In Settings: Winmerge 64bit custom Diff Viewer path keeps resetting to x86 path

[Grégoire de Ryckel]

Hello Team !

-what I did-
0- On new win10Pro
1- installed last version of TortoiseSVN 64bit
2- installed last version of Winmerge 64bit
3- accepted that the winmerge installer sets the integration inside TortoiseSVN
4- checked out a repository
5- looked at the log
6- double click on a modified file
7- error popup "could not start the diff program, system cannot find the file specified"
8- went in diff viewer settings and adapt path from "C:\Program Files (x86)\WinMerge\WinMergeU.exe" to "C:\Program Files\WinMerge\WinMergeU.exe" (click apply and ok)
9- double click on again on a modified file
10- I see the diff in winmerge
11- spend some time to develop on my development tool
12- want to check the diff before commit
13- double click on a modified file

-what I want to happen-
14- I see the diff in winmerge

-what actually happened-
14- error popup "could not start the diff program, system cannot find the file specified"
15- went in diff viewer settings and x86 path a again there

Whenever I change the path back to 64bit version from the settings pane (or event the registry), this behavior repeat itself in cycle

The settings is memorized for an hour aprox. and then set back to X68

TSVN does not modify that setting without user interaction.

You have to look for some tool that changes this setting - if you're not at home but at work, as your IT if they change the setting.
