Error Message :
N/A

In the case of the UVC Web Console:

Patch level detected:Univiewer Console 6.2.00
According to the product documentation, it should be possible to modify the directory where the webconsole stores its parameters on a local disk.

However when adding (for instance):
 

to  /webapps/univiewer_webconsole_6.x.xx_all_os/WEB-INF/conf/UVC_config.properties file,  it is not parsed even if it does appear in the downloaded JNLP file.

The variable uphd_enable=true that may be necessary, does not change in the JNLP file.

In the case of UVC standalone (installed locally):

According to the product documentation, it should be possible to modify the directory where UVC stores its parameters on a local disk.

However, the indication in the documentation is incorrect:
 

Defect
Root Cause: The uphd variable was not taken into account.

OS: All
OS Version: All

Update to a fix version listed below or a newer version if available.

Fix Status: Released

Fix Version(s):
Univiewer WebConsole 6.2.41 - Available

In the case of Univiewer standalone use:

jnlp.uphd=D:\\$USERNAME$ (instead of just uphd) in <UVC>\data\uphd.properties

(this will be corrected in the documentation in the future)
