Idea2020.3.1 cannot be opened (double click cannot be opened), but it can be opened through idea.bat.

Very interesting ,IDEA I can't open these two days , Monitor through task manager , Find out IDEA The process of disappeared inexplicably after only two seconds , So it came to IDEA Under the installation path of , Open the idea.bat, As soon as the black window comes out , It can be opened .

my idea.bat The file in F disc , The path is shown in the figure ：

Next, double-click to run , Pictured ：

you 're right , As shown in the figure ,IDEA It's working ！！

So that's it , I didn't care for two days , Recently, I still want to find the reason , Many people say it's because Visual C++ The problem of . Many people are systematic Visual C++ Something is wrong. , There are also accidentally deleted , And uninstall C++ Caused by the development environment . I know I may have been Visual Studio 2019 Extended above C/C++ Development environment of , Lead to Visual C++ The version or path of is changed , because VS Maybe put the old Visual C++ Deleted , I reload again , It is possible .

For whatever reason , Nine times out of ten, it's Visual C++ problem , You can try reinstallation IDEA, Or download Visual C++.

Support the latest Visual C++ Redistributable package download | Microsoft Docs

Of course, other problems are idea.bat The black window will show , But I can open IDEA That's it , I created a shortcut on the desktop , Link to local idea.bat, And rename .

 

The icon is right here IDEA Search under the installation path ico You can find IDEA The icon .

I didn't try the solution , Because I'm too lazy to reload IDEA 了 , And we have to reconfigure some things , Such as Maven, Annotation rules and so on .

———————————————————————————————————————————

It took five days , I didn't want to solve it , But I found that many applications have inexplicable problems , And there are hints vcruntime140.dll Problems in , Of course , This sum IDEA irrelevant , But this indirectly shows that C++ Library problem （ Via Baidu ,.dll So is the problem C++ error ）.

therefore , The last straw , I pretended before and after C++2013（ success , But it still hasn't solved the problem ）,C++2015（ Failure , Already exists , uninstall C++2013 failed ）. The result is found in the control panel ：

  The one above is x64,64 For bit system , The following is x86,32 For bit system （ At that time, the installation date of the two files was the same , It's the fashion I mentioned above C/C++ When the environment appears ）, Double click according to your own system C++ file ,

  The picture above , Click repair , then , Have you found IDEA It can be opened ！！
