Known
Issues
7.1 Description:
File comparison may result into ‘Fatal error’ due to insufficient privileges
(administrator) on Win 7 or Win 8 or Win 10 when UAC is disabled.
Details: The defect is observed when a standard user
is running Unity DIF. A standard user process has no means of elevating the
privilege level to administrator when UAC is disabled. Unity DIF process
requires elevated privileges to run.
So it can run,
1) Only when an administrator
is logged on
OR
2) A
standard user (with UAC turned on) authorizing the program with administrator
credentials (Run as administrator)
7.2 Description: The
comparison of same project files after downloading and uploading from device or
simulator without any user changes results in some irrelevant differences.
Details: The process of downloading and uploading from
Simulator (or) Device will generates some irrelevant differences in terms of
section order change (or) whitespaces (or) special characters being introduced
on the project file. Unity DIF as such detects these differences and displays
them as Added / Deleted.
7.3 Description:
Server Samples provided along with the application must be 'Run as
Administrator' on Windows 7, Windows 8, Windows 10.
Details: Unity DIF needs elevated privilege levels to
run on Windows 7, Windows 8 and Windows 10. When a server sample is started
normally, it’s just a standard user process and Unity DIF will inherit the
privilege level of this process to run causing it to fail.
7.4 Description:
Repair function issue on Windows 8 and Windows 10
Details: Unity DIF repair function will fail on
Windows 8 & Windows 10 operating system, reinstall to resolve the issues.
7.5 Description: Schneider Electric License Manager
Installation issue
Details: If a message box appears during Schneider
Electric License Manager installation with a demand to find the original setup,
click NO to continue the installation.
7.6 Description: Unity DIF license activation issue
Details: If a Trial period reminder message box
appears to activate although the software is already activated, click NO to
continue.
