I have the TortoiseSVN->Settings->Diff Viewer -> Merge Tool set to: External with
D:\Program Files\KDiff3\bin\kdiff3.exe %base %mine %theirs -o %merged --L1 Base --L2 Mine --L3 Theirs I am using KDIFF3 version 1.11.0 (64 bit). My operating system is Windows 10 Enterprise version 22H2 OS build 19045.4529. Steps to reproduce. 1. Select a working copy of a file. 2. Open TortoiseSVN context menu and select Show Log. 3. On show log, select two revisions of a file. Right click and select compare revisions on the pop up context menu. An error dialog pops up with a title of File open error - KDIFF3 and a message in the pop up of: Opening of these files failed: - Mine Opening c:/users/.../AppData/Local/Temp/MainWindow.xaml.cs-rev75974.svn003.tmp failed. Unknown error. I can downgrade TortoiseSVN from version 1.14.7 to 1.14.6. I can perform the same operation, and KDIFF3 opens. The differences are displayed in KDIFF3. I tried the latest nightly build of 1.14.99 2024/06/21 21:48:08. This fails just like 1.14.7. Can you please fix this bug?
