Cannot reinstall XE 18c after doing an uninstall

RabbitWolfMar 29 2019 — edited Mar 29 2019

Hi,

I successfully installed XE 18c on my Win Pro machine. After a few days, the OracleOraDB18Home1TNSListener service would start and immediately stop. I thought I would try uninstalling and reinstalling XE 18c. However, the even though the uninstall finished and I rebooted my system, the uninstall did not do its job. When I tried to run the installer, I get this stuck at this point:

Why does the installer think there is already an existing XE database? Pressing NEXT does nothing. What is the installer checking that makes it thinks there is an existing installation? How can I force the installer to do the installation?

The reason is simple, the uninstaller only does half a job.

If you run the services.msc utility (Windows +R, type services.msc), scroll down to the Oracle named services and you will see a few that are still there. You need to get rid of those as follows:

start

Search for cmd

Right-click, run as adminsitrator

When it runs:

sc delete service_name

For each and every OracleXE service you see.

Then try the installer again.

When you look at your services, do you see an XE service?

Thank you so much. This solution worked for me. I was able reinstall XE after deleting below services in my system.
sc delete OracleOraDB18Home1MTSRecoveryService
sc delete OracleOraDB18Home1TNSListener
sc delete OracleOraDB19Home1MTSRecoveryService
sc delete OracleOraDB19Home1TNSListener
sc delete OracleServiceORCL
sc delete OracleServiceXE
sc delete OracleVssWriterORCL
sc delete OracleVssWriterXE

How to Uninstall Oracle Database 21C | RebellionRider (0 Bytes)Regards,

user-6k6y2

when I try to delete the oracle services it shows ‘The specified service does not exist as an installed service.’. I'm trying to reinstall oracle and it's delivering the same message that it exists on my machine. how do I fix this?

user-q5oby

Hello,

I have several times tried to install Oracle Database 21c but there is an error INS 35955.

How can i fix this problem?

Thank you in advance.

That is not XE (which is what this forum is about). You are trying to install Enterprise Edition. It may be easier to install Express Edition if you do not care.

In any case, it looks like you have already installed once and didn't successfully uninstall.

You can try renaming that dbhome directory to something else and then rerunning setup from there.

Thank you.

This worked well!
