I also note that unlike most other coolmuster products this DOES NOT SHOW AN EXPIRY DATE ON THE LICENSE so might not be an expiring license! Using runasdate I set the date to Jan 2028 and the program still reported as registered so it’s a good bet this is a lifetime license not a 1 year expiring one… just wish it was not such a Documents folder polluter!
you can bypass the license expiring by using nirsoft runasdate.exe to set the system date to a date within the valid license period.
Also why does this abuse the logged in users Documents folder by placing two folders containing data files in the Documents folder?
C:\Users\WINDOWSLOGINNAME\Documents\Coolmuster files\Coolmuster SignPub\Log
and
C:\Users\WINDOWSLOGINNAME\Documents\iStonsoft\ePub Editor\scratchpad
Who is iStonsoft? are they the original authors or another name Coolmuster pretends to be to the western world?
Means I am going to have to modify my real-time backup job to exclude these folders containing unwanted files from in my backups…
