Add another sentence: Do not self-righteous, arbitrarily delete all of the registry related to Oracle - that may result in unavailable Oracle, or you may detect key values or items of other software! It is already enough to delete more than a few items. In addition, I have encountered a strange phenomenon - the Oracle9i installer on the company's server can only be installed once on a machine, which is not re-installed, even if it is a leather system! ! I found a new installer from my friends to get it. Too strange ~~~~~
