem with this Windows installer package. A program required for this install to complete could not be run".
What's wrong ?
BTW: Upd 2 could be installed without problems.

Hi, Try reregistering the Windows Installer service.. For that restart you system in safe mode then
Open command prompt and excecute the below commands
1 msiexec /unregister
2 msiexec /regserver
Restart the system normally and check if it works.
If it doesn't work try using some registry cleaner like CCCleaner to clean your registry.
Hopw this will work ..

Problem while trying to install a visual editor for eclipse

Thanks

Error 13042 while trying to install

When first trying to download reader X I was getting error: The download did not pass the integrity check (16299.304.450) at 83%
Checked here on these fourms for a solotion and found get.adobe.com/reader/enterprise . That link worked for downloading however I am now getting the error 13042 while trying to install.
Running Windows 7 on an Asus F3JP notebook. Thats about all I can tell you, if you would like more info please let me know, you may have to tell me where to find it though.
Thanks for your help with this matter.

This error is related to the failed extraction of the compressed files.
My best guess is that your download is corrupted.
Try to download "MSI" version of the installer from Adobe FTP (the links are posted in this forum frequently), which would get you to 10.0.0
Than you can manually update to 10.0.1
Good luck

Error while trying to install SAP CE 7.1 EHP 1 on Windows 7

I am trying to install SAP CE 7.1 EHP 1 on Windows 7. I am getting below error while trying to install. can you please help to fix this problem?
Running msiexec failed with return code 1603: undefined
Commandline was msiexec.exe /norestart /L sapmmcX86u.log /i sapmmcX86u.msi /qn
If you want the installer to retry, choose Yes. If you want the installer to abort the installation, choose No.
Thanks,
Sridhar.

I donu2019t think so it is windows 7 or 64/32 bit hardware/software issue. I have faced u201Cmsiexec failed with return code 1603u201D error many times during SAP installation and solved this issue with below mentioned procedure.
Solution:
Just change the location of temp directory to empty folder in user environment variable without cancel installation in current user session. After that, click on yes button to continue the installation. If installation will ended after click on yes button, restart the installation with continue old installation option.
Regards.

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
