Today I have tested it and the bug is confirmed by me and also already by IDM. UltraCompare Lite v4.10 released with UltraEdit v12.10b is not capable to compare files in fast binary mode because it immediately crashes (I guess a missing resource or code part in the Lite version).
UltraCompare Professional v4.10 does not have this problem and also UCL v4.00a which is in the installation packages of UEStudio 6.00 and UltraEdit v12.10a does not have this problem.
Here is the answering email from IDM support which I have received exactly 30 minutes after sending the bug report email.
Hello Mofi,
Thanks for your message. I have logged this issue in our database.
I can send the user the UltraCompare lite 4.00a as a zipped attachment if they would like.
Thanks, Andy
yzkzero, looks like you have not reported it to IDM. As a registered user which you hopefully are, you have the right to contact the IDM support and you will get it without any additional costs.
