Win7 under the DB2 Express-C 9.7.2 uninstall and install
Benpian too long, introduced Say what : install the system requirements, installation diagrams, interface garbled Chinese box solution, the tools catalog database installation (DBA1176N),command line start.
Now start the installation, installation, start with the system requirements.
Up hard disk space ranging from about 600 ~ 1300M, product of disk space required depends on the type of installation, and have selected the file system type. "DB2 ® installation" wizard will be based on a typical installation, streamlining the process of installation or custom installation components selected to provide a dynamic size estimates.
For the precious memory, most people should be more concerned about the, DB2 database system requires at least 256 MB RAM. Only run for a DB2 product and the DB2 GUI tools of the system, at least 512 MB RAM. However, the proposal provides 1 GB of RAM to improve performance. These requirements are not included in other software running on the system memory required, or a little cruel.
More details refer to here , no installation files for the speed to go here to download. Get is a 398M download the db2exc_972_WIN_x86.exe file, double-click it to run. When installed it will extract the installation files to the system temporary folder, then run, in fact, this is a compressed package, you can use 7zip tool to extract out of a picture can not be extracted in addition to the other outside the normal, after the installation directly from the extract from the file to run, can save some time.

Next, choose a typical installation is enough, you can also choose custom, then later you can see more options, generally can not control, so the next step directly here 
Response file, which is used to automatically install. Sometimes, you need to install the DB2 client on multiple machines, or DB2 database server needs to be embedded into the application, and install the application to install the DB2 database server. These cases, DB2's automatic installation is an ideal way. DB2 using a response file to automatically install the response file is a text file, save it to install the required information. Here directly the next step 
Select the installation folder 
User account configuration, novice only enter the password and confirm the password, the other unchanged, the next step. For those who know, you can enter an existing user, the user will use an instance of DB2 and other services. The user must be a local administrator in windows (Local Administrator) of a group, and operating system log when the password is the password used. If you enter a user ID does not exist, the user ID will be created, and as a local administrator, that a new system administrator. If the user does not belong to any one domain, add the domain (domain) blank. Windows, the default is to create a user name db2admin. Here, I chose to use the current landing system user account (preferably an administrator uncle) 
Configuration example, you can do some configuration, for example, is turned to start the service, the next step directly here

Sometimes the interfacebox will appear, which is Chinese garbled, like a close re-start, not try more than once. If does not work, I used the experience: countdown third point of the toolbar icons, tools set out, point the third tab (font), the first drop-down box, just a change of values, restart the control center interface on the Well, not so complicated that the Internet, then you can then change back the value, the default values see the next figure.
