Topic: Yesterday "AVFS 1.0.0.0" update. Result: No more frame interpolation.

Yesterday morning an "AVSF 1.0.0.0" or something similar update came for SVP. Result: No frame interpolation.
Worked perfect with the version from before. It there a rollback feature or a way to select "version from yesterday please" ?
My solution in "C:\Program Files (x86)\SVP 4\avsf":
1. Manually run unregister.bat.
2. Copy the "C:\Program Files (x86)\SVP 4\avsf" away, all files date 2021-05-14, avisynth_filter_64.ax size 399872.
3. Get yesterday morning shadowcopy, where all files have the date 2021-05-03, avisynth_filter_64.ax size 398336. Copy them back.
4. Manually run register.bat
Done! I don't even need to close SVP control panel, old version works. Side effect: The "Active log" states:
17:31:42.342 : AVSF: found 64-bit version 1.0.0.0 [C:\Program Files (x86)\SVP 4\avsf\avisynth_filter_64.ax]
which is wrong by the time it successfully worked after doing the steps above and rolling back AVFS without restarting SVP control panel:
17:45:52.296 : AVSF: found new player instance

Have fun debugging! And yes, I love windows shadowcopy.

kind regards,

Re: Yesterday "AVFS 1.0.0.0" update. Result: No more frame interpolation.

they changed the registry key for storing settings in 1.0.0
but SVP's update script should handle this, and I just checked - it does

please check  - do you have the "HKEY_CURRENT_USER\SOFTWARE\AviSynthFilter\AviSynth Filter" key?
and HKEY_CURRENT_USER\SOFTWARE\AviSynthFilter\AviSynth Filter\RemoteControl must be set to 1

Yes.

No.
I've manually added that DWORD value now, changed to the new AVFS, and interpolation works.

Question:Can I manually start that update script to test?

A possible reason: For quite a while svp-maintenance has been trowing an error during each update, that unregister.bat and register.bat exited with an error. But each time I run them from an elevated prompt they work fine. If only I could see what it does different during svp-maintenance run.. One thing that might unusual about my box: UAC is set to the highest value.

Attached: installation log (and all other files with the date/time of the last update).

yeah, this might be the reason for not updating the registry
