The RDP templates located in the SCALUS folder located in (C:\Users\{Username}\Downloads\Patches\SPP Patch\SCALUS) had an incorrect value for screen mode id setting. There is a typo semicolon in the line screen mode id:i;1
This issue is fixed in SCALUS version 1.1.0.471 when SCALUS is installed as a fresh new installation but an in place upgrade does not replace the existing RDP template files.
Note: The in-upgrade of SCALUS did not replace the existing RDP template files in case there are other customized settings that should be preserved.
If no customized settings exist in the RDP templates:
Uninstall the older version of SCALUS first and Delete the SCALUS folder in this path (C:\Users\{Username}\Downloads\Patches\SPP Patch\SCALUS)
Then install the new release of SCALUS which will recreate the SCALUS folder with the updated RDP templates that include the fix for the screen mode id setting.
If you have existing customized settings in the RDP templates:
Manually edit the RDP templates in the SCALUS folder path (C:\Users\{Username}\Downloads\Patches\SPP Patch\SCALUS)
To correct the line screen mode id:i;1 by updating the semicolon to a colon screen mode id:i:1 and save for each RDP template.
