Arellia Agent Uninstall Fails

Problem:

The Arellia Agents fail to uninstall after enabling the uninstall policy of either Application Control Solution, Local Security Solution, or Security Analysis Solution Agents for Windows x86 and x64 clients. This failure produces a 1605 error meaning that the uninstaller was unable to find the product specified. The reason for this failure is because of an incorrect GUID being in the Agent Package.

Solution:

Open the Arellia Console and click on Configuration.
Navigate to Settings->Agents/Plug-ins->Arellia->Application Control->Application Control Agent Rollout
Select the Application Control 7.1 x64 Agent Package

```
{ee4a2f47-fbee-4c05-b86d-17ff6d9cf1ab}
```
to the correct GUID:
```
{D3A0E295-1F80-428F-86E7-65CF05A37B91}
```

```
msiexec /x {D3A0E295-1F80-428F-86E7-65CF05A37B91} /norestart REBOOT=ReallySuppress /qn /lvx\* ACSUnInstall.log
```
