During oracle installation, the system prompts that the program Input Point getprocessimagefilenamea could not be located and solved the problem two days ago on the Dynamic Link Library PSAPI. DLL. The final success: one person has completed the following steps. I hope you will be cautious with the hard-pressed programmers. The installation environment is as follows: OS: win7 sp1 oracle Client Version: oracle920 no table pc components. Solution: delete all installed oracle versions completely (there are a lot of online materials, so it is not recommended ). Right-click computer> Properties> Advanced System Configuration> environment variables. Among them, the system variable: the value of the variable path is E: \ oracleClient \ bin; the value containing the oracle path is deleted, and other values remain unchanged. Note: variable values are separated. And then reinstall.
