Before migrating Informatica client tools to Informatica 10, I had to uninstall version 9. On starting the uninstaller, I got immediately this error in Windows 7: “Windows error 2 occurred while loading the Java VM”. To run uninstaller, run this command from command line with Administrator privileges C:\Informatica\PowerExchange9.5.1\Uninstaller_pwx\Uninstaller.exe LAX_VM “C:\Program Files (x86)\Java\jre1.8.0_101\bin\java.exe”
