@DELL-Scott H  here is ! Idk how we can attach the the log.. But i send all the infos here!

What is the name of the file you are using to upgrade WMS?

I removed some sections of the log you posted as it had some possibly sensitive information in it. 

I see the following in the log (in Red)

Can you check for the presence of this file?

Also, I have seen very odd behavior in the past when security tools/Antivirus are running.   Can  you check those logs or try the install with it disabled?

@DELL-Scott H​ My name is Paulo and Arthur is my partner, he reached the limit of answers, so we check the presencence of the file, and the file is not present. I am attaching the evidence

The original name the website gave it to me WMS_5.1.0.351.exe

Hmm.  I wanted to make sure you were running the WMS installer and not the repo installer, but that looks right. 

I am afraid I don't know what is going on.   Have you looked at the Antivirus/security tools logs or tried disabling them?

I tried to remove the antivirus, but the same error occur.

You know how i can reinstall from scratch without losing settings ?

I just thinking in another possibilites to update that...

I dont know how many thin clients you have or what type but I have seen many customers just install on a new server, setup their policies again and use the policy on the old server to move them to the new server.

Since WMS free does not come with support, I am not sure what else I can suggest.

@DELL-Scott H​ cold you indicate the policy to move the devices for the new server? do you have any articles about that?

I am sorry but I do not. 

Assuming you're devices are ThinOS9 or above, Take a look at the Services>WMS Settings for a group. 

• Enable Advanced Configuration
• Use the Server field to specify the new server, and the group prefix and token to specify the new group.

Test on a small group of devices first of course. 

Using this you can "Instruct" a group of devices to move to a new server, or even the cloud hosted if you purchase Pro.
