TortoiseSVN: Could not start external diff program!

[radhi....@gmail.com]

Hi,

I have setup Beyond Compare as the external diff tool for Tortoise SVN and I have been using it since a long time to compare different revisions of a file in SVN repo.
Suddenly from today, I get an error saying "Could not start external diff program! %1 is not a valid Win32 application".
I updated TortoiseSVN to the latest version. I also verified that Beyond Compare executable is independently working by comparing two files using Beyond compare.
I also removed the existing configuration for diff tool in Tortoise SVN and reconfigured Beyond Compare.
I also updated Beyond Compare to the latest version and verified is it working with a valid license by comparing two different files in Windows.

Can you tell me how to resolve this issue? It is quite a nuisance to suddenly find that something that was working is now no longer working.

Regards

Does the default TortoiseMerge work?

Usually this error happens if you configure the diff tool wrong: paths that have spaces in them need to be in quotes, e.g. "C:\program files\difftool.exe" and not C:\program files\difftool.exe

Tortoise merge works fine. I did have a space in the difftool path, enclosing the path in quotes solved the problem.

Many thanks Stefan.
