Configuration compare failed

[HPM]

Hello,
I successfully backed up and viewed the configuration files.
But when trying to use the compare feature in "Service > General Configuration Compare" I get the following error:
Failure
Reading and writing source file failed.
Intelligent Management Platform (JG747AAE) iMC PLAT 7.2 (E0403)
Installed on a Windows Server 2008 R2 Standard, SP1
Where does the software try to read and write the files?
Which permissions for folders and files are required?

Kind regards,
HPM

Try from:

Service > Your device (x.x.x.x) > Configuration Management

Configuration History

And  try compare from here.

Location: Program Files\iMC\server\data\cfgbak

Thanks for your hint.
Comparing configs in the "Configuration Backup History" tab of the device works fine.
Kind regards,
Peter
