I was attempting to uninstall Oracle 11g database and do a reinstall because of some tns and listener errors. I am on Windows 10 and was uninstalling from the Control Panel. However, my uninstall window got closed toward the end (by my own mistake) and now when I go back the Control Panel, it still shows an entry for "Oracle Database 11g Express Edition" which is of 53.1 MB only; initially this was some 600 MB so I believe the uninstall happened partially when it got aborted.
Now it doesn't let me uninstall anymore, it gives me an error "1628: Failed to complete installation.".
I have tried reinstalling the software using the Oracle universal installer but that only gives options to Repair and Remove. Clicking Repair or clicking Remove gives Error 1605: This action is only valid for products that are currently installed.
I have followed the steps to remove Oracle key and any traces of Oracle from registry and all other locations documented in
https://oracle-base.com/articles/misc/manual-oracle-uninstall#Windows
Despite all this, I haven't been able to resolve the problem and move past the error. I even tried a system restore but unfortunately there were no prior restore points save
Is there any tips someone can give me that will help my situation? I would be really grateful as these issue have stalled my work.
