If you have Symantec PCAnywhere 10.x or earlier version installed on the managed device and are upgrading Remote Management Agent, you need to be aware of the following:
Selecting Mirror Driver in the Remote Management Agent install may lead the managed device going into low resolution or VGA mode. This occurs because PCAnywhere does not support coexistence with Remote Control solutions based on hook driver technology. The Remote Management hook driver that ships with ZENworks 6.5 has been deprecated and is no longer being installed on the managed device during upgrade.
To resolve this issue, do the following:
Reinstall the system video driver on the managed device.
Reinstall PCAnywhere on the managed device.
Upgrade Remote Management Agent with Mirror Driver.
NOTE: You need to execute this step only once. Subsequent upgrades does not require this steps to be executed. Hence, we recommend you to install Mirror Driver.
If you choose not to install Mirror Driver, you will not encounter the low resolution or VGA screen problem. However, the remote sessions would not be optimized for performance without Mirror Driver. Hence, you will need to execute rmsetdrv.exe to enable the hook driver, which is deprecated with ZENworks 6.5.
To resolve this issue, do the following:
Upgrade Remote Management Agent without Mirror Driver.
Run "rmsetdrv.exe /hook".
NOTE: You need to execute rmsetdrv.exe everytime you upgrade without Mirror Driver. Also, hook driver is deprecated with ZENworks 6.5. Hence, we recommend you to install Mirror Driver.
