Problem: Open pb is usually displayed on the left side of the workspace, but now the result of my computer tree is displayed.
Solution: Right-click setroot to set root to current workspace. In this case, my computer is displayed on the left when pb is opened again. This is because of the consequence of getting pb dll files to system files. Delete the pb dll files in the system file directory, system folder (windows/system32) and the folder where the program is located. Do not keep any pb dll. (This is the answer found online ).
Test: But after my test, there is no pb DLL file in the windows/system32 directory. But ~ The problem still exists. In the above statement, it seems that the problem lies in the pb dll file. So ~ I conducted a test to view the search path of the system file.
When I see the directory under E ~ I came up with an idea. The E: \ *** directory is the one specified in the previous day for the Test System in the environment where no PB is installed ~ After the system passes the test ~ I only install PB. Therefore, the Directory of PB installation is located after my E: \ *** directory ~ Some situations are like those mentioned on the Internet ~ Because, in this case, when starting, PB ~ The system files under my E: \ *** may be called first. Let me remove this content
Restart the machine ~ Start PB ~ Haha ~ The problem is solved.
Conclusion: These problems are indeed related to pb dll files ~ However, in addition to the conclusions obtained on the internet, pay attention to the content of PATH settings.
