Install javaw.exe

I watched the tutorial that explains it well. Except that Revo Uninstaller didn't find Java either.
I thought about restoring my computer before the accidental deletion of JAVA, but that is impossible to do: the computer keeps showing that an error has occurred and that the restoration could not be done.
Honestly, I'm bothered.
I will try the method proposed by franqui34 and if not, well I will make do with my broken computer. What else can I do?
Thank you both.
I'll keep you updated on what happens next.

Good evening and thank you very much franqui34 for your response.
I tried to download the Java software but it's impossible to do.
It must be because I accidentally deleted this software and there are probably traces left on the hard drive that prevent any reinstallation. That's the only thing I can think of.
What do you think?
However, to use another software, I'm being asked for Java...
I will try to do a previous restore.

Good evening,

Have a nice evening.

Hello,

Download this --> utility
and install it as an administrator.

After the installation, go to start
All Programs
Right-click on --> windows installer cleanup
Choose --> run as administrator and confirm
Launch it

Select one box at a time for everything related to java, sun, oracle, etc...
Click on remove.

Restart the pc
Go delete the folders --> java
In --> C\program files and program files (x86)

Launch CCleaner as an administrator for cleaning in windows, applications and registry.
For using CCleaner, check this --> tutorial

If you have a 64-bit windows version:
Install both offline versions --> Java
If not, install only the 32-bit version.

Thank you both for your responses. I will do what you suggested.
I’m sending you the messages I received during the reinstallation of the software that was accidentally deleted:

kaneagle, I wanted to register msicuu-7.2 but it's asking me to register this software as an administrator, as you mentioned. But how do you register as an administrator in this case?
I read the procedure that franqui34 provides, which seems effective as well.
I want to emphasize that I'm putting in a lot of good effort because I'm completely clueless about computers.

You download and save it in your documents.
Right-click on the setup and choose --> run as administrator.

Ok Kaneagle, I started with you and I'm continuing. Hopefully, you stay online!!!!
I clicked on run as administrator.

Follow the procedure closely.

I went to Windows Installer Cleanup but at no point do I get the option to click on install as administrator.
Moreover, I see a list but I don't see JAVA or ORACLE at all:

Where do I click now, please?

There is nothing to do if no Java appears in the list.

Try uninstalling it with --> Revo-uninstaller

When I type javaw.exe, Revo Uninstaller finds nothing.

Java must be uninstalled properly.
Check out this tutorial --> Uninstall a program with Revo Uninstaller

Try with javara and if it still doesn't work:
Go to start
All programs
Accessories
Right-click on --> command prompt
Choose --> run as administrator and confirm
Type: sfc /scannow and enter

A system file check will be performed.

Thank you, Kaneagle.

So everything is okay?

No. It's stuck with Javara. I followed the instructions given meticulously and I clicked on download half an hour ago and nothing is happening. Should I wait longer?
Well, I will move on to your last message: go to start....
I'll keep you updated.

The scan is finished and everything is fine since it says: "Windows found no integrity violations."
I did everything that was advised to remove the remnants of JAVA and download a new version and my system is good.
I'm giving up but I'm not marking it as resolved in case someone with a great idea shows up.

Thanks again Kaneagle.

While I had given up any idea of reinstalling JAVA after all my unfortunate attempts, I finally managed to install it by chance by asking in another discussion how to merge my PDFs other than through pdfsam. In response, an internet user gave me a link for JAVA that I opened without hope, and there it was, JAVA installed.
In any case, I thank you very much franqui34 and kaneagle for your help.
I am marking it as resolved.
Have a nice day
