I am a user of IntelliJ IDEA, and it used to work properly. Yesterday, I removed Visual Studio 2019 from my laptop, and also some program files named 'Microsoft Visual C++ 2008 Redistributable ...'. Then I installed Visual Studio Code.

Suddenly, when I double click the icon of IntelliJ IDEA, the opening screen doesn't appear at all, and nothing happens. I checked the operations going on, and there was nothing. This was the same when I clicked idea64.exe (my laptop is Windows 10, 64 bits) But when I tried idea.bat, the cmd opened with the following error, and IntelliJ opened properly.

What's the problem and solution to this? How can I open IntelliJ IDEA properly by only clicking the icon that leads to idea64.exe?

I met the same problem as what you said. I run the idea64.exe as administrator mode, it can be launched correctly. Very confuse me.

You have to put the agent jar file under the Jetbrains of the Program Files.

In my case I originally installed Intelli in my windows machine user account. When I log using that account I have no issues. I've since then created a new domain user account on my machine. When I logged onto that account and tried to access the Intellij IDE that's when I observed the same issues that Choi had. I was able to start the IDE if I ran it as administrator. I went to the folder where the IDE was installed and gave myself full permissions. When I did this, I got further along, but I got some issues accessing some dll in the AppData directory. It might have been the AppData directory for the user account that the IDEA was originally installed with (I don't recall for sure). If it was the other user account that certainly explains why the IDE might have issues trying to access that dll. The short of it is that I came to the conclusion that trying to fix the problem by correcting permission issues seems to be problematic. I opted to just reinstall the Intellj IDEA again. In my case there was a newer version of the IDE available, so I would have been doing that anyway.

Choi's case seems to occur for some other reason than my situation. It's certainly baffling to think that uninstalling a non-related product would affect on how the Intellij IDE works. Removing the MC VC++ Redistributable should not have any effect on how the Intellj IDE starts up. I think those activities are not related as to why your Intellij IDEA won't start. From my experience, I've learned that file permissions issue can cause the observed symptoms. Perhaps in doing the delete of this non-related software, Choi unintentionally messed up some file or directory permission. At any rate, that's water over the dam. My suggestion would be to reinstall the Intellj IDE.
