Rename files in batch mode

[Hagen]

Hi Everyone, I would like to rename files in batch mode according to this pattern:
$E36868(%Y.%m.%d_%H:%M:%S).jpg
but I get this by example: 2019.07.10_11_11_40_32.jpg .
An underline is placed instead of a colon.
I work with Win10, IfranView Version 4.58 - 32 bit
Could you please help me.
Regards Hagen

The colon does as you say.
Try using a period instead to get: 2021.01.01_16.24.22.jpg etc.,

Filename pattern: $E36868(%Y.%m.%d_%H.%M.%S).jpg

I had already tried other punctuation marks. All of them work correctly except for the colon. Thanks for your help and patience.

In addition to Bhikkhu Pesala's answer: Windows does not allow a colon in filenames. A colon is only allowed in combination with a single letter to represent a
logical drive on your computer, e.g. "C:" .
