Windows cannot run. the bat file solves the problem of installing MyEclipse10.1 on your computer today. During the cracking, you need to run in MyEclipse10.x registration machine. bat file, but when you double-click it, the computer cannot run, I don't know why, I think it may be because my computer re-installed the system, but after I find my computer cmd, you cannot execute the doscommand in C: \ User \ Administrator>, but you can run the doscommand in C: \ Windows \ System32>. I think it is a configuration problem, later I learned that it was an environment variable problem. You can set it as follows: C: \ User \ Administrator> and enter the command set path = % path %; C:/windows/system32, this indicates that C:/windows/system32 is added based on the current environment variable (path already has a value), but this is only valid for the current operation and can be used temporarily, to permanently modify the environment variable, In fact, it is the same as configuring other environment variables (such as the JDK environment variables of java). Right-click my computer and choose Properties> advanced Properties> environment variables> Add them after path, separate them with semicolons --> Save. Run now. the bat file is enough. By the way, when installing MyEclipse10.x, you can run the registration machine run. bat file, follow the steps in it and do not be misled by the cracking instructions on the Internet. By the way, I am talking about installing in windows, and my installation environment is windows 7 64-bit! Note: run. bat is actually a java file. To run it, first install JDK on your computer and configure the environment variables!
