Hello

I'm upgrading DC(Data Collector) and Clients on Windows server.

But there are some problems.

We were originally using the DSM version of 19.1.20.30, and we tried to upgrade to log4j path.

(19.1.20.30   ->   20.1.2.14)

However, the following error occurred even before the upgrade process started.

 

I've tried installing it on several sites in the same environment, but some have succeeded, and some have errors like that picture.

May I know how to solve this problem?

I really ask of  you

 

 

Additionally, I tried this kind of work.

1. Proceed with upgrade / Proceed with upgrade file administrator authority.
2. File upgrade / Data collector client installation.
3. File file, $appdata$\component File.
4. Delete files uploaded to each country in Korea, download them locally, and reinstall them.
5. Register Windows installer / again.
     a. Msiexec.exe / Unregister.
     b. This is msiexec.exe/regserver.
6. Restart the Windows installer service.
7. Reboot the window server.

Thank you
