Error 5, 28.30.0200 (64-bit)

[Zardoz2293]

MacOS Tahoe v26.4.1 | Windows 11 Pro, 64-bit, 25H2.26200.8117 (10.0)
VM Scaling (Client Windows): Main=MacBook 4112 x 2658 @200%; External=3840 x 2160 @125%
===

Was working on 28.30.0100 (64-bit), then installed 28.30.200 = error 5, installed 28.30.201 = error 5, reverted to 28.30.100 now error 5 there too.

Only things recently changed was adding a new external monitor to the VM where Windows 11 (where XYplorer is used). Worked w/o issue. Disabled extended monitor and problem persists.

[admin]

Could you please send your action.dat (in folder <xydata>) file to support?

[Sander Bouwhuis]

Ok, I sent you my settings.
I really hope this can be fixed because Windows Explorer is a huge step back for me ;(

Is it possible to download an older version so I can work again? Or wouldn't that help me? It is really hampering me that I don't have access to Xyplorer (because of the scripts I use).

[admin]

Thanks for the files! It's fixed now. Upload soon.

[Sander Bouwhuis]

Ok, I downloaded the latest beta.
But, I used the 'installer' version. I think I may have been using the portable up to now (I REALLY need the settings to be in the Xyplorer directory itself, because I back up that directory).
1. Will my version still be the portable version where all the settings are in the directory itself?
2. Will my version auto update like usual (i.e., NOT beta versions)?

v28.30.0401 VERIFIED WORKING: This solved the Error 5 I was encountering in my action.dat file.

THANKS!

Of course, the log should never get corrupted in the first place. I'll investigate that later.

[admin]

Getting closer. It's a tB bug. Once it's fixed, the cross-session undo log will be back in business, even for larger jobs (currently it hits a 64KB data limit).
